Oil in antifreeze

[d_crosson]

Just bought a 2000 grand am. There is oil in the antifreeze coolant and i cannot find the source, any ideas of what it might be?

Welcome to AF.

Sounds like a lower intake or head gaskets leaking.

Not good!

Are you sure it's oil and not just Dex cool sludge ?

Hope you bought a warranty, good luck

It could be sludge, unsure it looks like oil. This is the first car that i have ever had with dexcool. The only thing that doesn't work is the heater.

Heater could be a problem of the Dex sludge.

Probly could try a cooling system flush and some fresh coolant. Then see if any discolored coolant returns.

Good Luck
