Why do I have oil in my radiator?
I found this image in which it looks like the oil cooler is incorporated into the radiator on the left hand (driver’s side). You probably need to replace the head gaskets. The oil pump when functioning properly makes much more pressure than the coolant system. As a result, when the head gasket fails, oil can make its way into the coolant system.
Why is the coolant in my oil cooler not working?
Coolant in the oil When the engine is not running and the cooling system is pressurized, coolant can be forced from the cooling system into the oil pan. High oil pan levels can damage the engine by the crankshaft slapping the oil as it rotates.
Is it OK to put Trans Oil in the radiator?
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.
What causes oil to mix with coolant in car?
Sometimes a gasket or a crack could occur inside the oil cooler and it will cause the oil and coolant to mix up. This part is often much easier to replace and cheaper than a head gasket. It’s also a very common problem so I recommend checking the oil cooler if you have one fitted to your vehicle.
Can a radiator leak oil but not coolant?
Yes, oil can leak into the cooling system but that does not mean coolant will necessarily simultaneously leak into the oil. For example, if you have an oil cooler inside your radiator and that starts to leak, you will find oil in coolant but not necessarily any coolant in oil. This happened to me recently on my ’94 Suburban.
What causes a 7.3L diesel engine to overheat?
7) Ford 7.3 Power Stroke Diesel Overheating Overheating is a general issue the 7.3L Ford Power Stroke engine runs into. This could be related to the radiator, thermostat, water pump, cooling fan or bad coolant. Signs of overheating should be easy to pick up on.
Why does my car have oil in the coolant?
Had a shop replace the thermostat. They said that when they bled the coolant, it had oil in it, indicating a possible head gasket/intake gasket leak. Engine oil looks good, no sign of contamination. No smoke from the exhaust. It’s not using any oil or coolant. No ticks or knocks. No overheating.
What to do if you have oil in your coolant tank?
There is an easy way to test out if there is a leak in the oil or coolant system. The easiest way is to put pressure on the coolant system and see if it’s pouring out into the oil pan. To do this, you need a coolant pressure tool for the coolant system with the right adapter for your coolant expansion tank.
