car shutting down when temp above normal

Have the cooling system serviced before you ruin your engine. Thermostat, flush, new coolant, hoses and maybe a new radiator and water pump. Also make sure the cooling fan works.

If you alreafy know it's heating up, don't use it til u find the problem and fix it, these cars are notorious for head problems due to overheating. Start by replacing thermostat and new coolant. Start it up and turn on A/C, the cooling fan will turn on, this will tell u if fans are ok. If you notice fans not kicking in when temperature raises, check the cooling temp sensor (switch)
