Use some Permatex gasket seal on both sides of the gasket and on the bolts as they go into the water jacket.

Once you get the A/C and AIR brackets out of the way it should go pretty easily.

Let us know how it fits. I read a review of the Stewart pump on the forum and it said there were problems with the pulley fitting.

Have you install the Stewart pump yet? I want to order one if it fits and you had no problems installing it.

I have a Stewart Stage I pump. It actually is coming off tonight. It is about 2 years old, and has developed a leak. As of now I cannot tell if it is from the weep hole (I think not), or from the back (I think so).

I am replacing it with an Edlebrock Victor pump, due to arrive tomorrow.

I got a Stewart from my local speed shop and installed it last year.

It fit properly, bolted right and in serving well so far.

that was one of the most frustrating things i have done on the car so far! so much stuff had to come off it wasn't even funny!!!! there will be a hidden bolt under the AC compressor that is i think the bottom bolt on the passenger side of the pump! other than that.....good luck! :cheers:

Hope this is not to late. I just changed mine last week so I still have some fresh ideas for you.
1. Go to the "tech tips" section for help, print off the stuff you want for refference.
2. Pull off the passenger side wheel, this gets you in closer to where you are working.
3. Follow what is in tech tips.
4. Consider changing your timing chain - by the time you have your water pump off it's only a little more work to do the timing chain. That could save you having to do the whole job over again.

The hardest part to the whole jobs is ... it's not that hard. Don't let anyone tell you it's hard, just don't be in a hurry. I hope this helps. Let us know how you do. Good Luck. :cheers:
