Oil in the radiator expansion tank can be caused by a blown head gasket, which allows engine oil to mix with coolant. Another possibility is a cracked engine block or cylinder head, creating a pathway for oil to enter the cooling system. Additionally, a failing oil cooler, if equipped, can leak oil into the coolant. These issues typically indicate serious engine problems that require immediate attention.
Front corner of the engine - passenger side, right near the radiator expansion tank and radiator cap.
either the transmission oil line to radiater is not tightene or the oil cooler tank at bottom of radiator has a leak
Yes. The engine oil cooler is in the drivers side tank and transmission oil cooler is in the passenger side tank of the radiator.
The AT oil cooler is in the bottom tank of the radiator. If you are seeing oil leaking from one of the lines from and to the transmission connection could be loose.
Its either leaking it, burning it or blowing it into the water jacket. Look for puddles under, blue smoke out the back or off-white scum in the radiator expansion tank.
Not much actually.
usually a head gasket
it`s in the radiator (notice two large lines on passenger side radiator tank)
If the car has a transmission cooler in the side tank of the radiator, yes. This set up is very common.
If is oil then you have a bad intake manifold gasket. If it is transmission fluid then the cooling tank in the radiator is bad.
The thermal Fluid expansion tank is used to heat naphthenic fluid which is FDA approved to heat the vegetable oil that they use to cook their kettle chips amoungst other snack foods.
Sure you can drive it but, you need to ask yourself, why is there oil in the radiator? If you did not pour oil in the radiator then you have a problem. Most likely cause is a blown head gasket. This is extremely serious, and will destroy the engine if not repaired.
