1996 S320 hose part numbers needed
 

I have a 1996 S320. someone bypassed the whole duovalve-heater system. I need 2 hoses, one that goes from the water pump into the duovalve, and the other that goes from the firewall back into the engine. does anyone know what part numbers I need? Maybe a photo of what it is supposed to look like?

I looked on EPSnet, but I can not identify the correct hoses there-- the diagram is a bit confusing.

any help would be appreciated!

once I hook it back up, I'm afraid of finding a bad heater core or duovalve , but I guess there is only one way to find out!

thanks.

Suggest calling the Parts Department at your local MB dealer and asking for the part number and price for each hose.

The parts guy had the same problem trying to decipher the EPS diagram. I think I'll see if one of the techs there can help.
