This oil cooler assembly is located on the side of the engine block, typically near the oil filter. Its primary function is to use the engine's coolant to regulate and reduce the temperature of the engine oil. For a 4x4 owner with the legendary TD42 engine, maintaining optimal oil temperature is critical for engine longevity, especially under heavy-load conditions like towing, low-range crawling, or climbing steep inclines. Over time, the internal seals can perish or the unit can develop cracks, leading to failure and requiring a complete replacement to protect your engine.
The risk: Ignoring a faulty oil cooler can have catastrophic consequences. A common failure is an internal breach, causing coolant and oil to mix. Coolant in your oil drastically reduces its lubricating properties, leading to premature bearing wear and potentially a complete engine seizure. Oil in your cooling system can degrade rubber hoses and clog the radiator, leading to severe overheating. Either failure can leave you stranded and facing a very expensive engine rebuild.
