There is _no_ way coolant could get into your windshield fluid reservoir... not unless somebody confused the two (would probably explain the overheating ). There is no "coil" - the thing you are looking at is the windshield fluid warning signal sender.

There is a coil inside the windshield washer reservoir. That coil heats up the washer fluid to help clear the wind shield during cold weather. The coil is heated by the coolant that passes through that coil. So, there is a possibility that the washer fluid mixed with the coolant due to a leak in this coil.

just tie the two lines together since hot windshield fluid does me no good here .

Yes you can bypass the heating coil by connecting the two coolant lines.

COIL

Yes you can bypass the heating coil by connecting the two coolant lines.

The coil is easily removed from the washer tank. A used coil is cheap at the junkyard. The solder cracks after years of being soaked with BLUE washer fluid. Use a non-corroding fluid that will not eat up the solder. Sold at dealers or other aftermarket sources.

In '89 MB moved to the heated washer reservoir. They also used heated (electric) hose from the washer res up to the nozzles on the hood. They are both problematic over time. I have 260k miles on my '88 300E (which doesn't have any of the heated washer parts) and I have never missed the effects of heated washer fluid. You could go to a boneyard and get a pre '89 set up.

All of the responses are correct except this one. He probably never had one with the heated washer reservoir like yours (that failed). Like everybody else said: it is simple to bypass or get the part from a salvage yard. I have done both..

Simple hose bypass

..it is simple to bypass ..

I bypassed mine for now, easy to do, 6 inches or so of small hose, two worm clamps..
