2006 Chevy Equinox Overheating

SO, I'm not a "car"guy. But I've performed minor work on previous cars, including replacing a few radiators. I recently bought an 06 Equinox, and the darned thing keeps overheating. I've checked all the hoses. No leaks. This SUV has a closed cooling system, with a 15psi release valve on the surge tank. I replaced the cap, because coolant keeps boiling out. This didn't help. I flushed the radiator, pulled it out, inspected it. It looks good. I went ahead a replaced the thermostat. Both fans seem to be working like they should. I can't drive the car more than a mile before it overheats, and boils out from the surge tank! What am I missing here?! Please Help!!!

    I used a Block Tester kit and it came back negative, so I don't think it's a head gasket issue. I'm stumped. I took it to the dealer, who said it was possible that the surge tank needed replacing. I don't see how that could be, as it is not leaking at all. Everything appears to be working correctly, except that it's overheating!

    O.k., when you checked the radiator and replaced the thermostat did you burn the cooling system of air?

    Have you checked to see what the actual engine temp is with a scan tool?

    no, i don't have a scan tool. It is supposed to be a "self burping system". since it doesn't have a true radiator cap, there isn't much else to do to burp it.

    It is not a "self burping" system. The cooling system needs to be open with the engine running at idle through at least one warm up cycle before installing the radiator cap. I suspect you have an air pocket in the cooling system from not burping the system.

SOURCE: 1991 camaro rs overheating

Flushing the cooling system has its drawbacks. I you needed one freeze plug, you can reasonably suspect the others are surely right close to failure.In this case, starting to fail one at a rime weakest first. Now, as far as the other issues are concerned. What is the question? Sounds like the tazmanian devil had too much time on hand. I don't know the qualifications or integrity of your mechanic, but I do know a reputable, as well asa professional mechanic is not likely to intentionally or even bother to, contribute to these describe issues. Ocassional blue smoke is an internal problem, The AC is an issue in itself, The caalyctic converter is an issue that is too messy, smrlly thing to deal with. Any evisence of how and of what it was gutted? What was repaired or listed as repaired on your invoice? And what state are you in? It appears you may be seeking legal advice and in this forum it would not be an appropriate place to seek it. You may want to refer this to an Attorney for assistance.. Good luck and I hope you reach some resolve on this matter.

Hi. A lot of work has been done with the engine. I guess all was left is the head gaskets. Try replacing the head gaskets. I provided you a link for better understanding. Please click here.

SOURCE: overheating I change waterpump, thermostat,

Sounds like your radiator fan is not doing it's job. At highway speeds, there is enough air flowing through the radiator to cool it, without a fan. On local streets at slow speeds, the fan is necessary to draw air through the radiator, else you will overheat. Check your fan, either clutch fan or electric fan, to see if it's working as it should.

Sounds like you need to disconnect the Radiators' electric fans and have them tested. You absolutely must have them working, or your car will overheat. Check to see if the Temperature guage is working.

You need to go to a good autoparts store and have them test the fans and charge and test your battery. You may need some sensors to activate the Radiator fans, but you could be running the battery down with shorted cooling fans.

There are also Relays which work with the Radiator fans. The overflow will stabilize once the water gets into where it belongs. Make sure your Thermostat is not clogged with the sealer.

Do the cooling fans come on ? Your vehicle should have two fans controlled by The PCM - engine computer energizing three different relay's for low and high speed .

Did you replace the thermostat as well? That could be your problem. Also make sure your radiator and reservoir are full.

I have a 2006 chevy equinox that has will not stop overheating and no heat. We have replaced the thermastat, sensors and radiator hose. We used that blue devil which worked for like a month but now ha


Needless to say you have not found the right shop yet.
You need to know if the water pump is pushing the coolant thru the system, is the system full of coolant and no air pockets, and is there excessive pressure in the system.
Do the radiator hoses and heater hoses get hot when the engine warms up ?
Are you sure the system is full of coolant ?
Do the radiator hoses swell up when the engine gets hot ?

1999 Honda Civic LX Stalling/Overheating!!!


(I don't know much about cars so bear with me).

I've had problems of overheating previously where my car's thermostat would hit 140. I think I've fixed the issue, I've replaced the thermostat but it was still doing that and 2 hoses blew and needed to be replaced. I've had to consistently fill my radiator with 50/50 antifreeze on a daily basis to ensure it won't overheat, so far that seems to be keeping the peace.

But now as of 5 days ago, I'm experiencing these new issues of stalling. Upon taking my civic into my mechanic, his meter showed that there was a misfire in the 2nd cylinder a month prior and now all 4 are misfiring. He thought it was the head gasket at first. I had just recently replaced the spark plugs with NGK Platinums, new spark plug wires and a new distributor cap.

I've received many possible culprits to my problem consisting of possibly the Throttle Position Sensor, Fuel Filter/Injection, Distributor or a radiator cap. I'm financially strapped at the moment and only could afford the radiator cap which didn't solve anything, however my radiator is running on 80% water at the moment. I'm really at a loss and I feel like I've done what I could and I'm at my wits end. Please help my poor little Civic cheat death for a little longer.

2006 chevy equinox overheating sludge in reservor and white smoke from tailpipe . is it headgasket or lower intake


hi.
unfortunately, sludge in the reservoir and white smoke does suggest a blown head gasket.
if the smoke smells sweet, then that will confirm that coolant is being burnt. take the car to a radiator centre for a pressure test, this will test the system and tell you where the problem lies. a basic pressure test should be fairly cheap. some places will do the test free of charge if you ask around. hope this helps

2005 chevy equinox do my radiator and condensor


Hello: You may have a cooling fan(s) problem. Start the truck, turn the a/c on max, both fan and a/c control. Open hood the cooling fan(s) should be running. If not then you will need hands on trouble shooting. It could be fan(s) motor(s), relays, relay control, ie PCM, wiring, fuse etc. Systematic hands 0n trouble shooting will be needed with a upscale scan tool.

Replace a key ignition out of my 2005 chevy equinox with a 2006 saturn vue now the chevy wont start cause of the theft system. how do i reset this


The 2005 equinox is equipped with GM passlock anti theft security. By replacing the ignition you have broken the communication for this system. Your vehicle will never start again until you fix that properly. There is a way to bypass that system so it will work. I've done dozens of these bypasses and they work great. Best part is you'll never have to worry about it again. Go to this link and read up on how this system works. The bypass YOU need is under "permanent fix". Trust me, this is your best bet. http://vatspasslockpasskeysecurityhelp.yolasite.com/
