When parked with the engine running, check the fan. When the engine overheats, the fan should turn ON. If it doesn't turn on, the problem is probably the fan or associated circuitry. The fan motor may be disabled (fuse, bad wiring, bad motor, fan thermostat, etc. . . ) When the car is moving, the air is forced over the radiator, cooling the engine. im not a mechanic by formal means,but it might have something to do with the thermostat function. its (possible) that its either old or defective. as you operate your vehicle heat builds in in engine. oil in the block and coolant in the system keep it from excessive heat build-up. the thermostat opens when a certain temperature is gained.if it can't open or close properly,it might cause problems such as you have stated. have a qualified serviceperson check your vehicle as they have the equipment to diagnose the WHOLE system. Good Luck!

Why does your car die while driving it loses all power suddenly and takes a minute to restart?
To give more info, the car surges before it dies. I can actually keep the car running if I tap the accelerator when I feel it surge. The car also dies at idle. I don't know if this is related or not, but the car easily overheats even with new coolant and thermostat.
If car overheats can it catch on fire?
YES
