Inorder to replace the engine oil cooler,you must have a lot of mechanical expertize. Must pull the top of the engine apart.Air box,injector rails,drivers side exaust manifold unless you are very mechanical,seek a pro (note) this job could cost between 650.00 to 1200.00 depending on who does it. Wish You Luck. There are more cateras in junkyards because of misdiognosis of this problem.most mechanics will say you need a engine!!! If you have a pull your own part get it from a 2000,2001 year they had a lot of these and changed the thickness of material in them or type of same.also you can practice pulling it apart before you do yours.

I bought a 1997 Cadillac Catera and the oil is milky looking. I am told it could be the head gasket. However it runs very rough and acts like it wants to blow up when pushed past 45mph. car not smokin


You should not be running it like that. The problem is the engine coolant is leaking into the oil. There is no doubt about that .The cause is a failed head gasket , cracked head or cylinder. You running the engine like that are putting bad oil into places that it is not supposed to be. Besides rust and overflow, you will cause excess wear.

Oil cooler under the intake plenum at rear top of engine is either bad or the gasket is gone. If you take oil filler cap off, you will see the paste on the cap. Are you going through coolant every so often?


Same as on my wife's 01.

1998 Cadillac Catera can't tell if it is the engine oil cooler or a headgasket but oil is mixing with coolant and coolant and oil, what would be a sign if it is engine oil cooler


If you have a head gasket problem, you should see dense white smoke coming out of the exhaust pipe if you have antifreeze (ethylene glycol) in the cooling system, especially right after starting the engine.

My 2000 Cadillac Catera is has water mixed with


it is normal to have that paste stuff on the underside of your oil cap and some on the tube the cap goes on. this is condensation it goes to the highest points in the engine alot of short trips makes this worse
if the oil thats drained out looks like regular dirty old oil then dont worry about it
if it looks pastie white then you got trouble

Is it Oil,or Automatic transmission fluid?
I've changed several Catera Radiator's because the transmission cooler cracked inside of them!!
Better check the transmission fluid for engine coolant too,Coolant in the Automatic Transmission will kill it purdy Quick!

Where are the hoses that run to radiator to cooling system located? send diagram. Oil went into water tank on 1998 cadillac catera


I don't have a diagram, but your problem is the oil cooler underneath the intake on top of the engine. Remove the intake, and the cooler is right there in between the heads. Easy to change once you get the intake off. This is a VERY common problem on Cateras, and the symptom of it is oil in your coolant. I have a 1998 Catera and had the same issue.

All Cateras run hot, comes with the car. I have been experiencing the same problem with mine. Although I believe that my thermostat is faulty. They had many problems dealing with the cooling system because of the whole dex cool issue but Check the thermostat to make sure it is opening and the test the heat sensor to ensure continunity. If you get past that you got me.

Car leaking coolant


First of all ensure that your car is leaking coolant fluid, and what is dripping is not just water condensation from the air conditioner.
If you have a coolant liquid leak, it can be from one of the ducts leading to radiator , from water pump or radiator itself. Check liquid levels, and if you have a leak have the car inspected by a qualified mechanic.
A broken water pump, for example, can cause your motor to blow in few miles.
