to set the number 1 cylinder to compression top dead center.

2. If the timing belt is to be reused, chalk mark the flat side of 

the belt with an arrow indicating the clockwise direction.

3. Loosen the center bolt of the tension pulley, and then 

remove the timing belt.

INSTALLATION SERVICE POINTS

.

>>A<< TIMING BELT INSTALLATION
1. Align the timing marks of the camshaft sprocket with those 

of crankshaft sprocket.

CAUTION

The camshaft sprocket (right bank) can turn easily due to 
the spring force applied, so be careful not to get your fin-
gers caught.
2. Install the timing belt by the following procedure so that 

there is no deflection in the timing belt between each 
sprocket and pulley.

(1) Crankshaft sprocket
(2) Idler pulley
(3) Camshaft sprocket (Left bank)
(4) Water pump pulley
