Re: [diesel_mercedes] Coolant running out of 116

 

Well if that's the deal, then not overflow tank or hose , have to be heater or hose running to heater. Max

I understood the coolant was coming from the drain on the firewall.  The one that often gets clogged with leaves, causing water to fill the front passenger floor.

Not a good description but it sounds like it could just be the hose to the overflo tank.? If it is it could mean the radiator needs flushing or replaced?  How about a picture? Max

From what you're describing, it sounds like coolant is coming out of where the a/c condensation drains out.  That would indicate a possible leaking heater core, or, more likely, a short hose that connects the heater core(s) in the passenger compartment to the cooling system under the hood.

You can get a better idea of what goes on in there from the factory service manual at the W116.org site:

We have a problem with my wife's 1980 300sd leaking coolant. Yesterday, she called and said that the car was was overheating. After numerous stops to refill with water, we finally got her home. Found that the water was coming out of what appears to be an overflow tube on the passenger side of the firewall. This tube is 1-2 inches wide and outlet is made to remain closed but will allow fluid to come out if needed. Don't know how water could get from a closed system into this "overflow" tube. My Haynes book does not show anything and I could not find any pictures/diagrams on the internet. Any suggestion or advice on how this works or how to fix this problem would be appreciated. Thanks Tom.
