An engine Oil leak may develop at the cam sensor o-ring seal. Our technicians tell us this is often misdiagnosed as an external head gasket leak.

If a Check Engine Light illuminates indicating leak detection pump (LDP) failure, the cause is often pinched or disconnected vacuum lines to the pump. Vacuum lines should be inspected before replacing the leak detection pump. Contamination (carbon or debris) in the pump can cause failure and any hoses should be cleared before a new pump is installed.

The radiator cooling fan may fail to turn on resulting in an engine overheating condition, or The fan may not turn off once it is on. Chrysler has released a service bulletin to address this issue. The repair involves install a jumper wire harness and new cooling fan relay.

When the trunk lid weatherstrip (seal) is worn, the lid may rattle, water may leak into the trunk, or dust may get into the trunk. After installing a new trunk lid (deck lid) weatherstrip, be sure to adjust the trunk slam bumpers so the power trunk latch opens the trunk on the first attempt.
