We have changed and cleaned everything. There is no evidence of a head gasket leak, but it keeps overheating.

Hello again,

Okay, can you please check the serpentine belt and make sure it has proper tension and is not misaligned. If there is a problem with the serpentine belt it would slip and not spin the water pump at the correct speed causing your vehicle to overheat. Please get back to us with what you find out.

Thanks,
Alex
