RESETTING CAM CHAIN TENSIONER
The cam chain tensioner used on the 2.0L engine is equipped with a ratchet. The ratchet consists of a pawl (1) and a rack (2). The rack (2) is part of the piston (3) and a ratchet arm (4) is attached to the pawl (1). In use, an internal spring extends the piston (3) from the tensioner body. The pawl (1) will not allow the piston (3) to retract back into the tensioner body. In order to reset the tensioner, the pawl (1) must be disengaged from the rack (2) so that the piston (3) can be pushed back into the tensioner body.

Note. The hole (2) in the ratchet arm (4) provides an anchor point for a pin (1/8 in. drill bit) that locks the pawl against the rack to hold the piston in the retracted position. But, the holes (2 and 3) will not align when the piston is fully retracted. The piston must be allowed to extend at least "three clicks" from the fully retracted position before the holes will align.
- Use a 1/8 in. drill bit to rotate and hold the ratchet arm (4) counterclockwise to lift the pawl off of the rack.
- Push and hold the piston (1) into the tensioner body. NOTE: If the engine front cover is installed, use the timing chain to push and hold the piston into the tensioner body by slightly rotating the intake camshaft (1) clockwise.
- Continue holding the piston into the tensioner body and release the ratchet arm.
- Allow the piston (1) to extend slightly until the hole in the ratchet arm (3) aligns with the hole in the tensioner body. When the holes are aligned, insert the 1/8 in. drill bit (2) to lock the pawl against the rack which will hold the piston in the retracted position.
