radiator problems
The trans cooler in the radiator could be seeping some into the cooling system.
Your gonna need a radiator anyways if it is cracked.
This is an LS1 car right? if it is engine oil that will be a problem then, it would have to be internal engine if it is getting into the cooling system.
Unless it is an eary LT1 or other that has an internal radiator mounted oil cooler.
well that could be the issue right there. You very well could have some left over PS fluid in there. I would bet that is likely the issue.
Not a common problem to get engine oil into the coolant w/ out some pre-existing issue. overheating running problem etc.
Otherwise head gaskets are the most common to cause this.
Not always easy to find the problem if it is internal engine. The oil usually has to have some pressure behind it to get forced into the cooling system.
I would repair the radiator problem clean the cooling system as best as possible & keep a close eye on it.
Get a new radiator, its cracked.

It was tranny fluid. It gets dark and forms globs of it. It will stick inside your radiator cap too.
If you're radiator is cracked, you need a new one anyway. Get one and flush the coolant system BIG TIME to get it all out of the block.
