What Impact Does a Faulty Oil Cooler Have on the Engine?

[MacJudah]

If the oil cooler is damaged, it can lead to excessively high oil temperatures, which will affect the engine's lubrication and normal operation. Below is relevant information: 1. Common failures in water-cooled oil coolers include copper pipe ruptures, cracks in the front/rear covers, seal damage, and internal blockages in the copper pipes. Copper pipe ruptures and cracks in the front and rear covers are often caused by operators failing to drain the cooling water from the diesel engine block during winter. 2. When the above components are damaged, it can result in oil entering the water cooler and coolant mixing with the oil in the oil pan during diesel engine operation. If the oil pressure exceeds the coolant pressure while the diesel engine is running, oil can leak through holes in the core into the coolant, circulating with the coolant and entering the water cooler.
