STOP what you are doing before you damage something!! Whatever you are trying to remove is not the water pump. Neither the sparkplugs nor the "timing belt" cover needs to come off. Remove the fan belt. Remove the fan (the nut is LH thread- means it turns left to tighten and right to loosen). You will need a large wrench (32mm) availible at sears.The water pump is directly behind the fan and is held in by 4 10mm bolts.

Basically its said,that when water pump is replaced,its also advisable to replace timing chain.The timing chain is either worn out or while replacing water pump,the timing chain got misaligned.It has to be inspected.Most probably,it needs to be replaced.

Serpentine belt broke. A serpentine belt drive runs everything: power steering, ac, alternator (electrical power), and the water pump (explains the overheating). I'd bet anything that your belt broke.

BS. Water pump should be replaced with the TIMING BELT. The serpentine belt doesnt even touch the water pump. If you have a V6 that is. but you didnt say what engine you have.

Hey Andy a quick was to solve your problem is to locate a similar vehicle in a car yard, go have a look at the configuration and draw your self a quick diagram whilst your there.
