Car overheated again this morning, f*#k!!! second time in two days. yest i flushed the rad abd it seemed to run well all evening. woke up this morning..there was a patch below and to the left of the rad. temp was fine all the way to work(half hr) then when i was letting her idle i noticed the hot air going cold and temp increasing. then all of a sudden it went hot again and temp went down! whats goin on?!?!

 

Possible thermostat stuck in close position and not letting coolant through to radiator.Remove the thermostat and check if thermostat working properly or not.Drop the thermostat in a small pail of hot water approximately 80-90 C and see if thermostat opens or remain close.If remain close,then u need to replace one.
