it happened to my 98 as well, turned out to be the reservoir cap... just tighten it a bit more or have it replaced, there are some recalls I think.

This was my problem also. I replaced the cap with the newer part number and all is well!

first try new part number cap (cheap and easy)
also, check where its leaking, i accidentally ran over a brown bag that had a bottle, and put a slit on the rubber hose on the bottom, and leaked out.
can be a few things, and like mentioned, those reservoirs are prone to leaking...
good luck and let us know

I also have a "leak" or more like evaporation of coolant... I tracked it down to bleeder valve.. it's closed.. but vapors are still coming through.

Should there be a gasket on bleeder valve? I took it out. and to my surprize there was no gasket there..

If yes.. can anyone point me to part nr.. or where to get it?

Thanks
Sasha

coolant leak

Coolant cap, coolant line, coolant tank, water pump going, heater core, ac drain.
Simple process,......have a pressure test done at the dealership from the coolant tank.

I'm having a coolant problem in my 03S as well. Two weeks ago my low coolant light started blinking and it's been losing coolant pretty consistently ever since (coolant light will go off about 3-4 days after topping off if I don't keep up it with). I tried replacing the cap without success.

Today I finally took off the under panel to get a good look at it. The location of the leak seems clear, although I couldn't get it to leak as much as it has been. Pictures are attached. Thoughts? Does the water pump need to be replaced?

Best,
Greg
