Three. Engine nameplate 
The engine serial number is located on 
the lower cylinder body of the intake 
manifold.  
 
 
 
 
 
 
 
 
 
 
 
Four. Transmission belt 
1. Location of the transmission belt 
 
1-Engine 
2-Water pump/power steering pump 
3-Compressor 
4-Idle wheel 
5-Crank shaft 
6-Tensioner 
 
 
2. Unfixing and replacing the 
transmission belt 
It is important to adjust the tension of the 
transmission belt in the case of 
replacement or adjustment of engine 
transmission belt. Overtension of the 
transmission belt will result in damaged 
AC generator and wheel bearing of the 
power steering pump belt while 
undertension will result in skidding or 
early abrasion.  
Reel the transmission belt on the belt 
wheel in a proper manner for 
replacement. Notice the reeling path of 
the transmission belt before its 
replacement.  
1) Insert the tie-in of a pair of quick 
spanners into the belt tensioner.

2) Apply a torque of 98N (221bf) onto 
the middle of the belt tensioner until it 
caves in for 9.0 -11.5mm (0.35-0.45in). 
3) Press down the quick spanner in a 
reverse direction, release the tensioner 
and take out the old transmission belt.  
4) Pay attention to the belt’s reeling 
direction during fixing, press down the 
quick spanner in a reverse direction and 
fix the transmission belt.  
 
 
 
 
 
 
 
5) Release the tensioner and check if the 
belt is properly located.  
 
 
 
 
 
 
 
 
 
 
Note: Adjustment method for the 
alignment of the transmission belt and 
tensioner assembly.  
- Turn the engine crank shaft’s belt 
wheel with a pair of spanners for over 
one round.  
- Observe the alignment of the 
transmission belt and tensioner assembly. 
If the center of transmission belt goes 
beyond the center of the tensioner 
assembly, unfix the latter and insert 
gasket to adjust.
