How to replace the windshield washer pump and sprayer on the Smart 450.

Model: Smart Smart 450 - Years 1998-2007
Part: Checks and maintenance

If, when you activate the windshield washer, the sprayer no longer sends enough water to clean the glass properly, and the spray does not reach halfway up the glass, it means there is a problem with the pump. The pump is located behind the windshield washer fluid reservoir and is press-fitted, so you just need to remove it firmly and it will come off without any issues. Of course, it depends on the car you are working on: if it is a Smart car, there will be very little space to work with. If the plastic does not hold well, you will need to wrap it with a few layers of heat shrink tubing, because if it doesn't hold, changing the pump would have been pointless: it still won't spray properly. When you change the pump, some fluid will come out of the reservoir: you need to collect and dispose of it at an authorized center, you cannot simply pour it down the sink. You can find the pump on Amazon for 13.48 euros, including delivery charges. We reinstall it by pushing it into its housing. Now we also clean the sprayers with a brass wire, inserting it deeply. Then we blow into it to check if air comes out or not. Job done.
