will you just change the elbows already lol they leak, so fix them. end of story. its 12 bucks and a hour of your time tops.

your fans dont turn on till 212 deg's, and turn off when the car is off. to test if they do work turn the a/c on, if the a/c blows cold the fans will come on.

if they dont come on and the a/c sorta works, aka compressor is turning then unplug the temp sensor, if they turn on the temp sensor is bad.
