Thanks for the post. I wasn't aware that the R4 compressors were problematic. Not much fun driving the car in $95-105* weather. I have just been sweating it out as I don't want to put a bunch of miles on my truck. The sanden upgrade sounds good. Trying to decided how much $$$ i want to put into it....
