like every member on this forum. ive had a few overheating problems. ive did compression checks. changed caps and thermostats. flushed and burped the system over twenty times in the last few months = $100 plus. anyway, my next thing was to go ahead and upgrade the radiatior. and if that doesnt work , then next would be pulling the head because i was tired of the engine heating up and i have to keep check the coolant level.
my car doesnt overheat in any pattern. sometimes it only happens once in a while , sometimes once a week, a few days , or everytime i drive. it never happens when just idling.
while checking out my new lex afm i was under the hood revving the motor i suddenly heard a loud suction and i look over to see that the upper radiator hose have collapse(flattend out). it held in that postion for a few seconds then released. i was'nt even revving it hard. i tried to do it again but it didnt work.
later i was at auto zone with my hood up and car idling. suddenly the upper hose collapsed again. this time the car have been at a stand still for a good ten minutes and i WAS'NT revving it.
I think that i have finally found the weak link in the cooling system. my theory is that during idle it never collapse because of not enough suction from the pump but at drving speed 2k+rpm the pump sucks the hose close caution the car to overheat. but by the time i pull over the hose reopens but its now too late and the car is already too hot and now spittin coolant through the resevoir. my car does it once in a while in no particular pattern so this is the only explanation. so thats why they make hardpipe for the upper hose. my upper hose looks fresh but when i squeezed it was soft.
i advise every that is overheat spuraticly and have no idea why. check the upper hose not for leaks but softness.
anyone know where i can get a decent hardpide for less then the price of my car?
