Re: How do i change the water pump...
- Remove the coolant overflow bottle.
- Remove the battery.
- Loosen the pulley bolts.
- Loosen or remove the drive belt.
- Remove pulley bolts
- Remove all studs and bolts from old water pump.
- Pull old pump off. Use a screwdriver to start it but be careful not to bend the old pump. Also, tapping the center of the pulley lightly with a hammer may help loosen it. If it is hard to get out, check and make sure all bolts are removed. When you remove the pump, there will not be enough room to remove the pulley drum from the pump. This is important to remember when installing the new water pump.
- Scrape area off with a gasket scraper and razor blade to remove old gasket. Make sure its clean! Spray it with brake cleaner and wipe clean afterward.
- Spray both sides of the new gasket with high tack. High tack works much better than the goop because it is clean, even, and seals well.
- Slip gasket in carefully and be sure it fits properly over bolts and is in correct placement against block. Press down to ensure seal.
- Spray the inside of the water pump with high tack evenly.
- Install water pump into correct place against block making sure that pulley drum is already hanging from new pump or you will not get it on afterward!
- Install bolts and studs and tighten down.
- Install pulley screws and tighten as best you can.
- Reinstall and tighten drive belt.
- Finish tightening pulley bolts.
- Reinstall battery and coolant overflow bottle being sure that bottle is empty.
- Let sealant dry overnight.
^if you follow the book and have little experience that is the best way
I have 11 years experience working on cars and 4 years were at a cadillac dealer
This will give you more hand room I Take the 2 nuts off the bottom of the front motor mount and back motor mount, on the passenger side then I jack up the motor on the passenger side end of the oil pan with a board between the jack and the oil pan. You can jack it up a couple of inches, it gives you plenty of room. I leave it jacked up until I'm done, even putting the belt on is alot easier. Then lower the motor, and put the nuts back on the mounts
