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.

Do they look like the one you are taking off? I got one from autozone and it was nothing like the one I took off. It was a standard gm thermostat. The one I took off was part of the aluminum casting and was like 3 to 4 inches long. If it looks the same maybe, but I wouldn't do it. Just look at the car forums and the problems people have had with this coolant system. Is it really worth the headache it could cause. The other thing you could do is call gm dealer and get the P/N and see if it crosses over to the ones you are looking at.

The original owner purchased it in October 1999 which means it was built earlier that late summer/fall. Not unless there was a special 3.5 L engine, I think it is the same. If you know differently, please share. I'm always looking to learn.
 
Looking at Rockauto.com, all 3 of the thermostats are the same. I used the one from Stant. It's hard to see the ACDelco (which is the OEM) since it is more a sketching than a picture and it's at a different angle. Since mike251 and i are disagreeing, you can always call Rock Auto and ask them. I know of others from a different forum who have contacted Rock Auto about parts and have received excellent service. If it makes you feel more comfortable, you can purchase it from a GM dealer.
 
Good luck. If you need any other help with this project, please post.
