What is installed on a Ford Focus 3, a timing chain or a timing belt, is useful for every car owner to know. It is believed that the chain mechanism is more reliable and durable, but replacing the chain is more expensive than the belt, and the process itself requires disassembling the engine.

Is the timing chain or belt installed on a Ford Focus 3?

On Ford Focus 3, depending on the type of engine, it is installed both belt and chain drive.

The chain is installed on 2L 150HP engines. All 1.6L engines have a timing belt.

Timing Belt Ford Focus 3

On a third-generation Ford Focus car with a 1.6 engine, a timing belt drive. Replacing the timing belt is required approximately every 80,000 km. This figure may vary depending on the degree of belt wear. If signs of wear appear, the belt must be replaced.

How to check the timing belt?

Check the condition of the timing belt regularly. To do this, turn the crankshaft and inspect the entire surface of the belt for damage (cracks, abrasions, undercut teeth, folds).

Timing belt Ford Focus 3: price

If you need to replace the timing belt, the cost of services in the service will be about 2,000 rubles, not counting the price of a new belt. How much this belt costs depends on your preference. The original with catalog number 1675963 will cost 1,500 rubles. The main manufacturers of analogues are:

Gates (article 5669XS) - 500 rubles.
Bosch (article 1987949667) - 900 rubles.
Dayko (article 941049) - 900 rubles.

Which belt to buy depends on personal preference. All of the belts listed will fit a car with a 1.6 105 and 125 hp engine.

Much greater costs will be required if the idler roller needs to be replaced. The original timing belt roller for Ford Focus 3 (catalog number 1 376 164) costs 7,500 rubles.

Timing belt howl Ford Focus

The howling of the timing belt Ford Focus often speaks of the need to replace it due to wear.

When a howl appears, you should carefully inspect the timing belt and the mechanism itself for damage. In some cases, the howl indicates that oil has entered the belt. The reason for this, again, needs to be identified and eliminated. In this case, belt replacement is usually not required.

Consequences of untimely replacement of the timing belt

The main consequence of untimely belt replacement is its breakage. As a result of this, the valves most often bend, which requires an expensive major overhaul of the engine. It is clear that it is better not to bring it up to the moment when the timing belt broke.

Where to change the timing belt?

As mentioned above, replacing the belt in the service will cost at least 2,000 rubles. If you have instructions, you can replace the belt yourself (read the article "Replacing the timing belt Ford Focus 3"). Particular attention in the process of installing a new belt should be paid to the timing marks, which are located on the crankshaft and camshaft. If, after installing a new belt, any difficulties arise, you should immediately contact a specialist.

Good afternoon. In today's article we will tell you how the timing belt is replaced with a Ford Focus 3 with a 1.6 105 hp engine. The given photo and video instruction will allow you to replace the timing belt with your own hands.

What is the mileage to change the timing belt?

To eliminate unexpected troubles and avoid problems at the most inopportune moment, timely replacement of the timing kit and drive belt will help. Of course, manufacturers claim that the belt is designed for operation over 120 thousand kilometers, but this does not take into account the difficult operating conditions of the machine in large cities, harsh climatic conditions. In practice, the need for replacement occurs with a run of 80 thousand kilometers.
In order to detect malfunctions in time, it is necessary to carry out diagnostics once a year.
It is imperative to replace the belt if:

there are oil smudges in the area of the front cover;
folds, cracks or other defects are visible on the jagged surface;
cavities or swellings appear on the belt;
the edges are disheveled.

Do not forget, if you find oil smudges, an urgent replacement is required, as the rubber from which the belt is made is destroyed, which will lead to a break. In addition, it is required to eliminate the cause of oil leakage - a violation of the tightness of the oil seals. If this is not done, oil will continue to drip onto the new belt.

So, to replace the timing belt with a Ford Focus 3, we need:

Straight arms
quality timing belt.

Purely theoretically, replacing the timing belt without the use of a special tool cannot be carried out. Additionally, an X-shaped metal plate is required - a camshaft clutch retainer and crankshaft and tension roller clamps.

To get the job done, we need:

Timing belt (set) art. 1672144
V-ribbed belt art. 1692105
Crankshaft pulley retaining bolt art. 1677517
Crankshaft oil seal art. 1473807
Valve cover gasket art. 1319177
Quick cleaner Partner art.77701.

The procedure for carrying out work on replacing the timing belt with your own hands.

Attention! Before carrying out work, remove the positive terminal from the battery!

Video instruction for self-replacement of the timing belt Ford Focus 3:

If you do not have the opportunity to watch the video, or if you are more used to reading:

1. We start by removing the drive belt. Then remove the generator terminal protection and unscrew the 3 mounting bolts.

2. The generator and the expansion tank of the cooling system will interfere with the actions to replace the timing kit. Therefore, we dismantle the generator. We remove the expansion tank from the brackets and take it a little to the side. Do not disconnect the hoses, do not drain the antifreeze.

