Question about 2008 GMC Acadia

2 Answers

My 2008 Acadia is overheating. About 6 months ago it overheated but cooling levels were fine. Nothing was repaired and everything started working as expected. Yesterday, it started overheating again. I tried reseting the ECM computer but that did nothing. Once you crank the engine the temp immediately goes over 210 which is the normal temp level.

It sounds as though your acadia may not actually be overheating, it sounds more like the tempeture sensor is bad, if its "froze" at a certain reading this could fool your computer, you should be able to replace this part for around 20 or 30 dollars. hope this helps

My 2009 gmc Acadia fan was running a lot more lately after shut off and then last night it said shut car off and when restarted was in reduced power mode when I checked coolant it was almost non existent...


A very common issue on the 3.6 liter V6 engine in the acadia is a leaky water pump. The pump starts leaking, causing a low coolant level, causing the engine to go into reduced engine power mode to keep the engine from overheating. This usually results in a very extensive cylinder head gasket repair job. You should have a local shop perform a cooling system leak check to find the leak for sure, and an engine block check to see if the overheat condition caused internal engine damage.

Best test,,NAPA sells a combustion leak tester(balkamp #700-1006) A tube of liquid that will change color if combustion gas is in the cooling system.Thinking you may be right about a head gasket problem or possibly a crack in the head.
It comes with instructions and is cheaper than having a shop guess at the trouble.

2008 GMC Acadaia overheated, and dinging sound won't stop. Coolant was empty (small leak I didn't know about) so filled the tank. Car has been sitting for 2 hours, and the dinging is still happening. ...


Are there any check engine lights on the vehicle? Is it dinging with the key in and the vehicle started and all the doors closed? Once I have more information I can assist you further. If you have enough coolant in there and no damage was done from it overheating too much/ too long it should be fine to drive.
Thanks,
Lee

II have a 98 deville changed thermostat 3 months ago,started overheating yesterday after i checked my coolant level


The most common overheating problem with the Northstar engine is a blocked purge line. It's job is to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.
