there is a knocking noise coming from the water pump pulley..i think, the pulley also wiggles when its running. If that's what is wrong, how long do i have to fix it and is it hard and expensive to fix?
No it isn't hard to fix, first loosen the little bolts on the water pump pulley, then take the belt off, then unbolt the water pump and take pulley off old pump, clean off old seal from block, put on new seal, you may have to use gasket maker or silicone, install new pump, and bolt pulley on to new pump, then reinstall belt. Oh I forgot you will have to drain the antifreeze before you start, and refill it after you are done! Start the car and let it warm up and look for leaks, if you see a leak you didn't get it sealed properly and will have to repeat the sealing process and antifreeze. Takes an hour or so to do!