3. The next operation is to remove the water pump pulley. To do this, unscrew the four bolts.

4. We put a jack with a wooden block under the engine.
5. We unscrew the two nuts on which the support of the aggregate suspension is fixed.
We also remove the mudguard attached to two bolts. We dismantle the right motor mounts; in this case, it will be necessary to hang out the motor and install a support.
6. The turn came to the top of the engine, where the gears of the camshaft couplings are located, which must be secured against turning. For this we need a special device. It must be installed so that the labels located on it are at the top:

7. Press the brake all the way in fourth gear to secure the crankshaft from turning. We unscrew the bolt securing the pulley to the crankshaft. This bolt is not reused!
8. Remove the lower timing case cover after unscrewing 3 bolts.

9. We remove the belt, during the procedure it can be cut.
10. Install the new timing kit, which includes the belt and roller, into place.

11. We carry out the assembly of previously dismantled parts. We do everything in the reverse order.

The procedure for tightening the NEW crankshaft pulley bolt is 100Nm, then turn it 90 degrees, then wait 20 seconds and turn it another 15 degrees! This is not shown in the video!

12. We change the drive belt, which will help us to install another special tool of an unusual shape.

This is how the whole operation to replace the timing belt kit looks like, which takes about 4-5 hours.

Conclusion.

As you could understand, replacing the timing belt with a Ford Focus 3 with a 1.6 engine (105 hp) is quite feasible with your own hands and allows you to save 3-5 thousand rubles. It is important to remember that this work must be done very carefully, because one wrong step can lead to problems.
Don't forget to use high quality consumables to keep your vehicle running for a long time!
That's all for today, I hope if you still have questions, or if you want to supplement the article, write comments.

Ford Focus 3 is considered a reliable car all over the world. Its engine is a single organism, where all systems work harmoniously, and fitted parts down to a micrometer affect each other in one way or another.

The normal operation of the crankshaft and camshafts directly depends on the state of such a part as the timing belt Focus 3. Replacing it is inevitable - over time, the tensioning element of the gas distribution mechanism will become unusable.

And if it is worn out, very soon you can expect it to rupture, stop the engine and considerable expenses for the repair of its components. But all this can be avoided if the motorist simply replaces the belt on time.

What affects the state of this timing element?
When is it needed to be replaced?
How is it produced, and what is needed for this?
Is the price for the "Ford Focus 3 timing belt replacement" service high?

Customers of our car service are interested in all this. For them, our masters will give detailed explanations.

Timing belt Focus 3: replacement, service price

In our car service, the cost of replacing this element of the gas distribution mechanism is one of the lowest in the region. Although the procedure itself, taking into account the location of the belt, takes some time even for our experienced craftsmen. Another thing is the price of the part itself.

Originals: the price of genuine Ford tensioners is, of course, higher. But they have a definite plus - they are completely suitable for the type and geometry (dimensions and center distance). Or, as motorists say, “they will stand up like family,” which means they will last longer.

FOR REFERENCE! The original part does not have to be made by Ford - for the Focus 3, the tensioning parts can be produced by companies under a different brand. But they are all produced under the Ford brand, that is, they are ideal for Focus 3 (an indication of the brand should be in the documentation).

Analogs. There are also quality analogues. Non-original timing belt Focus 3 replacement, price and quality may not differ too much from the original. They do not have a brand label on them, but they may match the characteristics. Among those that are popular and suitable for Focus 3, there are two brands:

Bosch from Germany. The company is famous in Russia for the quality of its products. The company also manufactures components for other automotive systems.
Dayco from Italy. A company specializing in the production of timing belts.

Fakes... It is unnecessary to talk about cheap parts from Asian countries, counterfeit brands or even analogs. Their experienced auto mechanic eye will distinguish right away. They usually do not last long. Therefore, those who decide to save money will have to pay twice. In our car service, replacement belts are ordered only from trusted dealers.

Consequences of damage to the timing belt on Focus 3

It is extremely rare that a belt breaks suddenly and completely unexpectedly for a motorist. It wears out for a long time, it can take several years. And it is quite difficult not to notice signs of wear on it in a timely manner:

cracks;
chips;
cuts;
folds;
detachment.

There may also be traces of oil, which indicates the need for a comprehensive diagnosis and elimination of the causes of the leak.

If you postpone a visit to a car service indefinitely, the consequences of a belt break can be as follows:

The valves will bend.
The pistons and working chambers of the cylinder head will suffer.
The coupled units will receive irreversible damage.

Replacing the belt alone will not be enough. It will take a lot of investment, patience and time to bring the Focus 3 back to life. And the price of all timing components for the Focus 3 makes you think.

