Timing Chain Tensioner Replacement

Tools Required

J 44221 Camshaft Holding Tool

Removal Procedure

1. Remove the camshaft cover.
2. Remove the engine front cover.




3. Rotate the crankshaft in the engine rotational direction clockwise, until the #1 piston is at top dead center (TDC) on the compression stroke.
The word Delphi on the exhaust camshaft position actuator will be parallel with the cylinder head to cam cover mating surface.




Caution: Refer to Camshaft Holding Tool Caution.

4. Install the J 44221 to the rear of the camshafts.




5. Using the timing marks on the following as a reference, make a mark on the timing chain links (1) adjacent to them:
^ The exhaust camshaft position actuator sprocket
^ The Intake camshaft sprocket
^ The crankshaft sprocket




6. Release the tension on the timing chain by moving the tensioner shoe in.




7. Place the tee into the tensioner to hold the shoe in place.




8. Remove the timing chain tensioner bolts.
9. Remove the timing chain tensioner from the engine.

Installation Procedure




1. Position the timing chain tensioner to the engine.

Notice: Refer to Fastener Notice.

2. Install the timing chain tensioner bolts.

Tighten the bolts to 25 N.m (18 lb ft).




3. Remove the tee in the timing chain tensioner in order to regain tension on the timing chain.




4. Remove the J 44221 from the camshafts.





Important: Every 7th link of the timing chain is darkened to aid in aligning the timing marks.

5. Align the marked links (1) on the timing chain with the timing marks on the following:
^ The exhaust camshaft position actuator sprocket
^ The Intake camshaft sprocket
^ The crankshaft sprocket
6. Install the engine front cover.
7. Install the camshaft cover.
