I have just cured the reoccurring problem with the windscreen washers on my 146 i.e.: motor/pump working fine but low water squirting pressure.
Not a big job, just a bit fiddly due to expansion tank being in the way of access to the black windscreen pump (white for headlamps)
With out disconnecting any hoses….
Remove the 3 fixing screws that secure the radiator expansion tank, and move out of way…towards engine as far as possible to give access to washer pump, and secure/wedge.
Remove the electrical conectors from both pumps, and move aside.
There are two small bore plastic pipes coming from either side of the bottom of the pump, they both have a connection/break in each pipe line found on the inner wing at side of the washer bottle.
Split the pipes here, use broad blade screw driver or similar to prise the pipes apart rather than trying to pull part, and be careful of your fingers and your paint work.
You are now going to lose all your washer bottle water so do not leave your tool box on the floor it will get wet.
Reach down in to the access you have made and pull out the black washer pump from the washer bottle, it is simply a push fit with a rubber bung/seal.
One of the pipes fits around the headlight washer pipe….and this is the fiddly bit…not too bad to pull out but hard to thread back around, so have a good look before you remove.
Lift clear/remove the pump from the car.
There is a small plastic filter on the bottom of the pump witch simply pulls off.
Mine was full of gunk, and was almost completely blocked up.
Clean the filter (with old tooth brush), and replace.
You may wish to check the pump before you refit, by reconnecting the electrics and placing pump in mug of water…mine was fine.
Refit all in reverse order.
Refill the washer bottle with water.
And now you may have to reangle the washer jets with the aid of a pin, as mine were squirting water way above the roof of the car, such was the improvement in the water pressure.
