Windscreen washer pump
Having fitted the twin windscreen washer mod to my defender the pressure of the water coming out has dropped Big Cry this could be down to it being an old motor and replacement could solve the problem but I wondered if anyone knew if the rear screen washer pump was more powerfull as it has to pump the water further? It has a different part number to the front so if it's stronger I may just fit two of them. Alternatively does anyone know of a better pump that's an easy fit?

Cheers
Ray

Have you check that the non return value is working correctly? Mine didn't allow more than a dribble through. Fixed by drilling it out so no longer a value Smile

Passenger side - engine bay near the bulkhead.

It looks like it's just joining the two pipes together.

Big Cry not the valve on mine. I've been reading round the net and a few mentions of disco 2 headlight washer pumps have come up but no confirmation they work so I've ordered one to give it a go.

I'm sure there was a thread on here a while ago about this and I'm pretty sure that the rear washer pump is more powerful than the the front one (they have different part numbers). 2005 Td5 90 XS

I did a search on here but didn't find that one. I tryed swapping them over today and it didn't make much difference aswell as getting rid of the nrv which did nothing so I'm going to try a headlight washer pump when it arrives.

When it arrives, you'll find that the D2 headlamp washer pump uses a larger sealed connector than the Defender's windscreen washer pump.

If the D2 pump physically fits your washer bottle, I can help with the connector required for the D2 pump, or a short adaptor harness from the Defender's harness to the D2 pump.

The D2's headlamp washer pump connector is the same as used on each half of the D2's heated windscreen -

The connector to mate with the Defender's washer pump connector, is this -

If the D2 pump fits the Defender's washer bottle, and delivers the volume/pressure you want - then, the only issue that I can see is that the Defender's wiring isn't heavy enough to supply the D2 pump.

On the Puma, the front washer pump wiring is in 0.5mm˛ cable.

On the D2, the headlamp washer pump is wired in 1.5mm˛ cable, and fused at 20A.


The proper way to wire it would be to have the Defender wiring switch a relay powered from its own 20A fuse, which switches the D2 pump on heavy gauge wiring.
