Winterizing with compressor
Hi,   Happy holidays to all🎅🏻🤶.We are the proud owners of a 2017 MB, love it. Have a question on winterizing. In speaking to a friend he said there should be a cold, hot and bypass valve for winterizing . LD doesn’t seem to have valves, unless I’m missing something . The Manuel does explain to hook up compressed air to water pump etc. If you hook up air to outside water inlet and blow system out, after draining water heater, will you get the same results. Newbie Thanks

You will end up leaving some water in the system.   I believe it's the line running from the fresh water tank to the pump but am not certain.  It's best to follow the directions in the manual.    Frank

Frank nailed it. There is a filter basket before the pump, the line between the basket and pump, the pump, the line after the pump until the two lines meet.  Those need to be cleared of water.  Follow the manual’s procedure and you will clear everything. Deavate and you are likely to miss something that will later freeze and cause trouble.

Question, Does the windshield washer unit on the E450 need any kind of winterizing? Does windshield wiper fluid have any anti freeze capabilities? I can believe that the plastic lines have enough flexibility to survive but what about the nozzle or the fluid tank? Would appreciate your thoughts.

"Does windshield wiper fluid have any anti freeze capabilities?"

If you are going to be in a situation where freezing temperatures are expected, then yes, precautions are in order. When you purchase WW Anti-freeze inspect the label closely. Make sure that it will protect your WW system (pump and tubing) to a temperature below what you expect to encounter.

I've encountered frozen WWs and if it happens to you it's a sure bet that you will not be driving any time soon, or until the defroster can overcome the problem.  :(

Compressed air is simpler than you would expect. Pulling out the converter a few inches really makes the whole job much easier. Allows for easier access to the water lines.

Is window washer fluid really an issue. All the years I have owned vehicles in the North have never had as issue with window washer systems.

Windshield washer fluid comes in two types - one made to be safe in sub freezing weather since it won't freeze, and one that shouldn't be used in sub freezing weather since it will freeze.   You would think the appropriate fluid would be sold in cold climates but this isn't always the case so check the label before buying if you have freezing weather in your part of world.     Frank
