The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
CONDITION/CONCERN:
Some 2003 thru 2007 9-3's with 4 cylinder engines are experiencing coolant loss with no evidence of leakage found. Engineering suspects a possible porosity problem with the block castings.
RECOMMENDATION/INSTRUCTIONS:
Ensure the following proper diagnostic steps have been completed, including installing dye in cooling system, pressure testing, then driving and tracking any loss of coolant. Also check for coolant leaking into the transmission from the transmission cooler in the radiator. If the technician still cannot locate leak remove head to check to for any residual metal from the machining process that may have become trapped between the head and the block. If no issues with head gasket sealing are found, have head pressure tested. If coolant loss has been documented and no leaks are found, the short block may need to be replaced. Please make note of engine serial numbers.
A reinforced block has entered production from the VIN's below, which greatly reduced the likelihood of this issue.
