I have come to find out that you ABSOLUTELY CANNOT USE AFTER MARKET PARTS ON AN OLDSMOBILE INTRIGUE GLS MODEL 3.5l V^ with a north-star Cadillac engine in it ........USE DEALER PARTS ONLY!........Why?.......This Video will explain.
Pretty good video, I just bought a 2000 Intrigue with 88K on it. The reason they sold it was, it was running hot. I changed the water pump, thermostat and flushed the coolant. Still it ran hot when I drove it, when it was idling it, it dropped in temp, only when I ran it above 2K it started to climb. Checked the fans and they came on at the right temp. I was getting frustrated that I couldn't figure it out. Ran it through several heat cycles and made sure all the air was out of it. Then I thought about checking the radiator, mainly because it stayed cool when idling and only when it was being driven it got hot, which normally it should be the other way around, the more air, the cooler it should be. Anyway, I pulled out the old inspection camera and put it down between the AC condenser and Radiator and found the reason is was running hot under a load. The radiator was being blocked by debris. Normally, if you look straight down the radiator to inspect it, it may not look clogged, but when you run a light behind it you will see the radiator fins filled with dirt. Anyway, I flushed it out with water and then road tested it and that was what was happening, ran cool after doing an external flush. The way the Intrigue gets the air is from the front of the car, no pass though grille, so it picks up a ton of dirt, leaves, dust, grass, paper, etc.
Your advice and information is spot on, but i would suggest getting rid of the dexcool crap. It's terrible and really hard on the engine in the long run
Matt, when my water pump went out. I had the dealership do the service. No problems. I do know my temperature gauge will almost go to half way when I am sitting in traffic. But it does not overheat. I also get regular coolant flushes. This engine runs great for me. My mother bought this car brand new. It was well maintained. I like this car. Great video!
My son is having just the opposite problem with his 99 olds intrigue gls. When sitting and idling it runs fine. Even runs ok with it sitting at idle up to 2k rpm sitting in the garage. It's when he's driving it, it gets hot. GRRR. I'm getting so tired of spending countless hours on trying to diagnose issues with these newer vehicles. I'll take an older vehicle over this new garbage any day. And now I see that the parts are no longer available? Thanks for the video. I think I'm just going to pull his thermostat and let it flow freely or try to find something that's aftermarket.
Clean the fins of the radiator and A/C condenser and take off that stupid cover on top of the engine and watch the temp go down. Why they took out the front grill I will never understand. Not enough air goes into the front of the engine to cool it down. The air coming in from under the front makes it a giant vacuum cleaner, sucking up tons of stuff while driving. I am planning to remove the cowling in front of the radiator and add some more window screen to keep the junk out of the radiator. The 3.5 engines are garbage, hastily made and not thought out before throwing them in as a replacement for the 3.8. The 3.8 is still one of the best engines built by GM.
OMG. Just picked up my 2000 Oldsmobile intrique , 90 000 km, from the repair shop: Had some tiny leaks. Miniscule leaks, but my husband is so fussy.) The pressure test suggested new water pump. After installation it overheated. Never overheated before. Could not bleed it fully. Installed new thermostat. Still overheats. Suggesting head gasket. But can not get one. Was told "car is too old!"?
This all makes sense now. I had to bring the rpms up for it to cool down. Im having issues with the coolant light staying lite. Every time i check the fluids, it has not moved. The car has started to do a "putput" feeling, so i stopped driving it. Did you make a video after? How do i get a discontinued part?
Hey Matthew, thanks for the information. How can i get the location of the coolant temp sensor for the 2000 Oldsmobile intrigue 3.5l v6 Cadillac. You didn't show the location in this video.
I have given up on my 4.0 aurora {for now) it's a 'rescue'.. If I jump on it at ANY speed, it will immediately start to overheat but it seems like it actually blows it's coolant out. I see they run an exhaust tube into the rear of the crossover manifold right behind what seems to be an egr on driver side. there's a small gasket in there that was leaking coolant exteriorly when I bought the car, which I replaced. A LOT of work to change such a small and cheap gasket. My question is are they using that area to cool the exhaust gases before introducing them to the engine? There seems to be no obvious symptoms of head gasket issues. I have searched egr cooling and the only info that keeps coming up is for Duramax engines.
