1.5.5.4. Replacement of an auxiliary belt on 6-cylinder DOHC engines

Models with the index of the regulator of a tension

Arrangement of a plastic casing
 The arrow specified that which needs to be removed for access to a bolt of fastening of the mechanism of a tension of the 6-cylinder DOHC engine with the index of the regulator of a tension.

Weakening of a bolt of fastening of the mechanism of a tension of a driving belt on the 6-cylinder DOHC engine with the index of the regulator of a tension

 

Unscrewing of a nut of the regulator of an auxiliary driving belt on the 6-cylinder DOHC engine

 

Arrangement of an auxiliary driving belt on the 6-cylinder DOHC engine
The sequence of installation of an auxiliary driving belt on pulleys:
1 – tension mechanism pulley;
2 – pulley of a bent shaft;
3 – pulley of the compressor of the air conditioning system;
4 – single pulley;
5 – radiator fan pulley;		 6 – pulley of the air fuel pump;
7 – generator pulley;
8 – single pulley;
9 – pulley of the pump of the amplifier of steering;
10 – pulley of the water pump

PERFORMANCE ORDER
1. Remove a krylchatka of the fan of a radiator and a casing.
2. Weaken a bolt of fastening of the mechanism of a tension on a quarter of a turn (see rice. An arrangement of a plastic casing, Weakening of a bolt of fastening of the mechanism of a tension of a driving belt on the 6-cylinder DOHC engine with the index of the regulator of a tension).
3. Unscrew counterclockwise a nut of the regulator and unscrew the regulator so that the belt was completely weakened. Take off a belt from pulleys (see rice. Unscrewing of a nut of the regulator of an auxiliary driving belt on the 6-cylinder DOHC engine).
4. Establish a new auxiliary driving belt on pulleys, since a single pulley and in the sequence shown in the drawing Arrangement of an Auxiliary Driving Belt on the 6-cylinder DOHC engine.
5. Adjust a tension of an auxiliary driving belt as follows.
6. Move the index of the mechanism of a tension before combination of a tip of the index with the right narrowest end of a triangle on a large-scale ruler.
7. Turn a regulator nut clockwise until the tip of the index of the mechanism of a tension is combined with the thick line on a large-scale ruler (see rice. The mechanism of adjustment of a tension of an auxiliary driving belt on the 6-cylinder SOHC engine).
8. Tighten a bolt of fastening of the mechanism of a tension the required moment.
9. Establish a krylchatka of the fan of a radiator and a casing.

Models with the automatic regulator

Reduction of a tension of an auxiliary driving belt
 
For reduction of a tension of an auxiliary driving belt on 6-cylinder DOHC engines establish a wrench on a nut of a pulley of the mechanism of a tension (1) and turn a wrench clockwise.

PERFORMANCE ORDER
1. Remove a krylchatka of the fan of a radiator and a casing.
2. Establish a wrench in the center of a pulley of the mechanism of a tension and for a wrench turn the tension mechanism clockwise therefore the tension of an auxiliary driving belt (see rice will decrease. Reduction of a tension of an auxiliary driving belt).
3. Enshrine the tension mechanism in this provision by a wrench and take off an auxiliary driving belt from pulleys.
4. Establish a new auxiliary driving belt on pulleys, since a single pulley and further in the sequence shown in the drawing Arrangement of an Auxiliary Driving Belt on the 6-cylinder DOHC engine.
5. Release the wrench holding the tension mechanism therefore the mechanism of a tension will turn and there will be a tension of an auxiliary driving belt.
6. Establish a krylchatka of the fan and a casing.
