Note: A description of how to check the condition and adjust the tension of the accessory drive belts is given in Section Checking the condition of the auxiliary drive belt and adjusting its tension.
Intermediate Roller Installation Components
1 - Water pump drive belt adjusting bolt; 2 - Assembling the intermediate roller; 3 - Axis; 4, 7 - Cover; 5 - Bushing; 6 - Intermediate pulley; 8 - Bracket; 9 - Adjusting bolt of the generator and compressor drive belt
1. Completely loosen each belt (see section Checking the condition of the auxiliary drive belt and adjusting its tension) and remove the belts, starting from the front.
Note: If the belt is not being removed for replacement, mark the direction of travel on the belt.
2. The components for installing the belt idler rollers are shown in the illustration above.
3. To remove the intermediate pulley of the alternator and compressor drive belt, remove the adjusting bolt from the pulley axle, slide the pulley along the groove on the bracket and remove it by turning the end of the axle on the wide part of the groove.
4. To remove the water pump drive belt idler pulley, loosen the lock nut and remove the axle by pulling it towards the rear of the engine.
5. Installation of pulleys is carried out in reverse order.
6. Make sure that both the belts and pulleys are free of grease, oil or coolant and install the belts. If installing a previously used belt, observe the direction of its rotation.
7. Make sure the belts are correctly positioned in the pulley grooves.
8. Rotate the crankshaft at least two revolutions to equalize the belt tension between the various pulleys. Check and adjust the belt tension if necessary (see section Checking the condition of the auxiliary drive belt and adjusting its tension).
