well i just got home from my little trip and about 3 miles away from home the temp gauge started going up. well when i pulled into the driveway it was almost touching the red line. parked and then all the coolent started leaking out. let it cool off and popped the hood and it came all from the radiator cap. here is my tech question, how do i diagnose what the problem is. im thinking either bad water pump or thermostat. how can i narrow it down to what it is. thanks guys.
