i need some ideas.
recently my 95 v-6 contour has started to overheat only at hi-way speeds. while driving my gauge will slowly keep rising all the way to hot. if i stop and let it idle the temp will quickly drop from the red area on the temp gauge to the "o" in normal within 30 seconds and stay there forever if all i did was sit there idling. as soon as i get driving down the road again the temp slowly starts rising.
it takes 3 to 5 minutes to get back up to the hot range. if i put the car in nuetral at cruising speed it will cool right down then too.
the car starts fine and runs fine. no strange noises or smells. i am not leaking coolant or anything else and the heater blows hot air.
i am not the most mechanical person i just need some ideas so i can hopefully avoid a disaster , unless i allready have one.
i have fun in my contour and want to keep it going. thanks
