on the top of the radiator i got the quick connect line off, but i am having a really hard time unbolting the fitting in the radiator. it feels like i am going to break it, is this just really hard to undo, or am i actually going to break it? please help

 

It's definitely tight...you should use a line wrench or good crow's foot to help prevent rounding the edges of the fitting. You could hit it with a little rust penetrant also...

...the aluminum colored fitting that is in the radiator (after removing the upper cooler line), stays in the radiator and a fitting goes into that for the auxilary cooler.

 

i got it, it was just really tight.
