Hi all,
'92 Spider:
Stopped at smog station aftwer a 4 mile drive. all well on board.
The car ran idle wfor about 10 minutes while the tech filled in forms. He started the visual and discovered a drip of coolant from the front (about in the middle). I could not see anything obvious around pump, hoses, radiator. Overflow tank level about halfway F&E, but tank seemed pressurized. He didn't want to do the smog because of the malfunction.
Filled Coolant bottle completely, drove home.
Left car running, bottle still full. Car ran idle for 20 min, throught several fan cycles, but not a trace of leakage.
All I can think of is the filler cap doesn't vent out, builds pressure, causes a leak?

Any experience/thoughts?
