My '92 190E (2.3) has developed a significant collant leak. It appears to be coming from rear of the engine, so I immediately thought that it must be a heater hose -- but the heater hoses are fine. In fact, all the hoses seem to be fine.

When I let the car idle in the driveway, it doesn't leak. It also doesn't seem to leak when I drive it. But after I park it (after dirving) and it sits for a minute, then the leak starts.

Where should I be looking??? Any insight is appreciated.

Thanks in advance.
