Oldsmobile Intrigue - Recent Questions, Troubleshooting & Support

Question edited for clarity and typos. Question moved to model category. You just need to identify the part and replace it. Check the diagram on the top left. If it is part 7 it is discontinued, so you would have to remove it and have it MIG welded. https://www.gmpartsclub.com/v-2002-oldsmobile-intrigue--gls--3-5l-v6-gas/cooling-system--radiator-and-components https://www.google.com/search?q=2000+oldsmobile+intrigue+coolant+parts+diagram ..

You probably have a bad resistor. I'm not sure on your vehicle but it may be located on top of the housing that your blower is in. Hope thats of some help to you.

remove gas tank

On the valve body behind the vave body cover on the side of the transmission. The cover could be in one of several places depending on which transmission is used in your vehicle. With GM, sometimes it is impossible to remove the cover without pulling the transmission.

its on the top of the motor in the front by the cam shafts.

1999 oldmobile intrigue over heating. Heat not blowing hot

Should be next to the batterya black box

Follow the main hoses that run from the radiator to the engine. There will probably be a upper and lower. One may have blown off or ruptured. Lots of light will be necessary. Alternately, to try and get a better idea of where it is leaking have someone with old clothes and saftery glasses watch the engine bay when the car is running. Make sure all clamps are tight on the hoses as well.

Depending on what engine you have, the 3.8 has a plastic elbow coming out of the lower intake manifold that goes to the belt tensioner assembly, which has 2 hoses coming out of it for the heater hoses. That elbow likes to crack. The older 3.8 has a nipple there which also likes to crack that runs to the heater core. Either way that's where i'd be checking first.

You fill at the coolant or surge tank,and the drain plug should be on the side with the lower radiator hose or the passenger side,it will look like a thumb screw or wing design urn counterclockwise and pull out at the same time.

Should not be too tough to change. The front sensor is between the engine exhaust manifold and the catalytic converter.

The red plastic cover should just pop off, then you will see the head of the terminal bolt. you'll need to remove the braket holding the battery in place, just remember to replace it to hold the new battery still.

under the thermostat housing. there should be x wire coming from the left to it. its hard to see with the hose on

when changing the thermastat was there oil there also? Sounds like you have a blown head gasket, sorry

Possibilities:

Low coolant - check and refill if necessary
Thermostat is stuck shut - replace
Radiator clogged - clean fins of radiator. Have the radiator flushed.

Use channel locks to pinch the fastner then pull the hose off if it doesn't move push the clamp off the hose if still doesn't move then try using the wrench to twist it back and forth then it should come off. Then put new one on and refasten the clamp. U may have tolubeit to get into may want to switch the clamp to new ones

just drain it, its pointless to flush it. there should be a drain plug on the bottom drivers side of the rad

There is a plug in the bottom inner side, facing the engine, on the drivers side. Hope this helps, TJ

it takes a little special socket, u can buy them at any parts store.

Use a strong magnet and spin it back to where it should be. I saw 4 videos that said it worked they went from hot to cold though. I got mine half way around so far going to get a stronger magnet
