When checking your oil, please pay attention to its color and texture. Upon getting to engine oil, the coolant dilutes the oil such that a creamy coffee color forms as a testament to the oil losing its lubricating powers due to the contamination. ![]() If you notice that your oil has a creamy coffee color, you have a coolant-oil mixture in your oil sump that needs immediate addressing. Oil is originally an amber or deep yellow color, and any other color for oil indicates a problem. There are five main ways you can use to detect if your oil has coolant in it. How do you know your oil has coolant in it? Coolant mixed in oil causes this effect which can eventually cause engine failure. The engine cannot work with a non-lubricating liquid that increases instead of decreasing the heat from the engine. Coolant mixing with the oil will reduce oil quality and gradually take over if not checked on time. Since metal is an essential engine component, it requires oil to keep its parts going without generating too much heat. When coolant enters oil, it can lead to engine failure. So, what happens when the coolant gets into the oil? The composition of coolant and oil are entirely different in terms of function. An engine without oil would degrade fast. It protects the engine from freezing (antifreeze) and aids against corrosion.Ĭonversely, oil is a viscous lubricant that keeps the engine cool while reducing friction. What does coolant do to oil?Ĭoolants are less viscous, non-toxic, chemically inert, and highly thermal liquids (or gas) used to maintain an engine’s heat balance. This article explains how and why coolant can get into the oil and what to do about it. It would help if your auto mechanic checks it it could indicate a bigger problem. The first thing you would have to do is to clean the reservoir before flushing the radiator and changing the oil. So what do you do when you see coolant in the oil? However, there are instances where you find coolant in the oil sump. You should not see so many things in your oil sump besides oil. see if it's low or milky.What do you do if your oil sump is something else other than oil? In the beginning, the oil sump contains only oil and over time, a buildup of dirt can occur above it (in the oil filter) when it passes through the sump without proper maintenance. I give this a almost completely unlikely chance but stranger things have happened.Ī side note: you may also want to check your trans fluid if it's an automatic. If it is not your radiator the only other place that higher pressure oil and water could mix is by a very strange crack in the block that only goes between a high pressure oil spot and somewhere that there is coolant. I am pretty confident it is your radiator though. If you want to go crazy you can hook up some test line to the oil inlet, plug the outlet, hook up some compressed air, and see if you hear hissing inside the radiator. ![]() Thoroughly check for any cracks or damage around the fittings on the radiator. This is also the only point where they are close to mix if there was a break and has potentially higher oil pressures than the coolant pressure. Both the engine oil and trans oil passing through the radiator should be higher pressure than the water which is good news for you, there shouldn't be water in places it can damage, oil in water doesn't do much. ![]() The radiator on these are a single unit containing the engine cooler and a transmission cooler, if you have an automatic transmission. If the head gasket was blown you would get the classic water in oil and not oil in water. This engine is a single in block cam engine so there should be no high pressure oil going to the heads across the head gasket.
