96 740iL - Running hot
my 96 740il runs hot after runing for a couple miles, the temp guage moves over toward the red and then return to normal after a few seconds, this happens continuously every eight minutes or so. I've replaced the thermostat three times and just replaced the radiator. The upper hose to the radiator gets very hot while the lower hose remains cool, this causes the overflow tank to boil over. What could be my problem and a remedy? PLEASE HELP!
