So friday night i'm out at a meet at the 8ball cafe on the a12, on the way back i'm pushing on coming off the slip road and i look down to notice my temp gauge dropping. I backed off obviously and it continued to fall. i pulled over a little later and tried to find the problem no leak, obvious. called a mate who's a master tech at vw and he advised likely scenarios, Water pump or head gasket I have recently replaced the stat and the temp switch due to it running a lower temp than normal previously. since it has been fine however. so i text my boss and asked for monday off to solve the problem, he kindly agreed and i waited until traffic subsided and went off to Euro Car Parts. They promptly supplied the parts according to my registration: Water pump inc housing Water pump belt New stat (just in case) Stat o ring Two big bottles of G12 off i went home and set about removing the front bumper using an online guide, a quite bizarre way to remove a bumper if you ask me! i ended up accidently pulling the mount off on the drivers side which i will have to fix back more securely in the future. Then the arduous task of removing the "front clip", now i've read many guides and references to this taking about half hour to an hour, rubbish it takes much longer unless your car is brand new! look at that wasted perfectly good coolant from a month ago ended up having to leave the rad hoses attached as they just wouldn't let go! we then proceeded to remove the fan etc and were faced with this where the hell is the water pump and why does it look nothing like any of the guides back in and on the lap top we have a problem i have a water pump from ecp that looks like this: which clearly isn't what i need. spoke to audi and they confirmed i had the wrong part, ecp were insistant it was the correct part for a AWT 2001 1.8t i needed this: which meant some of this... yes thats the timing belt, not looking forward to the removal and replacement of that! Audi needed the original pump for exchange £33 which was reasonable so we carried on to remove it. got it out, nothing wrong with it at all, completely intact, tested the spindle etc absolutely fine! rang my mate at vw back he said what did the stat look like? i said we hadn't looked so while on the phone i popped it out gutted! took the whole front clip off and the cambelt for the sake of a half hour job!!!! managed to get the belt back on and timed correctly, starting the car up was easily the scariest moment ever! all fine and running sweet. took a while to bleed the air out of the system and i took to blowing the water through the top hose to get the air out, this resulted in an interesting look... the car is now running up to temp just fine and all is well. i was thoroughly knackered after a whole day in the garage! ended up with one metal clip spare which was good going considering how many we had to remove lol.
