🔌 Function

Passes engine oil through a coolant-cooled core to hold oil temperature and viscosity in range.

⚠️ Common Signs of Failure

• Oil in the coolant or coolant in the oil - a milky dipstick or an oily header tank
• Oil temperature and pressure both drifting under sustained load
• External weeping at the cooler joints or end caps
• Core silted or scaled, so the engine only runs hot when working hard
• Coolant loss with no external leak found anywhere else

🛠️ Service Notes

• A cooler that has passed oil into the coolant means the whole circuit needs flushing before the new one goes on
• Renew the cooler seals and gaskets as a set, and check the oil for bearing debris if the old core was blocked
