Car overheating - help!

ok thanks

Just came back from a short spin and when I got home the temp gauge was at 3/4 and going north, I switched everything off just before it hit red. I looked under the hood and no obvious coolant leaks. The top hose was very hot and hard while the bottom hose was cold (not even warm) and hard.

The waterpump was changed 15K ago (metal impellar) but the thermostat has never been changed.

The car has 70k on the clock and had never run hot before.

Any advice much appreciated!

I had the same problem and mine turned out to be my radiator. New radiator ran me $189 with free shipping. After replacing it, my overheating problem was solved.

Thanks again to everyone, I will change the thermostat first, if the problem persists then the rad is next on the list.

Don read this thread, take note of post by EMW525E34 about taking the top hose off and back filling the coolant system. I had exactly the same symtoms as you and this fixed it for me. Air in the systom for sure!
