Now what can go wrong?

I forgot to add the bit about buying new bolts. The other guys have me covered here though. Definitely get the new bolt kit from MSA. It costs, what, 5 bucks?

Do have a question for you all. I ordered the pump and bolts and its on its way. Upon installation is an RTV required on the pump. I haven't yet looked at the FSM or other books about the car but I'm wondering what you guys have done. From what it looks like my pump has a crap ton of red RTV holding it on the block. Not sure if there is even a gasket there. Advise is appreciated.

Yea, there is a gasket. I used a thin layer of RTV on both sides of mine and no leaks so far.

I personally prefer a thin film of silicon on the gasket, both sides. Too much and I dont think you get even pressure on the gasket when torquing. No RTV and the inconsistencies of the metal (warp, pits) may lead to small leaks.

I had to chime in...I have pretty much done all of that with my Z over the last 25 years. One thing everyone should check/change when doing a water pump replacement are the little Belt Tensioner Bearings. They are around $10 ea and will quiet your engine alot! They are the source of many 'mystery' noises.

If you're talking about idler pulley bearings, you'd only need to check/change them if your car had them. Those would only be on the ones that have AC.

sblake01 I took my A/C belt off months ago as I don't use it at all. It was most definitely the water pump as I took it off and found the bearing burned. (I disassembled the pump...had some free time). There was also a stream of coolant coming from the weep hole on the old pump. Had a nice adventure putting the new one in.
