Replying to: haguc (Jan 26, 2009 6:27 pm) 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.

Replying to: mike251 (Jan 26, 2009 11:39 am) 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.
#51 of 78 Adding Antifreeze to my car. by ranita05 Apr 03, 2009 (2:22 pm)
I have been trying to add antifreeze to my vehicle fruitlessly. I can't seem to get the little cap thing open. It looks like there's a screw on there. Help please!!??!!??
#52 of 78 Cap help by mike251 Apr 04, 2009 (5:08 am)
Is it your reservoir cap? If it is, mine came apart on me. The top part of the cap came off but there was still part of it stuck in the reservoir. Just take a flat blade screw driver and pry the piece out of there. Then stick the piece you pried off and stick it back in the cap. You can order a new one if you want to or you will probably have to pry it off each time you fill it. Replies to this message: intrigueguy37 (Oct 18, 2009 9:05 pm)

Replying to: mike251 (Apr 04, 2009 5:08 am) Hey Mike, I saw you help some other people in this forum with their overheating problems and was hoping you could possibly help me too. Well, I'm Andrew, owner of a 2000 Oldsmobile intrigue. Let me give you a quick background so you can have an idea of the situation. So at around 142k miles or so my car started overheating. I took it in the shop and they said I needed a coolant flush. It was quite obvious I did since there was lots of corrode inside the reservoir tank that somehow I didn't notice until it started overheating. So once I did that the overheating problem was pretty much gone. It would overheat when idle but some air bubbles that were left had eventually released out and problem was fixed. So a couple of months later it started overheating again. First guess was that since all the corrode had initially there, the leftover was causing the thermostat to stick. Strangely tho, eventually it stopped overheating. It would sporatically get hot from time to time but nothing ever that big. So one day I let my dad borrow it. Usually I'm only driving the car for rides that last less than 15 minutes. When my dad borrowed it he had to drive 45 minutes on it.        So on the way to work he noticed it starting to get alittle hot. On the way back is when this whole ordeal had offically STARTED. It got pretty hot but with my dad thinking that the thermostat was just sticking kept driving it...and driving it... and driving it until it went past critical and eventually shut off by itself. This is where he really messed up. He did this TWO more times! I couldn't believe it...but anyway he managed to get home although everytime it would shut off there would be no coolant left and he'd have to refill it.      So I take it in the shop figuring something small was wrong to find out they tell me I need to buy a new engine! They said the radiator was leaking, it probably needed new radiator hoses and either theres a cracked block or blown head gasket and that buying a new engine would be cheaper.      Luckly, I had my friend that was a mechanic and would do it alot cheaper. So first he replaced the radiator. And then bought the gasket kit and replaced all of those. It still overheated. So they replaced the thermostat. STILL overheated. Then even replaced the water pump, STILL overheated. They then even put this radiator sealer stuff in there thinking that there was a small leak somewhere that couldnt be seen. This still didn't help. So I took it somewhere else. A note worth mentioning is that after I put the sealer in and it kept overheating I drove it for a couple weeks just from school and back which is about 10-15 minutes, babying it the whole time. It only got to critical about 3 times over that span and I shut it off as soon as it did unlike my dad who kept driving it still. But so once I took it to another mechanic they said after taking off the radiator hoses that discovered that they were EMPTY. Apparently the people who put in the thermostat never primed it, so that meant there was no water in the block to get hot, meaning the thermostat could never kick in. After doing this it STILL overheated. So then they knocked the engine and after seeing no water shoot out from the above the spark plugs they said that the head gasket was probably fine although my water in my reservior tank had a slight shine to it. OH, also worth mentioning is that in that span that I drove it for a couple weeks I would only use water since it kept losing water everytime I drove it. Like I would drive it for only 5 minutes or so and when I'd check the reservoir tank it'd be dry. So I figured what's the use of wasting gallons and gallons of coolant. Also what I havn't said is that I'd only overheat after driving it for about 10 to 15 minutes and strangely sometimes it'd get to 3/4th's and then drop back down to 1/2 suddenly. This is what made me believe there was a air bubble somewhere. But then the place I went to even bled out the system and STILL overheated. Also what was strange is that when I'd drive it, sometimes the water wouldn't go dry and would maintain it's level.   