Re: Car losing coolant!! Overheated help!
Fill the radiator and reservoir with coolant, and let the engine idle for a while. During this time, watch for coolant leaks from hoses, the radiator, and the weep hole at the bottom of the lower timing belt cover (water pump), or simply boiling over of the reservoir. Also look for white smoke from the exhaust pipe. Note whether the fan turns on when the engine is hot and whether the lower radiator hose remains much cooler than the upper one. Never let the dash engine temp gauge read even 3/4 HOT.