When does the manufacturer prescribe to replace the belt with the Focus 3?

According to the regulations on Ford Focus 3 cars, this timing element must be replaced:

for versions with a 1.6 liter engine - every 120 thousand kilometers;
for other versions - after 150 thousand kilometers.

By time: in the first case, at least once every eight years, in the second - ten.

ATTENTION! These are the official figures, that is, the average service life, within which Ford assumes the preservation of the operating condition of the timing belt on the Focuses-3. In practice, everything looks a little different - any experienced auto repairman will tell you about this.

How much does the timing belt actually serve on the Focus 3?

It may well happen that the belt will require replacement when the car has not passed even half of the mileage indicated in the documentation (that is, 60-80 thousand kilometers).

His condition is influenced by:

Much depends on the road on which the Focus 3 is constantly moving. If it is used almost all the time within the city, the speed changes regularly - the car stops in front of traffic lights and accelerates between intersections. If he moves more often on an open track, the speed is most of the same. Over the course of several years, the difference in these speeds will affect belt wear.

Operating conditions

Too high temperatures in heat or too low - in frost they affect the surface of the reinforced rubber of the timing belt. Such harsh climatic conditions, or rather their change, are characteristic of Russia. Therefore, one or another share can be taken away from the resource set for countries with a milder climate.

Year of car manufacture

The factory belt installed on the Focus 3, which has just rolled off the assembly line, lasts longer than the element that will replace it after a certain period of time. This fact, relating to any other car, has long been noticed by experienced craftsmen. The fact is that the new timing belt, installed instead of the old one, is affected by the condition of other parts and assemblies, which, over time, move further and further from the ideal state.

Belt tension

The tension should be optimal. It is better to check it with the help of instruments. With a strong constriction, not only the belt itself wears out faster, but also the rollers with a pump. If the tension is weak, the belt may slip, which will disrupt the timing of the timing.

Preparing to replace the timing belt with Focus 3

It is difficult to argue with those military leaders who were sure: "To prepare for a war means to win it halfway." In the case of belt replacement, the situation is exactly the same.

The master, even before starting work, even if he has considerable experience, asks the client about what year the Focus 3 was made, what its mileage was, under what conditions it was used, whether the timing belt had changed before, etc. Details can be specified according to the timing scheme for Focus 3.

After that, the instrument is prepared.

From the standard set you will need:

socket wrench for "10"
heads or spanners for "8", "13" and "18".

Of special devices and tools, you will need:

Adjusting bar - it is needed to fix the camshaft in a stationary position.
Template - so that the phase regulators do not scroll.
Various clips - they will allow you to fix the crankshaft.
Stopper - it is installed on the crankshaft flywheel crown.
Stud - in order to immobilize the timing belt tensioner plunger

If, when repairing other mechanisms and systems, you can do with a standard repair kit, then in the case of a timing belt, you cannot do without these special devices.

FOR YOUR INFORMATION! An error of at least a degree without the use of clamps can lead to the need to re-dismantle the timing belt.

Preparation for work makes it much faster and easier. When the details are clarified and the tool is prepared, the wizard gets to work.

How is the Focus 3 timing belt replaced?

The procedure itself is not overly complicated. A master with experience and the right tool, with quick and accurate movements, is able to perform it without much difficulty.

Most of the work is just to get to the belt and make it possible to dismantle it. At the same time, extreme care must be taken in everything.

It is required to perform the following manipulations:

DANGEROUS! In no case should you turn the crankshaft with the part removed - this will break the valves by the pistons.

Our car service also provides a service for inspection, checking and (at the request of customers) replacement of the tension roller, drive belts, crankshaft pulley and its bolt and associated parts.

Correct operation of the timing belt Ford Focus 3

Summing up the words of professional auto repairmen, we can conclude that:

For normal operation of the Focus 3 engine, you need a workable timing belt with optimal tension.
Traces of its wear and damage (cracks, cuts, delamination) are easy to notice upon a superficial examination. It is recommended to produce it without relying on the official regulations of the manufacturer. This is dictated by the specific operating conditions of the car Focus 3: on what roads it constantly moves, what constant climatic temperatures affect it, whether the timing belt has already changed, what level of tension it has.
Before working on changing the belt, special devices should be prepared so that the whole procedure takes as little time as possible.
And for competent and accurate replacement experience is required.

Our car service offers the services of professionals who:

They will quickly, competently and inexpensively replace the timing belt with the Focus 3;
Diagnose and troubleshoot other systems, mechanisms and parts that affect the operation of the gas distribution mechanism;
They guarantee the quality of all work performed.

