Engine overheating

My car keeps over heating when we drive over 10 miles. Also the air conditioner just stopped working. I don't know what the issue could be. We had to change to the light bulb and disconnected the fan by accident. The fans were reconnected and it didn't over heat for a week. It was also serviced about two weeks ago and they said it is a great looking high mileage vehicle.
Do you
have the same problem?

Does the cooling fans come on when its over heating? What could have happened is when the cooling fans where disconnected the first time and the engine was overheated it could have blown a head gasket.

Here is a guide to confirm the problem.

I changed the thermostat and my car did not overheat for two days. I kept air conditioner on and it worked great and drove it almost 100 miles and the temp gage stayed below half the whole time. Today my wife drove it 2 miles and it is over heating again.

Sounds like the problem is intermitted, has the engine been checked for a blown head gasket? chemical check the radiator to see if exhaust gasses are present and let me know.

I just topped the coolant off bc it was a little low and drove it for about 10 min. When I would stop at a light and idle the air conditioner would get warmer and then cool down again when I drove. Then when I got home I let it idle in tje drive for a minute and the engine started to climb in temp. I dont smell anything burning and we just had a 100000 mile service done and they said everything looked great.

My car is overheating like all the other equinox I'm seeing online. I've done everything including head gaskets. Still overheating. Has anyone come up with a solution. Other than getting rid of it?

Are both upper and lower radiator hoses getting too hot to hold?

I have a 2006 Chevy Equinox, everyone says to inspect oil residue to for possible damaged head gasket, well my question is what are we supposed to look for if using Dexcool? Is it still a milky substance? Reason being, I want to use process of elimination to diagnose an overheating problem as well as intermittent heat flowing into vehicle while driving. I had the cooling system diagnosed and thermostat replaced. Problem is Equinox still overheats while driving, fans do come on.I also hear gurgling sound on take off from a stopped position. There is a bleeder screw right on top of water pump, at least that's what it looks like, I just don't know the process of burping an Equinox, it has no rad cap.I know the process varies for different vehicles. Help me and thank you in advance.

If it's blowing the fan fuse, the fan motor itself could be bad.

It's probably still bad and not running fast enough. It blew a fuse for a reason.

Would a new radiator cap help the bubbling and smoking

It sounds like the fans are bad. A radiator cap will not solve the problem.
