I went 2 a shop today and they say it could be the hydraulic fan thats making the car overheat but the fan comes on and plus it kicks in harder once the car start overheating like a buzzing sound when u accelarate. They did a chemical test for a head gasket it came out good and plus a new water pump was put on and thermostat and a flushing. Im tryn 2 see wut it could b cause I think they know. Especially with the fan
Given the test results and dandy observations, if the overheating occurs gradually you might suspect corroded cooling fins on the radiator. That will reduce the radiator's ability to give up the heat to the air. A valuable clue is the coolant temperature will come down if you run the heater on the highest temperature and one of the higher fan speeds. The heater core is a small radiator and can give up heat pretty efficiently.
