🔌 Function

Passes engine oil across a cooling circuit to hold oil temperature down, protecting the oil film under sustained load.

⚠️ Common Signs of Failure

• Oil temperature high and oil pressure falling when hot
• Oil in the coolant or coolant in the oil, giving a milky emulsion
• Weeping or salt crusting around the end covers
• Cooler silted or furred internally so it no longer sheds heat
• Unexplained coolant loss with nothing visible outside

🛠️ Service Notes

• Pressure test before condemning it, since oil and coolant can mix elsewhere on the engine
• Renew every end cover seal and o-ring when the cooler is opened
• Change the oil and filter after any internal cross-contamination
