If the car overheats at slower speeds or idle it's most likely an airflow problem. Like your cooling fan(s) not working properly or a radiator that is blocked in front with leaves, dirt, etc. If this happens at higher speeds you have low coolant or a cooling system that is dirty on the inside resulting in poor coolant flow through the engine and radiator. One other thing to look at is ignition and valve timing. If either are retarded (late) this too will cause overheating because your engine is working harder than it needs to. Timing becomes suspect if the car has high mileage. The timing chain may have "jumped" causing the retarded timing issues. HTH. -Jim
