For the last couple of weeks, my car has been overheating when I have turned on the ac. I checked my reserve and it was bone dry. I filled it up, and today, it was bone dry again. I was leaving my car when I heard my reserve boiling. I had a new radiator put in last year because it was cracked. I think it might be a head gasket problem, but I'm not sure. Any more info? It would help a whole lot. it's very stressfull

 

ya sounds like a head gasket to me. same thing happened on a coupe i used to have. the resevior will boil over then when it cools down its bone dry. thats a head gasket.

 

Fill not only the reservoir with coolant but also the radiator. Also consider replacing the thermostat and radiator cap and then bleeding the cooling system.

With respect to a possible blown head gasket, you may want to compression test the cylinders and do a cylinder leak down test.

 

Sorry about not mentioning that I did fill up the radiator with coolant. Can anyone send a link on how to remove/replace the head gasket?

 

its super easy. get a repair manual or search for it here. also search about the blown headgasket youll see lots of people have the exact same symptoms as you i did too. the most important part of doing a head gasket is the torque sequence and specs. also if you overheated it really bad make sure the head and block arent warped. thats usually not a problem though.

 

the culprit was the radiator cap. It was done. Thanks everyone.

 

Bad news it still goes up in temperature when i come to a stop. Any suggestions? The water is fine. No boiling in the reserve.

 

Does the fan run?

 

Yes I am going to change my thermostat and bleed it now

 

Which fan do I check? Would a bad fan cause those symptoms? It doesn't overheat when I have the ac off.

 

Just wanted to note that the temperature goes up when I stop and when the ac is on. Maybe the fan?

 

You have two fans, one behind the radiator and one behind the A/C condenser. The radiator fan should run when the engine is hot, whereas the condenser fan should run whenever the A/C is on.

 

Ok here is some more news. I am leaking a whole lot of water when the ac is on. I open the hood and saw it's coming from a little tube. Also a loud screeching will occur. Possibly my water pump causing all this mess?

 

What little tube?

 

The weep hole possibly.

 

The leaking water may just be water condensation produced by the A/C when it chills the air. There's a drain tube below the evaporator on the front passenger side of the car. The loud screeching may be a loose A/C belt.

 

There is a fluid dripping from my exhaust.
