I think that It is about time for a new water pump, every time i turn the car off and come back there is about a half cup of coolant laying on the ground. I'm going to buy an edelbrock aluminum water pump, does that come with instructions?? I have never changed a water pump before, can anybody give me a rundown of what I have to do? Or would I have to take that to the mechanic? I would imagine you have to flush the system, remove the cooling fan to get to the pump, but then what?

Please help.

It is very easy... four bolts.

Make sure the mating surfaces are cleaned well (razor blade & alcohol works) and you get the gaskets to seal with some good quality silicone. I prefer Ultra-Copper.


The only trick at all is getting it to seal up and that's very easy.

 

You have an electric fan; that makes it much easier.

1. Drain radiator
2. Remove lower radiator hose from radiator - more coolant will come out, be prepared to catch it.
3. Remove belt
4. Remove any accessories (power steering pump, alternator bracket, etc.) in front of the pump
5. Remove pump - 4 bolts through ends of casting into block
6. With the pump on the ground, stick a screwdriver between a couple of the bolts to hold the pulley still, and loosen one of the others. Repeat until all 4 are off. Remove hose from pump.
7. Clean the mating surface of the block with a scraper or razor blade and some lacquer thinner, and clean the bolt threads with a wire brush
8. And now for my favorite Chilton's type of instruction — Installation is the reverse of removal!!
8. Put some sealer on the bolt threads; at least one of them always penetrates the water jacket, and can therefore leak

You might want to consider replacing the lower radiator hose while you're at it, because it's basically zero labor at this point, but a real pain when it bursts driving down the road.

since both the gasket surfaces are machined you shouldn't need much sealer to get a leak free seal. i like to use high tack so the gasket stays in place while i position the water pump. you stand more chance i believe of having a leak around 1 of the water pump bolts that go into a water jacket, i use liquid teflone pipe sealer on bolts like that. it's not a very hard job to change water pumps, pay attention and you should do fine.
