the car I have is overheating. I replace the water pump, coolant tank, radiator, thermostat, top n bottom holes to radiator, checked the lines/clear. car is still running hot. even when its just sitting there idling. before I changed the water pump and radiator, I could drive it under 45mph and leave it idling without it overheating. now just sitting running, it overheats. help?

pressure check for a head gasket leak also there is a chemical additive you can get at auto parts that will detect a leak.
