Washer fluid leak - ML55
Need help - couldn't see the source looking from the top and underneath. Do I need to remove the headlight assembly? I disconnected the motor for the headlamp washers and still the same thing. The fluid is leaking right in front of the left front tire - looses about 1/2 the coolant capacity in about 2 weeks. Thanks.
By the way, thanks for the link on the coolant leak - I ordered a set of upper and lower hoses (leak in lower hose). Truck has 73k miles on it now.

A word of caution...the ESP/ABS control unit is directly below the washer bottle...I would not recommend letting the bottle continue to leak onto it.
There are two different size washer bottles. The older (smaller) style is easy to remove, one 10mm, 2 electrical connectors, and 2 hoses. Then the washer bottle can be lifted out. All replacement bottles are the large type no matter what you had before. To install the larger replacemnt bottle the connections are all the same...but due to the size, it typically requires that you partially remove/dissasemble the fuse box that is right behind the bottle . I've seen people cram the new bottle in without removing the fuse box, but more often than not you will end up with two leaking bottles rather than one. MBZ Labor time is 1.5hrs to replace this washer bottle. Hope this helps.
P.s. some of the newer large bottles have a 3rd electrical connector for the fluid level sender, and a plastic tab that secures the bottle on the LF inner fender
