🔌 Function

Passes hot oil through a core swept by coolant or raw water, carrying heat away so oil viscosity and film strength stay within limits under load.

⚠️ Common Signs of Failure

• Oil temperature running high, or the gear oil alarm sounding under load
• Oil in the coolant, or coolant milkiness in the oil
• Weeping or salt crust around the end tanks and unions
• Sluggish gearchange or slipping as hot oil thins out
• Corroded or blocked core with poor flow through it

🛠️ Service Notes

• Confirm the engine or gear application and the port layout against your engine serial number before ordering
• A cooler that has leaked internally contaminates both circuits - flush the oil side and the coolant side before running the new unit
• Renew the union seals and check the hoses feeding it at the same time

📦 Condition
