Default Oil leak fixed... Now leaking coolant

I had an issue a week ago where when I first started up my 96GT, it would pour oil out of the pin hole in the oil cooler. After doing some research I read it was caused by the o-ring on the oil filter adaptor going to crap. I pulled the adaptor off of the cooler and replaced the o-ring and it stopped the oil leak.

Now the issue is, where it was leaking oil from before, it is now leaking coolant. It is not leaking very bad, but bad enough to **** me off. Is there another o-ring/gasket that could need to be replaced or do I need a whole new cooler?

Did you change the gasket out on the oil filter adapter plate? Coolant and oil both flow through that thing, if you didn't change the gasket out, then that could be your problem.

Yeah all I changed was the o-ring on the oil filter adaptor. I guess I will have to tear the whole thing off and replace all the gaskets and see if that fixes it. Thanks for the help.
