screen wash reservoir.......

[Mr Roper]

Thinking out loud here but why don't modern cars have the ability to use rain water to top up the reservoirs?

I know it's not the end of the world not to have it but like i said I'm just thinking out loud....

Probably a number of reasons, but the main one being that they'll get clogged up with leaves and crap, even with a filter in place at the top of the inlet.

You'd have to feed it from somewhere, probably the cowl top in front of the windscreen, if you've ever seen the state of the water and debris that sits in there you'd understand why you don't want it to flow throught your wash pump!

Also, the tubing would somehow have to be routed along the bulkhead to the wash tank and that would be a pain in the arse!

Or heated to stop them freezing? I have heated jets but that doesn't help when the tank is frozen!

Mum had an Austin 1300, which would let you disconnect the washer bottle & bring it indoors.

You wouldn't need screen wash water in the rain.