But after all this, the last people I went to said that from process of elimination and after all that corrode in the beginning that there may be a clog in the block and that I should try flushing the radiator again and if that doesnt work i'll have to buy a new block. BUT then I talked to the first people who fixed it and they said that flushing it wouldn't help it since he had back flushed it with a water hose and that would have removed any clogs and that there must be a crack in the engine block. I disagree since when you use radiator flush its like a acid and should get alot more rust and stuff off then just normal water. Am i correct??   So in conclusion I'm hoping that flushing it might actually help or that maybe the 2nd place I went to didnt bleed the bubble out right since they didnt use the y adaptor procedure like I had seen on here but then someone told me the bubble would have escaped already anyway.   So can you or anyone else that reads this PLEASEEEEE, pleaseeee tell me what could be wrong with my car? Is the only possibility that I have a cracked block?? I've already spent a thousand fixing it and don't wanna have to spend another 1000-1500 on it (( Any advice would be MUCH appreciated. Thanks   Andrew
#55 of 78 Unique overheating issues by fasstln Oct 19, 2009 (5:56 am)
It sounds like you've repaced most everything related to the cooling system except the engine. You could try spraying a water hose into the engine system (do it from both the entry and exit ports just to ensure there isn't some kind of blockage. Also, did you replace the water pump with a GM piece or some other aftermarket piece? I've heard that some aftermarket pieces don't do a good job at spinning the water pump propller, or that the propeller is too small, thus the coolant isn't circulated quickly enough.   If you're loosing coolant, then you have a leak somewhere. If you don't have coolant dripping from under your car, then I would guess you must be losing it in the engine.   Also, if the car is overheating, you shouldn't drive it until the computer shuts it down. Turn it off much sooner than that. Also, you should probably change your oil if you let the engine run that hot (very high heat kills your oil). You could use that time to inspect your oil to see if you have any coolant leaking in there. Replies to this message: intrigueguy37 (Oct 19, 2009 7:54 pm)
#56 of 78 coolant problem by mike251 Oct 19, 2009 (6:41 am)
wow. That is amazing you went through way more crap than I did. I agree with the first guy if you have coolant leaking into your engine then it will show in the pistons or your oil should be getting full. Remember that this system takes pressure in its system at all times to keep the engine cool. Maybe your holding tank needs to replaced. It is also possible they did not bleed the system like I wrote down. You have to do it just as what is put in my notes otherwise it probably will not work right. The other thing is you can not get the pump or thermostat from autozone they will not work right. There is no bleeding port on the engine so it is very important to bleed the engine correctly. not true with bubble escaping. it will stay in there because air will stay at the highest point which the engine block is pretty much the highest point.

Replying to: fasstln (Oct 19, 2009 5:56 am) The guy that originally fixed it said he back flushed it with 15 pounds of pressure with the water hose, is that the same thing as what you said? "You could try spraying a water hose into the engine system (do it from both the entry and exit ports just to ensure there isn't some kind of blockage."   The water pump was a OEM remanufactured water pump from O'Reily's. Their products always seems to be pretty good so I don't think that could be it. And well the strange thing is, is that i pulled the dipstick out and checked the oil and it looked fine, no milky look to it at all. But what should the oil look like and what would it look like if the high heat messed it up?

Replying to: mike251 (Oct 19, 2009 6:41 am) The holding tank? I've never heard of that term, what exactly is that?   And hmmm I was thinking the same about the bleed procedure. I never saw them use the y-adaptor and all that so i'm gonna bring them the procedure on thursday and see it helps. Man I'm trying everything possible to not have to replace that damn block lol I appreciate the help though. You sure about the bubble escaping tho? Cause I've had two or three mechanics said any bubble would of escaped by now, maybe they were saying that based on other model of cars and the intrigue is just especially different so it cant just escape out?
