Just got a 2002 "S" and I've noticed a small amount of coolant puddling under the car overnight. I've tried to see where it is coming from but it is so darn crowded under there I can't see where it is leaking. Looks like it may be up in the front of the engine. My guess is the water pump or thermostat. It does not run hot at all. I try and do all the work myself. Are those fixes hard to do? Is there a good repair manual or CD I should have? I do all of the work on my 1981 928. Thank you for your time.

 

Check the tstat neck thats common trouble with the first gen

 

Thanks Venge. What do I have to take off to see the thermo neck?