Hi Matt! Thank you so much for the video! I went to the GM dealer and he said the parts are no longer available. Would you happen to know what part #’s you put in? Thanks again! Gerry
I have 2002 Intrigue, 3.5L engine. Perhaps AC Delco thermostat is specially designed for this 3.5L Shortstar engine. I couldn't find it. last year i bought MOTORAD 464180 {#19137284, 56480} OE Standard; 180F thermostat for this engine (I am not very sure if this thermostat is really good for 3.5L engine. perhaps good for 3.8L one which is Northstar engine.). I was not driving my car long time, because I replaced head gaskets, Power steering pressure hose new front and rear brake pads, new discs, new ball joints, new front struts, new water pump, new belt, new crankshaft sensor (AC Delco) Note: I bought Dorman brand but it didn't work, when I replaced AC Delco instanly worked, new control arms, new tie rod ends, new water tank. I did all these jobs myself. I sterted to drive it on 17 Oct 2019. Cooling system was showing as normal just under of middle mark/ white line in instr panel. After few km driving, it started to be stupid. Water tank has bubbles, plus throwing out coolant water when I park somwhere, plus yesterday it show very hot level hit red mark after only 30 min driving. My car was not running proper speed it reduced speed even I accelerate it. when i looked at instr panel, I noticed that water temperature hit at very hot red mark. Instantly I stopped somewhere on the road and I shutdown my engine. I waited about 30 min it get cool. I add new distilled water (I had inside car), then I qickly went to my home. I was lucky it happened near my home. Regarding water pump it is not AC Delco but brand new. I don't think so problem is water pump. In my view they sold to me 3.8L or 4.0L engine thermostat instead 3.5L. I scare to drive far distance, such as on Hwy. Now, what to do? How about radiator? It is original one. Do you think it is clugged inside thin holes with calcium and water not passing good enough? Or something else? i am second owner. When I removed thermostat housing, I saw a small and short size thermostat. I am still keeping it at home. Perhaps, someone first owner or some mechanic replaced this small size thermostat before. My purchase of thermostat is Motorad brand and Made in Germany MOTORAD 464180 {#19137284, 56480} OE Standard; 180F . I paid $45 CAD plus tax. from Part Source store, a side company of Canadian Tire. Note: My heater works good. I always feel good hot air. So, no problem with heater. There is no signs of a head gasket leak or anything. It blows no smoke, there is no water splurting out and there and no signs of water in the oil. The motor shows no signs of over heating. No white smoke out from muffler.
I have a 2002 Olds Intrigue, had the water pump replaced 4 months ago with AC Delco aftermarket pump, having the same exact issues as in your video, problem is my mechanic said that a GM water pump is no longer available for this vehicle, any other options
Sounds like the same symptoms as a coolant crossover pipe. Only missing the leaking coolant on drivers side from gaskets that need replacing but same sort of symptoms
Is the 2004 alero the same engine. I’ve noticed the same thing I sit idle I overheat n when I give in gas n start going I cool off. I just went n replaced both hoses cuz they looked like they were leaking. Well I was having problem with overheating the car is used so I’m not sure if the water pump has previously been replaced but it definitely is making a noise it’s coming from the water pump n leaking underneath that spot on the ground I can’t actually see the leak but it’s coming out pretty good. So before I go buy my pump from oreillys my buddy works there do u think maybe I should look into this Cadillac engine first since I’m having the idling problem.? I thought that was odd myself sitting n overheating vs driving n going to normal.
I had the opposite for myself, when I'm on the eway and have it around 100 mph at 3000 rpms it will sometimes bring the temp up just before it overheats. It has overheated 2, this is after about an hour of it being at 3000 rpms at 100mph. I have to bring it down to 2500 rpm and it usually keeps me from overheating. It has a new water pump, radiator, and thermostat. Can anyone offer some type of reason it's causing that please. Any info will be appreciated, btw I bought the car with 87,000 miles because it was in a fender bender my neighbor gave me a great price. I bought the headlight, pulled the fender out a little and drive it as is. Same model gls. It is a good car and it is sharp just without the spoiler in the back. I've done a few other things to the suspension and front end with rack and power steering pump. I have invested a decent amount of cash into and don't want to blow the gaskets or anything so if some can please give me any advice I would really appreciate it.
