Sorry to say that the water pump on my stock '87 GT V6, 69,000 mi. has begun to drip. Sometimes not at all, sometimes a little, sometimes a lot. Been under the car, wiped everything off, and searched fior the leak .I believe it is the weep hole on the pump. Tomorrow I plan to change the pump. I know this has been covered on the Forum. I have searched, but not found a step by step. Anyone have any "helpful hints" on how to get the job done.

Posted a CAT and O2 sensor question a few days ago. Got several helpful responses. Changed both and the car runs absolutely great. The down side, as soon as I got done with the CAT I got a water leak.

Thanks All !!

I changed the WP on my '86 GT a few months ago. A few tips...

- Remove the battery to make a little more room.
- Loosen bolts on WP pulley before removing the belt.
- If you can do it, remove the old pump on Day #1 and install the new pump on Day #2 - much easier on the back!
- my pump used standard (metric) hex head bolts, not Torx, so bolt removal and install was no problem. You may not be so lucky.
- Get a pump with a steel impeller. Advance sells them for cheap.
- Keep track of where the bolts came from. If I recall, all the small ones are the same but the big ones are different lengths.
- Some bolts enter the water jacket. Make sure to use sealer on the threads.
- Do a search and read other posts on this topic. There are some good ones with pictures.

I did 99% of the work from the top. Other than cleaning the old gasket surface, which took hours, this job was fairly straightforward.

The two larger long bolts on each side are the ones that go into the water jack, like said, be sure and put sealer on them.

Watch you don't overtighten the top middle bolt that has no metal behind it. You will break the water pump if over tightened.

If your having trouble from above, remove the wheel and the splash shield in the wheel well and you can do some of the work from below a lot easier.
