When should I change the timing belt?

There are different opinions regarding how often the replacement of the timing belt Toyota Camry and other cars should be carried out. A classic option is considered every 90 thousand overcomed run. But in practice, this indicator is very often twice as smaller due to poor-quality roads. Therefore, it is better to focus on explicit visual signs, and not be lost in guesses. These indicators are as follows:

• oil traces on the belt;
• irregularities and cracks;
• beware of the end surface.

Did these signs of the timing belt wear? Then please contact the technical center "Autopilot"! Replacing the belt Toyota Camry, Corolla, Prado and any other car model from us will be spent high quality and inexpensive!

Timing belt Toyota Corolla is to be replaced after 75 - 100 thousand km of mileage, depending on the type of engine and is indicated in the instructions for a specific engine. The belt must be replaced in advance, since the belt breaks often leads to disastrous consequences - the pistons of the valve bend and the resulting engine repair is required.

Preparatory work

To replace the timing belt, install toyota car Corolla on a flat site and fix the parking brake. Disconnect the terminals and remove the battery from the car. Disconnect high voltage wires And unscrew the spark plugs.

Remove the belts of the air conditioner and the belt hydraulic pump. On the mechanical box gears turn on any transmission if installed automatic box - Fix the flywheel through a special slot in the hydromefta crankcase.

Procedure for performing work

Unscrew the nuts on valve cover And slightly lift it. Remove fasteners nuts upper cover timing belt and then remove the lid.

The label on the crankshaft pulley align with the label indicated by the number 0 on the bottom cover of the timing belt. In this case, the hole on the camshaft pulley indicated by the 2e should be at the top, and the label on the engine block should be visible through this hole. If the labels do not match, turn the crankshaft to one turn.

FROM right side Remove the lid opposite the crankshaft pulley. Loosen the tension of the generator belt and remove the belt. Fix the crankshaft pulley with a solid mounting blade or a suitable metal pin. Do not paste the shovel too deep enough to damage the rear belt cover. Unscrew the pulley bolt. The bolt is delayed very much, so use the end key with the extension.

Remove the bolts and remove the Lower Timing Belt, also remove the puck guide. Loosen the tightening of the bolt tensioner roller, Press the roller from the belt and fix the bolt again. Now remove the timing belt.

Remove the tensioning roller spring. Remove the bolts and remove the stretch and rollers. Examine the rollers and check for defects. In the presence of traces of work out from the belt, traces of rust or other defects, the rollers must be replaced. When rotating from hand, the rollers should scroll no more than half the turnover, otherwise the rollers need to be replaced.

Replace the rollers. Install the spring on the tensioner, then press the roller until it stops and secure the bolt. Check if the tags on the pulleys did not shift and adjust their position if necessary.

Starting from the bottom up, put the timing belt on the pulleys, while the freely saving part of the belt should be from the side of the tensioning roller. Release the tensioning roller and pull the belt, while the labels should not shift. If the labels are shifted, reinstall the belt.

Replace the seat of the guide washer and the bottom limit of the timing belt. Turn the crankshaft to 2 turns and check the label match again. If the labels do not match, remove the strap from the camshaft pulley, correct the position and again check the matching of the labels, checking the crankshaft by two turns. Repeat this operation to the complete match of all tags.

Replace the top cover of the timing belt and the pulley of the generator belt. Put on the pulleys and pull the generator belt. Screw the candles to the place and connect high-voltage wires. Tighten the valve cover mounting bolts.

Install in place and secure the battery. Check if all the details are set to their locations and in the correct order. After that, connect the terminals to the battery and start the engine. Check for the installation of the ignition, it may be necessary to adjust it.

Timing chain B. Toyota Corolla 120 and 150 is a very reliable detail: its resource is 200 thousand kilometers. Some believe that the chain never needs to be changed, and it is wrong. With huge runs, this detail is stretched and wear out, which can lead to serious consequences.

Signs of worn out details

There are several symptoms for which it is determined whether the chain should be changed:

1. It rattles when the engine is running.
2. Scrace on the wall of the lid.
3. It can be seen that heavily saves

It is recommended not to save on this spare parts and choose only the original, because it affects the integrity of the engine and changes once every 200 thousand kilometers. It is better to spend money for five years once and be sure that the motor valves will be in order.

The chain is much more reliable than the timing belt and works at times longer, but each medal has a different side: it is much more difficult to change it and more expensive. For those who want to replace it alone, the detailed instructions are given below.

