My 06 Chrysler 300 had oil going into the radiator. The shop is telling me the engine is holding pressure and are ruling out a blown head gasket. Also said the oil cooler is holding pressure as well. What else could cause this problem?

Asked by Sep 04, 2015 at 11:09 PM about the 2006 Chrysler 300 Limited

Question type: Maintenance & Repair

Oil mixing with coolant.  Engine did not run hot nor was there any thick smoke from the exhaust.  Engine and oil cooler are holding pressure.  What would cause this problem?

Automatic transmission fluid. If you have a transmission fluid cooler in the radiator (most automatics do) it's probably leaking. The "oil" that your seeing is most likely automatic transmission fluid. HTH. -Jim
