Having an issue with the spray on the rear of my W163 as shown:



I have replaced the water pump and that cover arm and it shoots the water back on itself - anyone have any fix to this issue?

water pumps nicely as when I remove the wiper cover arm, it sprays about 6-7' (2m) without issues. its like the angle is hittintg the cover wrong and I have tried to jiggle it about without any success.

Remove the cap/cover and look for blockage in the cap.

I bought a whole new cover/cap just in case and the photo showed with the new cap. The old was a bit broken but also did the same thing. Both does not have any blockages or anything that I think wold stop it from spraying correctly. I can post photo of both caps if needed.

I think I found the problem - its missing the nozzle which after looking at other cars to spray it outwards:



Anyone know that part number or what can be used to disperse water - or if there is a CAD design and maybe I can get my son to print for me?

Maj. Dundee

What is you vin#?

Maj. Dundee

Here is the part # for the spray nozzle but it comes as a kit only. Also replace the cap.

Sorry mate I didnt reply earlier, was out back yelling at the lawns!

That's exactly the part I needed - https://www.ebay.com.au/itm/For-Merc...-/350709863351

I dont have an arm puller device thingy - Im hoping I can pull the bolt and washer (26/29) to get to the top part and only replace that and possibly that rubber #8.

Maj. Dundee

Use this.
