Note. Proper adjustment of the tension of the drive belts helps to avoid slippage, while not overloading the bearings of the serviced units, which is especially important in the case of a generator and a water pump.
Scheme of laying drive belts on models with a 3.0 l engine
1 - fan / water pump pulley; 2 - air conditioner compressor pulley; 3 - steering pump pulley; 4 - tension roller; 5 - crankshaft pulley; 6 - generator; A = fan belt,; B = steering pump drive belt,; C = air conditioning compressor drive belt
Laying of belts on the engine 4.2 l
1 - generator pulley; 2 - fan pulley; 3 - tension roller; 4 - steering pump pulley; 5 - air conditioner compressor pulley; 6 - crankshaft pulley; A = fan belt,; B = steering pump drive belt,; C = air conditioning compressor drive belt
Fan belt (belts)
1. Press down on the fan belt (belts) in the area in the middle between the pulleys of the generator and the water pump with a force of 98 N (thumb force). The required belt deflection is 4÷8 mm for 3.0 l models and 13÷15 mm for 4.2 l models.
Note. Be sure to replace belts on 4.2 l models as a set.
2. If necessary, loosen the generator stop bolt and turn the adjusting bolt to achieve the required belt tension (by deflection).
3. Tighten the alternator retaining bolt, run the engine for approximately five minutes, and recheck the correct belt tension.
Steering pump drive belt
1. Press on the drive belt in the area in the middle between the pulleys of the steering pump and the crankshaft with a force of 98 N (thumb force). The required belt deflection is 11 ÷ 15 mm for 3.0 l models and 15 ÷ 17 mm for 4.2 l models.
2. If necessary, loosen the steering pump stop bolt and turn the adjusting bolt to achieve the correct belt tension (by deflection).
3. Tighten the steering pump stop bolt, run the engine for about five minutes, and recheck the belt tension.
Air Conditioning Compressor Drive Belt
1. Press the belt in the area in the middle between the pulleys of the air conditioning compressor and the crankshaft with a force of 98 N (thumb force). The required belt deflection is 6 ÷ 10 mm for 3.0 l models and 8 ÷ 10 mm for 4.2 l models.
2. If necessary, loosen the clamping nut in the center of the tension roller and turn the adjusting bolt to achieve the correct belt tension (by deflection).
3. Tighten the idler lock nut, run the engine for about five minutes, and recheck the belt tension.
