What This Product Does

This radiator forms part of the engine oil cooling circuit. Heat passes out through the cooler, helping control the temperature of the oil used to lubricate internal engine components. The cooler works alongside the oil lines, thermostat and associated cooling hardware.

Functions

• Transfers excess heat away from engine oil.
• Supports oil temperature management during operation.
• Helps maintain suitable conditions for engine lubrication.

Why Replacement Matters

A leaking or damaged cooler can compromise oil temperature control and allow oil loss. Renewing a confirmed faulty unit addresses the damaged component, but adjoining pipes, unions, seals and mountings should also be inspected. Establish whether leakage originates from the cooler itself or a nearby connection before replacement.

FAQs

Does high oil temperature prove the cooler has failed?
No. Oil level, thermostat operation and airflow can also affect temperature, so diagnosis should cover the wider system.

What should be inspected during replacement?
Check the connected oil lines, sealing points, mounting rubbers and surrounding airflow path for deterioration or damage.

How can a suspected leak be confirmed?
Inspect the cooler and its connections to locate the source; appropriate pressure testing can help confirm leakage.
