Leaking coolant
 

This morning I went to the garage and found a puddle of antifreeze on the floor. My 190e 1992 had sprung a leak. It appears to have come from the back of the motor near the tranny. There is a line there that leads to the firewall and goes into a smaller rather clear plastic line maked 1400 that goes into the firewall. It appears to have come from that line. I put it on ramps and let it run for a while and it did not leak? Any ideas?

Someone will probably chime in with info specific to you car.

In the meanwhile, I've had the best luck with using a pressure tester. I bought one, but I understand that some auto parts chains will loan or rent them. If you can get your hands on one, it'll help immensely.