How to change the timing chain on Corolla 150

To replace the timing chain in the engine, Corolla 1Zr Fe must be changed: asterisks, tensioners, soothers. You can immediately purchase Repair Kit, in which all this is available.

It's important to know! If you do not change the whole set, the new chain can very quickly fail.

On Toyota to replace it is necessary to remove hinged equipment From the engine:

1. Top cover.
2. Side lid.
3. Belt (behind the side lid).

The first thing for replacing the timing chain to 1.6 2008 and other releases, it is necessary to remove the front right wheel, there will be rubber protection that can be moved into the photo:

After the protection is moved, the lid will be visible on the motor with which you need to unscrew the bolts, after which it is removed. After her dismantling will be visible a chain:

Important! The timing chain must be placed on the labels as in the photo below. On it, there are links, the color of which is different from the rest. In different sets, these colors are different, in our case two levels are just darker. The label designated by the red arrow should stand strictly between two links that differ in color.

In 1 ZR FE on the left asterisk of the gas distribution mechanism, there will be a label that should get into the middle of the link, which will differ in color as in the photo.

Now we wear a chain from the bottom, through the window from which we removed the protection. Visually will be seen that it is relaxed, but it is necessary. Then she attaches to the right position the tensioner, the replacement of which we produce the following action.

The hydraulic sensor is located in the side cover, which we removed. Unscrew it from there and screw the new one. It is necessary that it be in the corded position.

The next action should be scrolling the crankshaft clockwise to a couple of revolutions. After that, the hydroletlayer will work and pulls the chain-saving bottom.

How to replace the timing chain and tensioner on Corolla 120

Chain

In order to have access to the rear of the motor, it is better to remove the entire system of janitors: the drive and brushes themselves. After that, dismantle the engine cover, under which there are shafts that are responsible for gas distribution.

Just as in Corolla 150, it is worth removing the front right wheel, followed by plastic protection. After her dismantling, the so-called window will appear through which the crankshaft pulley will be seen.

Remove the belt simply: to dismantle the spring of his tensioner, after which it will start harder.

Now you can remove the side cover on which the pump is located (also remove). After these preparatory work, we remove the chain itself. Through the window in the arch wheel, a sprocket is seen, which is delayed in two positions. Having drawn it, you can easily get the old chain, then put a new one.

Tip! It is better to change the set with asterisks and tensioners. If some of these elements are worn out, the new chain will come into disrepair.

On the chain drive Toyota Corolla, there are links that differ in color. They may be darker / lighter than others or at all of another color.

Different links should fall strictly by labels on gears.

Perhaps you have to twist one of the stars, in order for the tags coincided.

Tensioner

After installation, we replace the chain tensioner.

When it is installed, it is necessary to ensure that the rod is depressed, and the latch is crushed as in the photo.

In a non-pressed position, the rod looks like this:

There should be a gasket between the tensioner housing and the engine that should not be stuck. In any case, it is better to change it, because the new comes in the kit.

We turn crankshaft Auto counterclockwise to characteristic ratchet sound. It is necessary so that the same latch in the photo bounced off, and the tensioner entered into its working position.

Important! The car can be started only after the latch bounced, because when the tensioner is not working, the chain is not stretched and can jump.

The last operation must be scrolled clockwise in order for all elements of steel to place.

After starting, the first couple of minutes can be heard the characteristic sound of the sorcement. There is nothing terrible in this, just the tensioner has not yet fully received the oil.

Conclusion

There is a lot of disputes, which is better: chain or belt. The first option is more reliable, and the second is much easier to change. If you do not have the confidence that you can replace yourself, it is better not to take for this business and leave it a good specialist. Due to incorrect installation of the chain can break the engine. In addition, from the entire range of items it is necessary to choose only the original, which will work at times more.

On the Motor of type 4A FE, on the basis of which 3zz-Fe was built with a brand system from Toyota VVT-I, a belt transmission is installed. The frequency of replacing the timing belt Toyota Corolla is 100 thousand kilometers.

Some factors should be taken into account. According to them, adjustment is made towards reducing the life of the belt. The release of the car on which 4a Fe was installed, ceased in 1998. therefore most of The engines have quite large mileage. And the timing belts, made under license, are always operating less than the original.

Replace the Toyota Corolla, if necessary, can be combined with such accompanying work as:

• replacement of the front oscillation of the crankshaft;
• replacing the glands of the candlestone;
• replacing the coolant pump.

In later generations, the replacement of the timing chain on Toyota Corolla is always produced at large mileage. The need for this procedure is determined by characteristic features. For example, on the noise of the chain occurring during the operation of the motor. Sometimes they resort to the help of the defectation of the main parts - chains, stars.

