Having problems with your Toyota Celica ?
Some kind of oil in coolant
\015 I just bought a 94 Celica St w/ auto trans and 117k mi. Today my daughter went to check fluids... and the fluid in the resevoir was nasty, so I took off the radiator cap and stuck my finger in there and the fluid was dark and felt oily. It runs great, runs cool. No smoke no smell. How do you tell what kind of oil it is? Engine or tranny fluid? I found records on the car and found that in 07 at 90k the coil and head gasket were replaced. could it be that oil made its way into the coolant when the gasket was bad and it just wasn't flushed, or could it be a bigger problem? Where do I start?\015
Drain all the coolant reverse flush the cooling system refill with antifreeze drive the car a few days check the radiator if it looks bad again your oil cooler in the radiator is leaking replace the radiator unless the head is warped or, the gasket was installed wrong (you would have a rough running car) the gasket should not be the problem however a garage can do a compression test to be sure
It is very possible that oil was spilled into the water jacket during head gasket change. Another possibility is that the trans cooler which is built into the rad has a crack in it. Check the trans level but it doesn't take much oil to show up like that. Best to remove the oil and see if it comes back. The oil has to be removed from the top. Draining the cooling system will not get the oil out. Good luck Moe
