Google Patents US7216818B2 - Windshield washer fluid reservoir tank device for vehicles PS: I have included photos of the gasket for anyone who reads this, in case they want to make their own to improve on what the dealer offers.US7216818B2 - Windshield washer fluid reservoir tank device for vehicles So my question is, does part #110 seal to the tank with a simple O-ring, or is there more to the joint to make it water tight? It seems very poorly designed. After re-assembly, the pipe area leaked exactly as before.ĭuring this effort, I did not pull the entire accordion hose (#110 in diagram, PN A230 869 01 17) all the way out of the tank since I did not know how it seals itself to the tank (it seemed awfully loose). I cannot see how this setup would be water tight, but okay, I installed it (fighting the urge to use silicone to seal it). The foam gasket looks very flimsy and came with some creases in it. I ordered one from the dealer thinking that would be it. After reading this thread and above quote, I thought the problem was probably the O-ring gasket in the accordion pipe that joins the filler neck to the tank (#115 in the diagram, PN A2).Īfter inspecting the pipe, I found that there was no O-ring in the joint (where it went, I have no idea), so I assumed that was the culprit. I have had the same symptoms for a while in my SL55 AMG, i.e., about a pint of water runs out the bottom of the car after filling the reservoir to the top. so the connector from the tank to the filler pipe would be the number one suspect (#110 in drawing, A230 869 01 17 ), or, there is a gasket between the filler tube and the connector (#115, A2) and the level switch has a grommet (#100, A2).Hello. I just re-read your post and it makes sense that if you never get a low fluid light that the leak is at or above the sensor. Should have also ordered filler tube and grommet mentioned in one of the posts. ![]() ![]() I am not sure if leak was from the filler tube connection or from heating tubes' seals, but either way it is only possible when tank is completely full. No need to remove the grill itself, it is just that these screws protrude inside and get in the way. To make the job easier start by backing off two screws holding black grill in the right front fender. If you need to disconnect pump connectors - put small screwdriver into the opening on the side of the connector and push the handle up, tip will press down and away on the tab inside disengaging it. Then wiggled the heater out of the tank (be careful not to sheer off the level switch inside). Then pulled off hoses leading to the windshield and front bumper. After that I just removed the entire tank with all attached stuff. First I opened the cap with heater hoses, so the heater was loose inside the tank. There is no way to pull the pumps up as directed in the step 3. I totally do not believe that it can be done per the WIS above. It did not work at all, and on top of this, the fluid leaked when I tried to top off the tank. I just replaced a windshield washer pump in my SL. AND yet, it did not have a windshield washer bottle because it did not have squirters (an option the original purchaser passed on) ![]() my 65 GTO (I bought when I was 15) had so much room in the engine compartment, you could nearly sit inside while adjusting the carburetors. they did not fail much during the warranty period making it a design success by Mercedes standards : )īy contrast to vehicles of old. it does maximize otherwise unused space to provide a longish-term supply of not-frozen windshield cleaning fluid. "Īs to the gratuitous complexity of the bottle. HCS (SRA) pump (M5/2), replace if necessary. "Check rubber grommets on windshield washer fluid pump (M5/1) and The R & R document refers to grommets, etc that should be inspected/replaced Removing the fender liner should allow you to observe how full the tank can be without leaking - which should indicate where the leak is (filler tube, grommet for pump, crack in bottle itself, etc).
