blown head gasket....not good.
Could b Transmission Fluid because the transmission cooler is in the radiator-especially IF the water has a red tint 2 it,IF it has a automatic transmission.
Does it have 2 lines coming from the top of the oil filter, and going to the radiator. If so that is the oil cooler. You need to replace the RADIATOR Those 2 lines go into the radiator so it can cool the oil, and the tubes are leaking oil into the coolant.
blown head gasket
Lack of coolant in the radiator. Fan not working. Not enough oil.
It Could Be a Bad Gasket that causes water to mix with coolant more than likely you will see white dough like substance in radiator.
The automatic transmission oil cooler is built into the radiator. If the oil cooler developes a leak the oil mixes with the engine coolant.
if this vehicle is automatic,the most likely cause would be the transmission fluid cooler. it is a tank inside the radiator that cools the transmission fluid. if by any reason the tank leaks it would contaminate your water/coolant/antifreeze. answer a cracked head will allow oil into water jacket in head, going from there thru to radiator if it was a bad head gasket, u would have water in oil instead
You may have a blown head gasket. Have it pressure tested. The head gasket keeps the cylinder head sealed from the water that circulates through the heads to keep them cool. If the gasket gets a hole in it, then there is a gap in which oil can get into your coolant. Make sure what you are seeing is OIL in the coolant first.
I would have to guess that your radiator has a hole in it. Look andd see if your transmission lines go to a tank on the radiator. If this is the case then the radiator will have to be replaced. You transmission line is leaking oil into the coolant. Is there also coolant in the transmission? This is the only way that I can see this happening. Now if you were just having coolant in the transmission then I would say that there was a head gasket issue. well I hope this helps you.
Oil and water do not mix. oil will float on top of coolant if you remove radiator cap this will be very visible, on the other hand coolant in oil will look milky white.
well, check your oil, engine coolant, and your radiator.
your radiator needs to be replaced
You are getting water into the coolant. Most likely cause is a failed radiator/oil cooler. If the coolant level keeps reducing and transmission oil level keeps increasing then the above answer is correct.
