Windscreen / windshield washer pump / motor replacement

My 2001 SLK230 washers stopped spraying last week. I checked the fuse and decided the pump had probably busted. There was no noise from it. This happened previously two years ago when I test drove it and the dealer said they had to replace it. I'm surprised they fail so easily.

The good news is that the pump is quite cheap (about Ł6 on eBay) and it isn't too difficult to replace. The washer tank is on the leftside of the car looking from the front.

Sorry no photos but here's how you do it:
You need to remove the wheel and undo five 13mm nuts/bolts to drop the wheel arch trim down to get to the tank. There are another couple of nuts holding the trim underneath the car but the trim will pull down far enough.

The white tank is held with a single 13mm bolt to the bodywork. The bottom on the tank has a rubber grommet that sort of slots into a metal retainer. You need to detach the black filler pipe from the top first. I undid the nut holding it in the engine compartment and then spent 20mins trying to prise it from the black concertina pipe that goes into the tank. I suggest you pull the black concertina pipe out of the tank. It is just a push fit but may require a good pull.

The tank will be heavy if full of water. Firmly wiggle and pull it forwards. There are pipes attached. You do not need to completely remove the tank from the car. Drain the tank either by tipping forward into a jug or there is a rubber plug that may also do the same thing near the bottom.

The pump motor will be on the side of the tank facing you. There is a pipe connected to it that is pressed into a recess on the side of the tank. You can undo the screw clip and pull the pipe off the pump. Pull the pump motor up and out of the rubber seal in the tank. Detach the electrical plug.

Just replace the pump and refit the pipe and tank. Make sure it works. There is a couple of pipes going through a cap in the top of the tank. I think these are carrying hot water or air from the engine to heat the tank in winter. Make sure this cap is clicked onto the top of the tank. Mine was loose and I think it was this causing it to leak when filled - not the just gap between the filler pipe and concertina pipe like many people think.

Hope this helps.

Question "Detach the electrical plug."

Hello Folks, this is just what I need, but how do you detach the electrical plug. Mine won't budge. Is there the usual secret MB locking mechanism that I have not sussed out, or do I just need to pull harder? Thanks, psyber

My SLK R170 isn't spraying fluid also.
Have to check what's wrong with it later this week. Does anyone have a link where I can buy a cheap pump as mentioned in the first post from ebay?
Thanks for the help already.

Cool Pump

Hello Ridsel, the pump is not expensive from Merc themselves, even compared with Amazon/ebay. It's just a bit of a chore to replace the unit. Did mine, no probs.

But you have to take of the wheel and the shield to get to the pump?

Just a note for everyone that has the front light washer system-if you plan on replacing your headlights DO NOT waste the money to get the pump fixed.

*guess what I did? yep that's right. I wasted $ to get a new pump put in and less than 6 months later I changed the headlights to spyders.

Yes. It's a real pain. Go here for a perfect description of what to do. Pelican Technical Article - Mercedes SLK 230 - Windshield Reservoir Replacement
It took ages. Order up the appropriate replacement seal before you start.
Good luck.

Thanks to Simon, his review was great.
The steel pipes through the top are full of coolant, the flow is used to warm the fluid. So dont do it just after a long run, they are warm!!

There is a collar that links the neck to the flexible pipe, this needs to be slid downward (twisting helped) and the neck comes out easily.

I couldnt get a pump locally so I pulled the top off, the motor pulls out. I gave it a good soaking in wd40 freed the shaft, ran it off a battery until it ran smoothly again and reassembled. It was very messy and rusty but cleaned the worst off, put some grease in the base before putting together. I assume water enters it slowly while in use.

Thx for this DIY. Replaced the pump....still didn't fix the low flow on the drivers side. I just replaced BOTH spray nozzles 6 months ago so something has happened to the drivers side one or something got into it. I tried blowing compressed air through it...made it better but it is still higher resistance. Did fix the T-connector minor leaks tho'...so there's that!

Thanks for that link to Pelican. That really helped me as I thought I purchased the wrong pump. I was looking at the headlight washer pump and didn't know I needed to remove the reservoir.

Unhappy Done and done...almost

Thanks to advice on this thread, I have finally replaced the windshield washer pump. The passenger side sprays fine, but the driver side barely dribbles out. I took a small pin and poked in the nozzles, but there must be some other obstruction. Any advice is welcome. Thanks.
