Other signs that the oil cooler isn’t working properly include a loss in engine power, a misfiring engine, a rise in engine temperature and an increase in dark exhaust emissions. If the owner has missed these symptoms, the car may have overheated. In the early stages of a leak, there may just be an oily sheen on top of the coolant. But do be on the lookout for any of the aforementioned abnormalities. The Main Symptom of Oil in the Coolant The most common visual symptom of a leak that has been going on for a while is a brown milky sludge in the coolant. Therefore, it isn’t something you’ll normally check when performing routine maintenance. Once again, you’re looking at engine damage, due to a lack of lubrication.Īn oil cooler should last as long as your engine or as long as your car. This problem occurs when a bad oil cooler raises oil pressure higher than cooling system pressure, forcing oil into the cooling system. Just as you don’t want coolant mixing with oil in your engine, you never want to find oil in the cooling system. Although less common, a bad oil cooler can also cause coolant to contaminate engine oil, leading to engine damage. GM’s L81 3.0L V6 engine actually tucked the oil cooler down in the engine block where it was surrounded by coolant, and was notorious for allowing coolant to leak into the oiling system when it failed. OIL IN COOLANT CRACKEDWhen coolant enters the engine and mixes with oil, we usually attribute this problem to cracked or warped cylinder heads or blown head gaskets. If the leak is significant, you’ll notice coolant on the ground or see steam gushing out from underneath the hood. When an oil cooler fails, it can force all the coolant out of the engine and raise the risk of an overheated engine, which may lead to possible engine damage. ![]() Coolant flows through (or around) the coils or tubes, but has no contact with the oil. Some oil coolers use coolant (antifreeze) to keep the oil temperature regulated. When the problem is a bad oil cooler, oil will puddle on the ground. Check your oil filter housing as well because the oil filter housing has a one peice gasket for coolant and oil, if this gasket is bad enough it can cause the. Another place to look is the oil cooler adapter, which connects oil lines and is itself sealed with a gasket. Most oil leaks stem from bad connections or cracked oil pans, engine gaskets or seals. The following signs indicate that a potentially serious problem is underway. A failing or bad oil cooler is never a good thing. This unit cools the oil as it passes through coils (or stacked plates). Some designs are tied in with the engine’s cooling system, while others use the outside air like a radiator. A working oil cooler is essential to the operation of a car’s engine, as it’s tasked with maintaining motor oil within its optimal lubricating temperature range. ![]()
