Oil cools and lubricates your engine’s crankshaft, bearings, pistons, connecting rods, and camshaft. The purpose of the oil cooler is to keep the oil at a temperature of between 82°C and 93°C – the level at which it works best. The longer the oil stays at this temperature, the longer your engine and gearbox will last. Bad or failing air coolers and pipes may result in your engine overheating and suffering from excessive friction. This in turn could lead to severe damage. If you notice any oil or coolant leaks, check your pipes and cooler and replace any damaged items at once. For high quality oil coolers and pipes, you can be sure to find just what you need at Euro Car Parts.
