My A/C recently crapped out! I live in Houston so this is a big problem. I was on a long commute when it happened. When I went to turn on the A/C at highway speed the engine RPM dipped violently and then the econ light came on. I assumed the compressor locked up. The car runs fine besides no A/C. Upon inspecting the compressor, I noticed a black tacky substance coming out from the front of the flywheel for the compressor. Does this sounds like a crapped out compressor??
I also notices a coolant leak behind the engine block above the transmission. Is this a common place to have a coolant leak? What steps should I take to diagnose and repair?

One last question: Would a DIY timing belt change be a doable task with a Bentley manual and a day dedicated to the job? I found a great timing belt kit on ECS Tuning and really would rather pay $250 and DIY instead of $1400 at the dealership!

the coolant leak may be a rear coolant flange going out: http://www.audizine.com/forum/showthread.php?t=189137

i havent had to do it, but apparently its a real PITA to get out, working blind. how is the coolant level in your reservoir? make sure to keep it full, use distilled water if you have to.

I am also in Houston area and have a spare A/C compressor if you need it.

Thanks for the info and great link. I have been keeping the reservoir full but it usually will empty in about 3 days. I have been using regular tap water and g12 radiator fluid to fill it up. Should I change the coolant after the repair? If so, how??

you should drain the coolant and flush after the repair:
