Default 05 overheating

05 automatic 2.4. New fan, new headgasket, timing belt and tensioner, new temp sending unit, water pump, thermostat, radiator cap is not leaking, new relays, fuses pulled and checked, checked between AC condenser core and radiator and it is not clogged, radiator seems to have good flow. AC blows ice cold at idle and driving, temp gauge sets at half way. Drive 1.5 to 2 miles, AC on or off, and temp starts to rise and you can hear the overflow resivior bubbling over before the gauge gets to the red zone. Pull over and the fan is not working so I check the relays, low speed should be active at this time but power to low voltage circuit for the relay is not there. Waste a few minutes checking things, turn the key and the fan works again, by the time you are almost home it overheats again. Let it idle with the AC running, temp gets to halfway and stays there. Let it idle with AC off, cooling fan cycles as it should and temp drops to below halfway. Everything works like its sposed to till you drive it.

This kinda looks like another thread I have but it is a different vehicle, the other was an overlooked blown fuse. This new vehicle belongs to someone else

Sounds like a head gasket leak. Was the head checked before the new head gasket was installed? The tolerance for warping is only .004. One indication and an easy one is to open the radiator fill cap while the engine is running. Often you will see air bubbles as the coolant circulates.

First thing I would do a coolant pressure test. Make sure your coolant system is sealed.

If that is okay check your radiator cap. Make sure its working properly.

I had one doing that - Turned out to be a cracked head. I'm guessing that since the head gasket has already been replaced, it's the head itself.

After re-reading the original post, you may want to have the radiator flow checked. Since it's cooling back down at idle, you may have a flow problem. Can't move the coolant fast enough at higher RPM's.

The above are good ideas. I have had a very similar trouble with the PT Cruiser.

I also recommend retesting the cooling fan motor just to make sure, because when a cooling fan motor starts to go bad it can work intermittently (as I have seen on the PT Cruiser) due to the commutator in the motor. Re-verify both speeds of the cooling fan and try it multiple times with two individual separate wires direct from the battery. The cooling fan connector (the fan side) has three wires (ground, low speed, and high speed). Find out which wire is which and connect it direct to the battery testing low and high speed.

If none of the other tests find the trouble, I would also make sure that the catalytic converter is not plugged up using a back pressure tester on the port where the O2 sensor is (the engine side of the converter).

One other question I forgot to ask is does it overheat at high speeds as well as low speeds?

I was going to ask if it ever overheats with the fan on? Car obviously has a fan problem, so why go all in on huge fixes like the head when you can just wire up the fan?
