i have done this several times and its pretty straight forward.. make sure to line up the drive. i would also check the water pump now would be the time to change it. i also took a peice of vacc tubing about 6 feet long and ran it up under the finder and put a open end fuel filter on it. this will let the opti breath and not pull in water. don't know if it will help but from the looks of the inside of the opti i took off it can't hurt. robert

Replace the water pump and make sure you remove all the gasket material before putting on the new ones. Use a universal joint on the middle bolt on the drivers side.

Started pulling off my waterpump last night. Will a universal joint let me get to the last bolt without having to remove the pulley on the power steering pump?

Yes, it should. If I remember right, I used both a u-joint as well as a swivel.

I've found that you can get it off by just not using a deep well socket. I haven't yet needed a universal.

What sealer, if any, do you use between the water pump and gasket or betweeen the gasket and block? What kind is best? Glock94, how is your car recovering?

-Thanks

we got her running yesterday.. its so good to have her back. we used a sealent specifically used for coolant applications. we also replaced the thermostat. we think it froze up after drying out over a period of several days. the only real problems we had is we bent the screw on the pulley puller (ended up sawing it off) and we accidentally got the plug wires wrapped around the belt. all is good now :)