Ford Focus 3 engine 1.6 liter was developed in the early 2000s. Since October 2015, Duratec 1.6 TI-VCT has been produced in Russia at the new auto-aggregate plant of the American concern. The engine is installed on Russian Ford Focus, Fiesta and even Ecosport. Structurally, the same motor has power of 85, 105 and 125 hp. The power difference is achieved exclusively by individual firmware of the control unit (ECU). Accordingly, the cheaper basic versions of the Focus get the 85 strong version, and the more expensive 125 strong version of the motor. This is more of a marketing ploy than a technically justified difference. The atmospheric gasoline engine has a variable valve timing system on both camshafts and a timing belt drive. We will talk about the other features of the motor further.

Engine device Ford Focus 3 1.6 l.

The Duratec 1.6 TI-VCT engine is gasoline, four-stroke, four-cylinder, in-line, sixteen-valve, with two camshafts. The location in the engine compartment is transverse. The order of operation of the cylinders: 1-3-4-2, counting - from the pulley of the drive of auxiliary units.

The power supply system is a phased distributed fuel injection (Euro-5 toxicity standards). The engine with gearbox and clutch form a power unit - a single unit, fixed in the engine compartment on three elastic rubber-metal bearings. The right support is attached to the bracket located on the right wall of the cylinder block, and the left and rear support to the gearbox housings.

On the right side of the engine (in the direction of the vehicle) there are: the drive of the gas distribution mechanism (toothed belt); drive of the coolant pump, generator and power steering pump (poly-V-belt); air conditioning compressor drive (poly V-belt); oil pump.
On the left are: the ignition coil, the coolant outlet and the coolant temperature sensor.

Front: intake manifold with throttle assembly, fuel rail with nozzles, oil filter, oil level gauge, alternator, starter, power steering pump, air conditioning compressor, thermostat, crankshaft position, knock and insufficient oil pressure sensors.
Rear: catalytic manifold of the exhaust system, phase sensor. Top: spark plugs.

Cylinder block Ford Focus 3 1.6 liter Cast from an aluminum alloy using the Open-Deck method with free-standing (in the upper part of the block) "wet" sleeves. In the lower part of the cylinder block there are crankshaft supports - five beds of the main shaft bearings with a plate common for all beds (removable cover), which is attached to the block with ten bolts.

In the block, the main part (except for pistons and connecting rods, of course) is a crankshaft made of high-strength cast iron, with five main and four connecting rod journals. The shaft is equipped with eight counterweights, made on the continuation of its "cheeks". Counterweights are designed to balance the forces and moments of inertia arising from the movement of the crank mechanism during engine operation. The liners of the main and connecting rod bearings of the crankshaft are steel, thin-walled, with an anti-friction coating.

The main and connecting rod journals of the crankshaft connect the channels drilled in the shaft body, which serve not only to supply engine oil from the main to the connecting rod bearings, but also for centrifugal cleaning of oil from solid particles and deposits when the shaft rotates. At the front end (toe) of the crankshaft, the following are installed: a toothed pulley for the drive of the gas distribution mechanism (timing) and a pulley for the drive of auxiliary units.

The head of the block of cylinders of the engine Ford Focus 3 1.6 l.

The head of the Duratec 1.6 TI-VCT block is made of an aluminum alloy. The camshafts are driven by a toothed belt from the crankshaft pulley. An automatic tensioner ensures the required belt tension during operation.

The valves in the cylinder head are arranged in two rows, V-shaped, with two intake and two exhaust valves per cylinder. The valves are actuated by camshaft cams through cylindrical tappets. Eight cams are made on the shaft - an adjacent pair of cams simultaneously controls two valves (intake or exhaust) of each cylinder. Supports (bearings) of the camshafts (five bearings for each shaft) are split. The holes in the supports are machined complete with covers.

Engine oil pump Ford Focus 3 1.6 l.

Engine lubrication - combined. Under pressure, oil is supplied to the main and connecting rod bearings of the crankshaft, to the pairs "support - camshaft journal". The system is pressurized by an oil pump with internal gears and a pressure reducing valve. The oil pump is attached to the cylinder block on the right. The drive gear of the pump is installed on the flats of the toe of the crankshaft. The pump takes oil from the oil pan through the oil receiver and feeds it through the oil filter to the main line of the cylinder block, from which oil channels go to the main bearings of the crankshaft and the channels for supplying oil to the camshaft bearings to the cylinder head.

Timing drive of the Ford Focus 3 1.6 liter engine.

Gas distribution mechanism Focus 3 1.6 belt. If the timing belt breaks, the valve bends, so replacement must be done strictly according to the manufacturer's regulations. A feature of the engine with a variable valve timing system can be considered the presence of phase change actuators attached to the camshaft pulleys. In the case of replacing the timing belt, it is necessary to rigidly fix not only the camshafts, but also the phase change actuators with special devices. As in the photo below.
