I had a coolant leak that started last week so i checked the Aux coolant pump and it had some grunge on it so i replaced it and the hoses.
tonight after driving with my AC on the leak came back but ITS NOT the aux pump

i'm REALLY hoping its not my water pump as this is the 3rd time i have had the car in service mode this summer! if its the water pump i'm not driving it anymore this year and will pull the motor and stage3 the POS.

So did some testing tonight

here is a video with no AC on and the car just idling (i removed the coolant tank cap to let the vacuum out and it caused the coolant to drip in the video)

you can see that coolant is dripping at the end of the video


and here is another video but WITH AC running.. its a lot noisier but i think due to the stern motor mounts maybe??

fixed it.. LONG story!

Chris's S4

time to read.. lol

What happened?

OK so

over the winter i actually dont' drive my s4 (allroad is for that)

so my AC system was going wonky on me so i replaced my AC compressor

well somehow the back bolt on it fell out!!!

so the AC compressor was off kilter and sitting at a slight angle even
when i turned the AC on it would vibrate like crazy
which caused my ACC belt to go off and wear away/snap(on my second one now)
then in turn caused it to vibrate against the one coolant line from the hardline down to the oil cooler!

the hose had a decent sized tear/wear spot in it!


oh well easy to fix at at least my water pump is actually working hahaha (considering it only has 25000km on it)

i actually have all 3 AC compressor bolts on

but the body(ac comp shell) seems loose!?? wtf? that would explain the crazy vibrations i feel

also is the compressor wheel supposed to turn wobbly?

then see what i'm talking about with the movement.. i'm not sure.. i may remove the compressor and see what is up with the shell part
