I've got the part. Any tips/suggestions for installing the new Mono Valve in a '95 E320? Thanks

After you replacing your heater valve assembly start the engine with heater on for 20 minutes top off coolant as need.

I was wondering how much coolant I have to drain out before I start?

Don't drain any coolant, make sure the engine is completely cold first. Then remove the expansion tank cap and cover opening with some plastic, ( plastic bag will do). Replace the cap and proceed to remove the monovalve. The bag will act as a vacuum barrier so as to minimize the loss of coolant. After the instalation is complete, follow the instructions as to letting the car warm up with the defrost on high heat and then top of the coolant level after the car has circulated the valve completely.

I did it today. Took me a couple of hours. Probably should have taken my battery out, a little tight in there.
Just one problem, I think I put the rubber hose on the bottom fitting (the one that goes to the washer fluid container) too far on the valve outlet pipe and now the whole unit tilts backward. Bit of strain on the front rubber fastener. I hope that it will be Ok because to fix it means taking the whole thing out again. Any opinions? You can tell I am not a mechanic! |

I have a '95 E300D, (124 Body like yours) in which I replaced the Mono-valve and auxiliary water-pump last year.
I am curious. Is your Mono-valve and Auxiliary water pump ONE unit, or is the Mono-valve a separate component that you were able to purchase and replace on its own? In my case the Mono-valve and auxiliary water pump were only sold as a single very expensive unit Thanks Phil
