no coolant or you have a bad thermostat and or bad water pump .

msmaylum@aol.com Coolant could be low. Thermostat could be broken.

Water pump or fan may not be working.

TURN ON YOUR HEATER; OPEN YOUR VENTS TO HELP COOL DOWN YOUR ENGINE.

IF IT'S TOO SMOKEY, PULL OVER, POP THE HOOD UNTIL IT COOLS DOWN

THEN OPEN HOOD ALL THE WAY. WAIT A FEW MINUTES BEFORE YOU TAKE OFF

THE RADIATOR CAP, BUT WHEN YOU DO, USE LOTS OF CAUTION. STEAM IS

VERY HOT AND WILL BURN YOUR FACE AND OTHER PARTS OF THE BODY. WAIT

A LONG WHILE BEFORE OPENING CAP TO RADIATOR.

I had a 2002 Vauxhall Corsa which was running hot and it turned out

to be the water pump which needed replacing.

Causes for an overheat: low coolant, failed water pump, plugged

radiator, failed headgasket, inoperative radiator fan, stuck

thermostat, missing belt, etc
