I own a 1990 190e Mercedes-Benz, after it has run for a little while, it starts to leak water on the passengers side, behind the heater, which leads to the car over-heating. How could I fix this?
This is your heater core leaking. One thing you can try is some of the stop leaks that the auto part stores sell. I would try "Liquid glass" as the heads on these are kind of delicate once overheated. This may also stop any other damage occuring(like leaking headgaskets). The only other fix is replacing the heater core.
