This PI was superseded to update parts information. Please discard PIP3851.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Originally, the vehicles above were equipped with an engine oil cooler at the start of 2006 model year production. However, validation tests demonstrated that an oil cooler is not required, even during extreme operating conditions. As a result, vehicles produced later in the model year are not equipped with an oil cooler. This eliminates a potential leak source, reduces the complexity, and reduces the cost of ownership.

Currently, the parts catalog lists a first design engine (12600671 - Oil Cooler) and a second design engine (12607337 - Without Oil Cooler). If a first design engine is stocked in SPO, the rest of this PI does not apply because a first design engine will be received so it can be installed in the vehicle without modifying anything.

However, if a first design engine is not stocked in SPO, it will be necessary to replace the first design engine with a second design engine by following instructions below.

If it is necessary to replace a first design engine with a second design engine:

1. Order the necessary installation kit from the list below:

•	89060544 - 2006 Cobalt/Pursuit

•	89060545 - 2006 HHR

•	89060546 - 2006 Solstice

•	89060547 - 2006 G6

•	89060548 - 2006 Ion

2. The kit should come with installation instructions but just in case they are missing or misplaced, install the kit by following the necessary installations instructions:

2006 Cobalt/Pursuit

2006 HHR

2006 Solstice

2006 G6

2006 Ion

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