I have 1998 oldsmobile intrgue doing the same thing 3.8 liter V6 it has 3800 series 2 engine other than that it runs.only problem i got my battery when dead a couples years back my gas gauge flip on back side of peg thing i have read that is common thing for gas gauge do that if the battery is low and you go try start gauges will go all crazy and move on you.but after i put a new battery my gauges work fine just gas gauge didn't come down cause here i got i know it not broken cause when get low on gas the light come and ding until i put enough gas in it to turn light off
i have a intrigue and mine over heats and my ac doesnt work and my fan wont kick on to keep the condinsser cool so i have no ac right now i bought it for $300 and i havent had to do anything to the motor it has bout 170000 miles and hasved owned itfor 4 years it has the 3.5 twin cam motor in it is that why i cant figure out my ac cause it being the caddy motor
Thats actually common with alot of GM vehicles with the temp gauge to go slight above the half way point and the dealerships will even tell people that its within normal parameters and many I have seen will go a notch above half and stay there and thats even while driving with air rushing up to help cool the engine. GM fine quality for Ya, and Im being sarcastic! GM a step below the rest.
I have a 01 olds intrigue same problem I got the water pump from gm but they discontinued the thermostat housing and thermostat it runs a little hot but when I give it gas up to 2500 rpms it goes back down to normal temp then I notice that it has air pockets in it the house by back of motor that runs to heater core pops with pressure I cant figure it out at all
No. The engines in alero are 2.2 ecotec, 2.4, and 3400sfi. In all 3 engines the thermostat is on the driver side of the engine directly below the throttle body.
I have a 2000 intrigue w the 3.5 twin cam .is thisCaddy engine as well. ? I think it's a gx model. Also can youttell me where yougot the parts ? And do you have video for bleeding the coolant ?
Hi Matthew,I have same issue overheating 🥵 it’s a 2000 intrigue same model as the one on video and in this case the temperature gage goes up near the red spot or mark when is at 2500 rpm,I replaced the radiator fan I have not replaced the pump because is not leaking I used my compressor to clean radiator but still same problem any advice and any website to order parts? Please thank you. Jorge palacios from Orlando fl
Hello Matthew, I have an Oldsmobile intrigue, 2002, GL. I replaced the thermostat and the reservoir but now my low engine coolant light is staying on. It wasn't on before and my coolant is not low
Hey Matt, i have this same car, it overheats while driving it, and constantly loses coolant but i never see any leak or puddle under my car, not sure if i will have to do the whole process you just went through or is mine a different situation?
Matt I just bought a 2002 intrigue that overheats and see a lot of this buy only factory parts is there a way to talk to you directly I don't have lots of money to spend on trial and error and I want to talk to you about your time fixing this so I can better direct my mechanic
Did the GM Part's fix the problem? I have the same car and replaced the same parts still overheating The firestone complete auto care said Head gasket leaking Internally ??
crap I wished I would have watched this before. I could of just redo the gasket on the old water pump. Nope bought the new one and have the same problem as you.
It is very complicated engine with complicated computer. It is showing yellow color "CHANGE OIL" warning. There is very clean oil and only 100 km I made it. For to be sure, I checked the oil and it is very clean. I don't worry about this oil change light but water.
@@MattShaughnessy6 When you remove the thermostat I take it that is runs alot cooler but how much heat does it have inside the car? Only reason I'm asking is because I live in Michigan and winter is almost here and I dont want to freeze my butt off inside the car lol
The Shortstar V6 isn't a very good motor from blown cylinder heads to temp problems to so much more. I love the Intrigue though and found a first year model with the infinitely better Buick 3800 Series 2 V6. Olds should have stuck with this engine and the car would have sold many, many more. Sorry for your problems.
There have been issues with this engine and the v8 4.0 in the Aurora. My parents bought these cars brand new. You have change the oil, coolant often or the life is shortened. I remember the sales guy telling my mom to change the oil at 7,000 miles when it was brand new. I told her to get it changed way earlier.
