Yeah, I was thinking that too, until I opened the radiator and its full and the overflow tank has fluid in it also. So where would the air be in the system and how do I get it out?
 
My wife took the rdv out today and its near 80 here and she said she never had one lick of issues with it acting like it wanted to overheat. It seems extremely random and mostly when I have my boat hooked to it. Funny thing is I don't even have to actually drive it anywhere. I can hook the boat up, fire it up in the driveway and just let it sit and run and the gauge will just keep getting higher and higher. I am almost wondering if its not an electrical issue and when I hook the wiring harness to the boat up if that is somehow playing a roll in it. Whatever it is I am sure clueless as where to start.

If there is air in the system, there is two bleed screws to get it out. (don't know where they are as I haven't had a need to look for them)

ms_v,
 
I am sorry to read about the multiple trips you have had to make to get this overheating concern looked into. Have these all been made to a local mechanic, or to one of our dealerships?
 
If we can look into this further with you, please email us at socialmediagm.com (include your name/Edmunds username, phone and address, the last 8 digits of your VIN and current mileage and the name of your involved dealership) and we'd be happy to do so. My coworker Christina, who answers inbound emails from the forum, will advise you further.
 
All the best,

I so agree with you there........... I have had it with is GMC. It sits in my driveway more than on the street because of over heating! I have had the intake gaskets remove twice and now on the 3rd set, new water pump, new belts, new transmission......now... I am looking into the fans because they are not keeping the car cool down!

The T-stat is fine... It has been sitting in my yard because of money to repair it again. I hope to get it fixed this weekend. I need a car! I have replaced the transmission, water pump, battery, belts, hoses, and this weekend the intake gaskets again...this will be the 3rd time! I am also looking into the fan system. This may be the major problem with the car....Thank you for trying to help me.... if you have information on the what to replace on the fan part please let me know what to look for...Thanks Kathy

I don't want to assume anything, is it actually getting into the red zone on gauge or just close (in particular while in slow/stopped traffic)? One quick way to tell if fans are actully working is to turn on the A/C, both fans should quickly turn on. Could also be temperature sensor/connections are not working correctly.

Hi... I have had the overheating problem since October. It has always been very warm under the hood, and I have the telltale melted paint under the hood, but I have never seen the temperature gauge go over the halfway mark. Suddenly one day, the car completely shut down while driving on the highway. The Hot Engine warning light came on, It was a warm day, and the car had been idling for awhile before driving. I was also running the A/C. Then the weather turned cool, and I didn't see the problem for several months. I keep the reservoir full will DexCool, although there is a lot sludge in it. Now the weather is heating up again, and I'm getting explosions of DexCool from the safety valve almost every time I park. I have DexCool all over the engine, the inside of the hood, and leave a puddle of the coolant wherever I park. And even after a short 10 mile drive, it sounds like the engine is percolating (like every bit of fluid is boiling) after I stop. It is scary. I'm a single Mom, and this vehicle is my lifeline. But I also can't afford to pay thousands, or even hundreds for a repair. I have had the car for 6 years. Also, about 2 years ago, I noticed the speedometer occasionally dropping down to 10 or 5 while driving on the highway. It has gradually gotten worse to where now it occasionally reads the correct speed, but usually stays at 0. That seems to be a common issue with the Rendezvous. What kind of repair bills will I be looking at? I was told that the overheating issue was a problem with the engine heating core, not the radiator. Dunno.

If you have coolant all over the place in engine compartment I would suspect a hose that's leaking, This will quickly lead to low coolant and overheating that can do some serious damage. You also need to check coolant level in radiator by removing the cap (while cold), the reservoir fill isn't going to be good enough.

dolfinity,
Thank you for taking the time to post your experience and concerns. I would recommend speaking with a GM dealer, even if its only to get the concern diagnosed. Please feel free to email me directly. Any updates on your concerns are appreciated.
