Now in my other post about the rattling noises..a local mechanic (from listening to it) tellls me that he thinks the water pump is going...and we open the radiator cap and the water is just sitting there while the car is running.just barely flowing...and this was after i drove about 10 miles to his place and left the car running..he listened to it and then popped the radiator cap..all while it was still running..and the water looks like it is at a stand still..........now why is my temperature guage not running hot..and can i change the water pump without messing with the timing...or would it be best to get the chain replaced while i am at it..thanks

Replacing the water pump does not require messing with the engine front cover, so you won't have access to the timing chain anyway.
Steps for replacing the water pump (from memory):
1. Disconnect negative battery terminal
2. Support engine from below with a jackstand
3. Remove belt, alternator, coil pack
4. Remove engine front (passenger side) mount
5. Remove water pump pulley (* see below)
6. Remove water pump
7. Install new water pump using a new gasket
8. Install pulley, engine mount, coil pack, alternator, belt
9. Reconnect negative battery terminal
* The 4 pulley bolts are hard to open/close, because the entire pulley tends to turn instead of just the bolt. The best way is open one of the water pump bolts (the top one that'* just behind the pulley) with an open-end wrench until it holds the pulley in place, and stops it from rotating freely. Then opening the 4 pulley bolts is no problem at all.
Hope this helps

Hello willwren
I'm doing just fine, my car even better. The new engine I put in it is great, with only 40K on it, has great power and runs real smooth. I've done lots of other stuff on the car - heater core, radiator, shocks (front & rear), brakes.... and the list goes on the moment I'm satisfied with the way it drives I'll start worrying about looks it needs some bodywork and may even get a full repaint.
I'll also be taking apart my old 3800, and I expect it to be lots of fun - especially knowing that I won't have to ever put it back together