Procedure for performing work

Before replacing the timing belt on Toyota Corolla, take the necessary spare parts. Prefer original detailswho recommends the manufacturer. For replacement will need new belt Timing and tensioner roller.

Do not forget that the item during installation is not recommended to be bent, especially in the opposite direction.

In order to know how to change the timeline chain to Toyota Corolla, use the other manual. The sequence of the chain drive replacement is different from those that need to be carried out in engines equipped with belt transmission. However, if you independently managed to replace the belt of the gas distribution mechanism, then the chain can also change without any problems.

As you know, for the normal operation of any car, all its nodes, aggregates and mechanisms must function properly. Toyota Corolla cars, like other foreign cars, of course, break less often domestic cars. However, this does not eliminate the owners of these models of cars from time to time to replace the belt or timing chain. Below you can find out in what cases it is necessary to implement this procedure and that it will be necessary.

The need to replace the element

The question of the need to replace the chain or the timing belt sooner or later will appear before any car owner Toyota Corolla. The performance of the chain and belt must be paid due attention, since the GDM mechanism itself is an important device. With its inoperability, the start of the engine will be impossible. If you have noticed something that is not something wrong with your chain or strap, and the symptoms below manifested themselves in your Toyota Corolla, it is impossible to replace the element.

How to understand that the chain or the timing belt came into disrepair and their replacement is necessary:

• in the event that the chain or belt has already worked out its resource of operation and their appearance leaves much to be desired;
• if cracks or other traces of mechanical damage appeared on the mechanism component (especially cracks are clearly manifested if you hit the strap);
• if you have seen oil traces on the chain or belts (before replacement, the cause of the motor fluid leakage should be eliminated);
• if the structure of the strap began to come into disrepair, that is, the upper layers began to be tracked from it, threads.

Well, of course, the replacement of the belt or chains should be carried out in accordance with the requirement of the manufacturer. The Toyota manufacturer recommends that all owners of the Corolla carry out this procedure at no less often than every 140 thousand km of run. But Russian and Ukrainian dealers recommend doing it at least than when running 100 thousand km. In practice, the chain or belt is rhat or comes in disrepair on this mileage.

Replacement process

Tools

So that the procedure does not take a long time, you need to prepare everything in advance:

• spanners;
• two screwdrivers;
• jack.

Phased instruction

1. First, turn off the battery and install your Toyota Corolla on the parking brake. Put the supports under the wheels so that the car reliably stood on the spot.
2. Using a jack, lift the front of the car and substitute bricks under it, and then unscrew the bolts of attaching the right front wheel. The front wheel together with the bumper body kit can be removed.
3. Next, unscrew the spark plugs, then dismantle all drive straps.
4. In the photo, the arrow marked the intermediate roller of the air conditioner strap, it needs to be dismantled.
5. If your Toyota Corolla is equipped with a cruise control actuator, then it needs to be unscrewed and removed to the side. After that, disassembling the cover of the GBC.
6. Under the motor you need to put the stand, but it should not be restricted into the plug hole of the engine fluid.
7. Now you need to install the piston of the first cylinder into the upper dead point of the compression tact. After that, you will need to pose and pull out the lid of the observation hatch, for which you will fix the flywheel in advance with a screwdriver so that it does not turn. If someone helps you, then ask a friend to unscrew the crankshaft screw, since it will not be done very comfortable. The crankshaft drive itself must be dismantled without problems.
8. Dismantling the lids of the gear strap. The timing belt flange must be dismantled, but before you remember its location. In particular, the rolled part of the element must be turned outward.
9. Then you will need to weaken the spanner tightening the tensioning roller adjustment pin. The roller itself will need to be pressed inward so that it does not interfere, and the screw will need to be tightened again. The timing belt can be removed from the slave gear. In the photo of two arrows, the nuts of the Motor mounting support are noted, they need to be unscrewed. You must also unscrew the upper screw marked with an arrow, and omit the motor, then pull up the bottom of the support and stretch the strap between its upper and lower sections.
10. Remove the strap from the drive gear and pull it out of the workpiece. In the event that the condition of the lead gear is not particularly inspiring, it must be replaced.
11. Then you will need to mark the position of the upper dead point of the element on the gear and oil pump to new element It was installed correctly. The entire further procedure for installing and setting tags should be carried out in reverse sequence. If you did everything right, then you will not have any problems.

The timing belt itself when replacing it is forbidden to turn inside out, it is also impossible to make it supplies - oil, antifreeze or fuel.
