Thanks for the tips guys. I think I might end up getting the 1 -1/16 wrench too.

I've been researching this for ages since I knew the job had to be done. I would prefer to not strip any threads off the cooler.

I know judging by the other problems I've had with the car that the hoses will not come off without a fight. I've been soaking them with PB for awhile, but I'll start using liquid wrench instead.

I think I'm going to cut the hoses and remove the entire cooler with the fittings still attached so I can attack the lines standing up. I'm anticipating the worst however so I called the farmer down the street to see if he could help me if I strip them.

I don't need the car for the entire month so I am going to take my time.
