Question about 1998 Pontiac Grand Am
First you have to take off the exhaust manifold. then take off the top motor mount and lift plate on the passenger side on top. then take off the 25 little bolts and nuts off the timing chain cover. with the cover off, take out the bolts on the timing chain tensioner (towards botton, by the crank, looks like a little rod in a aluminum housing). now take off the curved tensioner shoe and the chain will loosen. take the chain off. now the fun part is getting the bolts off the back of the water pump to the block. then the bolts connecting the water pump to the steel housing. and finally the three nuts connecting the pump to the chain housing. not hard just frustrating. replace the pump and new gaskets (comes with pump) and bolt back everthing back together. you may want to change your thermostat while your there since its right by the pump. now putting the timing chain back on and having it in time isnt the hardest thing but if your a first timer take your time. go to a mechanic and ask to print out intalation insructions on timing chain installation. then bolt it all back together.

Is this a 1998 pontiac SE? Because I just had mine fixed and have all the instructions right in front of me...the mechanic I went to was amazing and charged me half of what I was quoted at Midas, and even gave me the instructions on what he did so that I could show (husband/father/uncle) what was done. The water pump on the 98 is the worst thing to replace because they had to take off the exhaust manifold and timing chain...the bolts on the exhaust manifold were frozen...but what can you expect on a car with 200,000 miles and is 12 years old? If you are looking for detailed instructions and are still checking this forum, I can copy and mail you what I have.
