My 99 ford taurus is still running hot. I have replaced the radiator, the thermostat, the starter, the battery, all within the past month.I have flushed the system 3 times when I replaced the radiator. Now it still runs hot when I turn on the A/C or when I drive it for more than 20-30 mins. There are no leaks and it has plenty of coolant. Both fans are working. Also my A/C won't run on low, only on high I have replaced the A/C fan and the receptor in the glove compartment and it blew on low for 2 min then stopped. I don't know what else to do!
