I cleaned and flushed my washer system today (major improvement!)and I wish to question some logic here.

Why, on the windshield washer reservoir (the main one) is there the smaller tank? It's only connected thru the small hose at the bottom.

It gives you more capacity.

its for the headlight washers.

So says the manual also, but it only feeds into the main tank and both pumps take from that one.

Anyhow, I was just curious. Lol

The headlight washers create a requirement for additional capacity.
