#39 of 116 Replaced the water pump and gasket this weekend on my 3.5L

This ended up not being too bad of a job.
Drain the reservoir coolant and then remove the reservoir by (a) unscrewing the two bolts at the top of the shock mount, (b) disconnecting the hose near the thermostat, and (c) disconnecting the electrical sensor under the reservoir.
Now put a half-inch ratchet on the tensioner pulley and crank that bad boy over to release tension on the accessory belt (easiest to remove the belt from the top pulley). Be sure to note how the belt runs across the pulleys. Took me 45 minutes to put this back on because I couldn't remember the order it was in (should have taken a picture!).
You'll need to loosen the idler pulley and pull it out as far as you can (the bolt on mine was too long to completely remove it, but I only needed to get it out of the way) which will provide you enough space to remove some of the bolts on the water pump.
It is also easiest if you remove the 4 screws holding the water pump pulley on, which will also give you access to bolts for the water pump.
Now you just have to start taking the bolts off the water pump. There are a lot and you need to keep track in which holes the long bolts go and which ones have the shorter bolts.
Once you remove all of the bolts and pull the water pump off, you'll need to clean the engine block of any stuck-on gasket from the old water pump. A razor blade is best, but a flat head screwdriver would suffice.
Also, take a can of compressed air (like what you use to clean a computer keyboard) and blow out each of the bolt holes in case any gunk/debris fell in there upon removing the water pump.
The instructions said to put a little bit of gasket sealant on the new water pump gasket, so I used some RTV sealant for high-temperatures. It's probably meant for exhaust applications, but 200 degrees is pretty hot too.
I put some of the sealant on the new water pump, laid the new gasket on top, then put additional sealant on the new gasket (so the gasket now has sealant on both sides).
I put the new water pump and gasket on and then started threading all of the bolts.
Put the accessory belt back on, though now might be a good time to replace yours if necessary, and reinstall the coolant reservoir.
Go ahead and add some distilled water and Dex-Cool coolant to the reservoir and start the car with the cap OFF of the reservoir. Let the car get up to temperature and add more water/coolant as necessary. This should allow the system to burp out any air.
Finally, put the cap back on the reservoir and take it for a drive. Please note any low coolant lights on the instrument cluster or overheating. Since this is a closed system, it is probably important that the reservoir not be overfilled.

I have a 2000 olds intrigue with about 50000 miles on it.The thermostat gauge has been reading in the red, or very close to it, very frequently, although the coolant level is ok & the engine doesn't smell "hot". The gauge going up seems to be associated with a banging sound, which can also be felt, on the driver's side. The GM mechanic replaced the thermostat & bled the system, feeling that an air lock was causing the banging- the symptoms reappeared within 12 miles after leaving the garage. I haven't noticed that the performance of the car has been affected- that is, I still get 25-26 mpg. What is wrong?

So... my car recently started to leak a little bit of water after it was turned off each night. I am pretty sure it is the water pump because it has 135k on it and hasn'te been changed and seems to be coming from that general area. I am going to look into it closer. Additionally, this winter when it has been very cold (less that 15 degrees) the temperature on the car has been getting too hot. After reading the posts in this thread I believe it is because it is the original thermostat with poor design and when I do rev the motor it cools back down as described by other posters. So.. I am looking to get the parts to do it myself, but saw some posters were pretty picky about where to get the parts from.
I see the part numbers listed by others for the gmpartsdirect site for the water pump. I needed to get a water pump and the thermostat for my 01 with the 3.5, however, gmpartsdirect doesn't have the thermostat, they only have the water pump. rockauto has both of the parts, any suggestions on which one I should get as they have three different brands of thermostat (none listed as oem) and 7 water pumps (bosch listed as oem). It looks like the cheaper water pumps may just not come with the pulley, but that would come off the old pump anyway correct? Is the OEM truly the same as what I would get from the dealer or gmpartsdirect? Just want to make sure that the parts I get are going to work for me.

I'm wondering if your car is not signaling the fans to come on when the tempeature comes on. Have your mechanic check this.

Any of the aftermarket thermostats for the Intrigue should work fine. I believe they should be 180 degree. I haven't had to replace the water pump but all should have a warranty. I wouldn't buy the cheapest nor the most expensive. go for one of the pumps in the middle.

sorry there is only one thermostat you can buy and none of the after markets will do. Obviously you have not change one on this engine. The oem is the only way to go for this part. It is only 34 dollars through the dealership. Make sure you read the earlier posts for this coolant system. It is not the typical gm coolant system.

You have an air problem. Since you have a popping noise when the temp goes up. It needs to be fixed before you crack the head. If you use the manual shift 1 2 3 does the temp stay down. If you keep the rpms up by using the manual shift and the engine stays cooler then your pump might be bad or your system is not tight. See earlier post for more information about how to fix this that I have already wrote.

Actually mike251, I changed the thermostat MYSELF this fall. I can go into a long dissertation about the difficulty of opening radiator drain valve (simple lift and turn, no tools necessary after all) and block drain (never was able to get it open) but I don't want to bore anyone. i purchased my thermostat from Advance Auto Parts. I believe the brand was Stant (had to go online to check it). I don't know if that is the OEM brand or not. GM changed the design of the thermostat before the 2000 model year. My 2000 Intrigue had the re-design one on it and was built in early fall of 1999.

Well I guess your engine is built different then most of the 2000 intrigues. Thanks for not boring anybody.

Glad to see everyone agreeing
So... Mike... would you say that I should not get any of them that are offered by Rockauto.com? I am not sure which brand was used factory, but the pictures of all three of them (thermostats) look identical and would assume that the thermostats would be teh same. (hoses included as well as solid case/thermostat piece). I love saving money when I can, but at the same time I dont' want to get a part that is going to not work properly either. Thanks in advance for the help.
