My car runs hot, and I add antifreeze, it runs fine and then the antifreeze

(1999 Pontiac Grand Am)

runs out and overheats again and I have to add more antifreeze. It has done this for the last couple of months now. What is causing this??

If you have the L4 engine, check around the driver side of the engine to see if it's wet/sticky/sweet smelling. There's a black piece with hoses connected to it - it's the thermostat housing. I know from personal experience that these are made of crap plastic - I've had to replace mine twice. These pieces only cost about $20. :)

you have a coolant leak and needs to be repaired asap. your constant overheating may have caused considerable damage to the internals of the motor complicating the repair.
