How to replace drive belt - 1994 Toyota Corolla

which engine option, you do know belts are not same on all engines right? fact.
2.7L V6 or bigger? IDN.

same on all cars. (answering in generic form do to above)
loosen the tension-er.
take off old
put back new
and if not a spring tension-er,set proper tension
the fSM cover all this.
why not read the manual, RTM?

here is one example (get the book, RTM or see alldata.com)

INSPECTION

See Figures 1, 2, 3, 4 and 5
Check the condition and tension of all drive belts every 12,000 miles, or at least once a year. Loose drive belts can lead to poor engine cooling and diminished alternator, power steering pump, air conditioning compressor, or emission air pump output. A belt that is too tight places a strain on the bearings in the driven component.

Fig. Fig. 1: There are typically 3 types of accessory drive belts found on vehicles today

Fig. Fig. 2: An example of a healthy drive belt

Fig. Fig. 3: Deep cracks in this belt will cause flex, building up heat that will eventually lead to belt failure

Fig. Fig. 4: The cover of this belt is worn, exposing the critical reinforcing cords to excessive wear

Fig. Fig. 5: Installing too wide a belt can result in serious belt wear and/or breakage
Replace any drive belt that is glazed, worn, cracked, or stretched to the point where correct adjustment tension is impossible. If two belts are used to drive a component, always replace both belts when replacement is necessary. After installing a new belt, run the engine for ten minutes, shut OFF the engine and recheck the belt tension. Readjust if necessary.

ADJUSTMENT

See Figures 6, 7, 8, 9 and 10

Fig. Fig. 10: Engine belt tension chart-1994-95 models
Two popular methods of checking drive belt adjustment are; the Belt Tension Gauge Method and the Belt Deflection Method. The former requires a special gauge and the latter requires a straight edge and scale or just a good eye for measurement. The deflection method will be used in the following belt replacement instructions. A rule of thumb for checking belt tension by the deflection method is to determine the midpoint between two pulleys of the drive belt and press down at that point with moderate thumb pressure. The belt should deflect to the measurement indicated in the following installation procedures. Adjustment is necessary if the belt is either too loose or too tight.

WARNING A belt adjustment which is either too loose or too tight will eventually damage the accessory that belt is driving. A too loose adjustment allows free-play in the belt which could transfer a whipping motion or shock to the accessory drive pulley. Similarly, a belt which is too tight will preload the accessory bearings, leading to early failure.

REMOVAL & INSTALLATION

See Figure 11
Raise the front of the vehicle, support on jackstands and remove the lower splash shield if access is hampered due to space limitations when changing drive belts.

Timing belts are typically only used on overhead camshaft engines. Timing belts are used to synchronize the crankshaft with the camshaft, similar to a timing chain on an overhead valve (pushrod) engine. Unlike a timing belt, a timing chain will normally last the life of the engine without needing service or replacement. Timing belts use raised teeth to mesh with sprockets to operate the valvetrain of an overhead camshaft engine.

Whenever a vehicle with an unknown service history comes into your repair facility or is recently purchased, here are some points that should be asked to help prevent costly engine damage:

* Does the owner know if, or when the belt was replaced-
* If the vehicle purchased is used, or the condition and mileage of the last timing belt replacement are unknown, it is recommended to inspect, replace or at least inform the owner that the vehicle is equipped with a timing belt.
* Note the mileage of the vehicle. The average replacement interval for a timing belt is approximately 60,000 miles (96,000 km).


Inspection

Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately.

Removal & Installation

1. Raise and support the vehicle.
2. Remove the engine splash shield.
3. Rotate the drive belt tensioner clockwise to release the drive belt tension.
4. Remove the drive belt from the alternator.
5. Slowly release the drive belt tensioner.
6. Remove the drive belt from the accessory drive pulleys.

5. Slowly release the drive belt tensioner
6. Install the engine splash shield.
7. Lower the vehicle.

1998 Pontiac Sunfire Belt Routing Diagram

A drive belt routing diagram is needed when replacing a drive belt to help simplify the installation process. The problem arises as there are many different ways a drive belt can be configured. In this configuration the belt length will vary not allowing the belt to be installed. Also alternative configurations could turn a particular accessory the wrong direction, creating more problems. Always reinstall the drive belt in the exact configuration as the previous belt to prevent these problems. Always use high quality replacement products to avoid premature drive belt failure. If a multi rib drive belt fails it must be replaced immediately to avoid such situations such as engine overheating and loss of the power steering system. Whenever a belt replacement is required inspect the pulley condition to ensure there are no sharp edges on any of the pulleys, this will cause the belt to shred and fail. Confirm that all pulleys are free from debris such as small pebbles, these pebbles will cause the belt to pit and significantly impair the belt performance. The belt tensioner plays an important role to the drive belt performance, if this tensioner is weak it can allow the belt to lose tension allowing the belt to jump and skip. This condition will result in noises such as squeaking, chirping and ticking.

Drive Belt Replacement WARNING: IF EQUIPPED, DO NOT ALLOW DRIVE BELT TENSIONER (6B209) TO SNAP BACK AS DAMAGE TO DRIVE BELT TENSIONER OR PERSONAL INJURY COULD RESULT.
NOTE: Minor cracks in the V-grooved portion of the serpentine drive belt (8620) are considered normal and acceptable. If the drive belt has chunks missing from the ribs, the drive belt should be replaced.

NOTE: Conditions requiring drive belt replacement are excessive wear, rib chunk-out, severe glazing, frayed cords or other conditions. Replace any drive belt exhibiting any of these conditions.

NOTE: When installing drive belt on pulley, make sure that all V-grooves make proper contact with pulleys.
