MB Master Mechanics: Need your opinion on heater core leak
 

I tend to agree, based on feedback I've received, that the mystery hose is the drain from the leaking heater core in my SL500 '95. Here's my thought for the quick fix. I don't drive it in cold weather (in Cleveland it snows too) so I would like to know if the two hoses that run of each side of the rear of the motor and into the bulkhead/interior, are the heater hoses and if I cut them and ran a bypass, if that would be an acceptable way to stop coolant leaking out the drain, at least until I can find a way to repairreplace the heater core myself (this entails someone providing me step by step instructions and maybe some pictures for reference)

What do you all think about this temp solution?

thanks, Steve

Heated seats? Mine will make you hot.

I've use the by-pass for block to block in engine compartment to avoid this many times on many different vehicles. Will always work until you can get to a permanent fix.

Is FL an option? ;-D

'95 SL500 Heater Core or Evaporator Leak Update
 

I posted the original question last year, thought I had a heater core problem. The problem was actually a leaking evaporator and I was seeing the dye/oil leaking through the discharge hoses by the tranny. Replacing the evaporator is a major time consuming job a tres expensive. Instead, I discovered a product called Cryo-Seal made by SSR Int'l and had it installed by an independent. About $195 for materials and tech time to flush and replace some other components and add freon. About 18 months later, air works fine and no signs of visible leaks. Steve
