Washer Bottle

[matt190580]

Hello all

Fairly new to this so bear with me!

Have had a problem over the last few weeks, wife had a slight knock in the ti and ever since the car seems to lose all washer fluid.
Ive taken the bottle apart and stripped it down cleaned plug and resealed the hoses but the other day i still managed to lose 15litres. As the weather is in decline i dont wanna get caught out with no fluid!

Ive looked again this morning and there is a hose that drops down behind the radiator does anyone know where this leads to? ive a feeling it may be split!
Also checked the lines leading to the bonnet and the rear washer, so am really stumped by this!
Any help would be great

Many Thanks in advance

You don't say which car you have, and I don't know if all washer systems are the same (M42 vs. M42, etc.).
You are dealing with a reservoir (plastic), a pump (plastic), level sensor (plastic), assorted grommets and an outlet hose (rubber or plastic). All are prone to deterioration over time.
Pull the bottle/pump/sensor and take them inside. Fill the bottle and see if it leaks - hairline cracks may be difficult to see, in any of these items.
Find known good used components or treat your car to a present and buy new!
