Chrysler: Set phasers to stun

A “small number” of 2011 Chryslers equipped with the 3.6L engine, built between March 5, 2011, and April 1, 2011, may feature improperly torqued camshaft phaser oil control valves. Vehicles that have engines with loose oil control valves (improperly torqued) must have their engines replaced.

According to Chrysler, this service action applies to specific unsold vehicles (at this point, vehicles in overstock).

If either oil control valve is loose, the engine must be replaced. According to the TSB, once the engine has been replaced, the vehicle must be diverted to auction with full disclosure.

INSPECTION PROCEDURE

1. Disconnect and isolate the negative battery cable.

2. Remove the right cylinder head cover.

3. Once the valvetrain is exposed, rotate the crankshaft clockwise by wrenching on the damper bolt until the two datum holes in the camshaft (Fig. 1) are pointing straight up.

4. Verify that number one piston is at TDC on the exhaust stroke. The right side camshaft phaser arrows should point away from each other and the scribe lines should be parallel to the valve cover sealing surface (Fig. 2).

5. Verify that the oil control valve is set to the proper torque by securing the camshaft on the cast flats with an open end wrench and torquing the oil control valve to 110 ft.-lbs. Repeat on the other camshaft.

6. If the oil control valve was properly torqued, proceed to the next step. If either oil control valve is loose, the engine MUST be replaced.

7. Install the right side cylinder head cover.

8. Reconnect the battery negative cable.
