Removal Procedure
7. Install a 24 mm wrench on the hex on the exhaust camshaft in order to hold the camshaft.
13. Install a 24 mm wrench on the hex on the intake camshaft in order to hold the camshaft.
Installation Procedure
1. If replacing the balance shaft timing chain, perform the following steps, if not proceed to step 11.
11. On 2.4L engines, ensure the intake camshaft notch is in the 5 o'clock position (2) and the exhaust camshaft notch is in the 7 o'clock position (1). The number 1 piston should be at TDC, crankshaft key at 12 o'clock.
12. Install the timing chain drive sprocket to the crankshaft with the timing mark in the 5 o'clock position and the front of the sprocket facing out.
Note:
* There are 3 colored links on the timing chain. Two links are of matching color, and 1 link is of a unique color. Use the following procedure to line up the links with the actuators. Orient the chain so that the colored links are visible.
* Always use new actuator bolts.
13. Assemble the intake camshaft actuator into the timing chain with the timing mark lined up with the uniquely colored link (1).
17. Route the timing chain around the crankshaft sprocket and line up the first matching colored link with the timing mark on the crankshaft sprocket, in approximately the 5 o'clock position.
20. Install the exhaust camshaft actuator into the timing chain with the timing mark lined up with the second matching colored link.
21. Install the exhaust camshaft actuator onto the exhaust camshaft, aligning the dowel pin into the camshaft slot.
22. Using a 23 mm open end wrench, rotate the exhaust camshaft approximately 45 degrees until the dowel pin in the camshaft actuator goes into the camshaft slot.
24. Verify that all of the colored links and the appropriate timing marks are still aligned. If they are not aligned, repeat the portion of the procedure necessary to align the timing marks.
