My guess is that your water pump is dying. Has it been replaced yet? Best thing is to tell your daughter or whoever drives the Acadia is to stop driving in an event of an overheat.My daughter just called coming home from school in my 2010 Acadia and she sd it's overheating going all the way up to 250 when she got home I checked all the fluid levels (coolant, oil) and they are fine.. haven't figured out how to check the radiator I am female and my dad taught mi on older cars when things were much easier to do.. but the fans were running and I've had it off about an hour looking up different options or answers.. now it's time to get my other kid from school and my husband isn't due home for another hour I need a quick fix or if someone knows what is wrong so I can tell him when he comes in would b greatly appreiciated!! Thanks!!
That's the best place to check your coolant level. The cap is under the flat shroud in front. Remove it only after the car has cooled down. Make sure the radiator is full and fill the coolant expansion reservoir to the 'Full Cold' mark. It should be OK after that. Be sure to use the proper coolant. Factory coolant is called "Dexcool." You can save some time by purchasing the 50/50 Dexcool-water mix.... haven't figured out how to check the radiator ...
What kind of guarantee did the insurance company get with the used engine? It's a shame they didn't offer to replace the flood-damaged engine with a remanufactured unit.... now my engine is DEAD will not start the battery is dead and now i'm fighting with insurance.
Some of the online fault code descriptions lead to a possibility the PCM is failing. Someone with a good diagnostic scan tool and knowledge of how to use it could determine of that's the case. Seems like a better option for you to find that someone than just throwing parts at the problem....
Any suggestions on next move?
I am reading this overheat situation, even though it is an old thread, my 2011 Acadia which I just installed a 34,000 mile new engine in from a 2015 Acadia runs at 210, when it was 104* outside I ran it up a local mountain. Goes from 500 ft elevation to about 2,000 ft in about 3 miles. The temp rose to over 220 in that short climb, unloaded car and only the driver on board. My other cars I work on stay right at the thermostat temp. The Acadia seems to vary frequently between 195 and 210 in normal driving in cool temps. It only climbed over 210 to 220+ when it was 104 and I worked it climbing a hill. Is this normal or do I need to go back and burp air from the cooling system? ThanksI recently encountered a major issue with my acadia overheating. I am wondering if I am the only one! I have about 1500 miles on the vehicle and I was driving back from thanksgiving break. After sitting in traffic outside of New Jersey (45 degree weather) for about 20 minutes I noticed my temperature starting creeping up to 220. It normally runs near 210 degrees. After ten more minutes, the temperature was at 250 degrees, but I was sitting in traffic with no where to go. When the temp hit 260, the car went crazy.....the traction control kicked off....the service engine light came on...and the car went into a reduced power mode. I was able to pull the car off the turnpike onto a service road and tried to get On star to help me out. They were anything but helpful.....told me to take the vehicle to the nearest dealership on a Sunday (sure they will be open) while I was 400 miles away from home. After letting the car sit for about an hour...it cooled down. I checked the fluids....oil and coolant levels were fine. Anyone else have this happen. My acadia is now in the shop and I have a feeling they will not be able to find anything.
