ok this may sound strange but after driving my 1993 z28 camaro and parking it i can smell antifreeze. it is not dripping any where from where i can see. im not losing any coolant because i check it evey morning beforu i drive because of that. i was just wandering if any one else experienced this before or know what it could be. thanks.

 

Can you smell it in the exhaust? check all smaller lines (i.e. heater hose lines for small cracks). You will see a yellowish dried up residue on hoses that may have very small tears, which will eventually burst.

 

It might be so small a leak you won't notice the level going away. I know on my car, the t-stat housing was leaking ever so slightly. Couldn't see any puddles, because it would evaporate off once coming into contact with the hot engine. Only way I found it, was while inspecting, every so often you could see a wisp of steam coming from that location. Just enough to give a smell of antifreeze.

 

thanks you guys. i think it is a yellowish residue on the upper radiator hose but i will check again.

 

A similar issue here, only that right at 180 deg I would get a waft of sweet smell inside the car then it would dissipate. looped to by-pass the heater core and still the same situation. 98 3.8l (p.s. is there a weep hole for this type of water pump?)
