Washer bottles built to hold fluid, not to weep it onto the fender liner.
The washer reservoir is a fatigue-tested plastic tank with pumps and level sensors embedded in it. Cracks and pump seal failures both mean the whole unit gets replaced.

Reservoir coverage
We stock washer bottles by capacity, pump quantity, and sensor provision. Rear-wash vehicles, heated washer nozzles, and headlight washer systems all affect the SKU.
When to replace a reservoir
Slow leaks and low-fluid warnings
Cracks in the bottle body cost your customer a fluid refill every week.
Front-end collision damage
The reservoir often sits ahead of the wheel and takes impact energy.
Pump failure with damaged pump port
A pump replacement isn't possible when the mounting port itself is worn.
Reservoir failure symptoms
Watch for:
- Fluid stains on the fender liner or engine bay panel
- Cracked bottle body visible under the reservoir
- Failed pump that won't seal against the mount port
- Level sensor throwing a fault when the tank is full
Why washer bottles come off
- 1Cracked bottle from freeze damage
- 2Impact damage from collision or debris
- 3Failed level sensor
- 4Pump port worn beyond re-sealing
Reservoir materials
Blow-molded polyethylene
The standard material — chemically inert to washer fluid.
Rubber pump grommets
Sealed grommets for pump mounting.
Integrated level sensor
Float or capacitive sensor for low-fluid warning.
Ordering a reservoir cleanly
Order pumps and grommets together
The reservoir arrives without pumps in most cases. Order both to avoid a second trip.
Confirm sensor connector
Level sensor connectors have changed generation to generation.
Inspect fill neck geometry
Some engines use a remote fill neck. Match the correct tube.
Washer bottle FAQs
- Do washer bottles ship with pumps installed?
- Not typically. Pumps ship as separate SKUs to allow single-pump or dual-pump configurations.
- Are your reservoirs freeze-resistant?
- The bottle material tolerates typical freeze cycles when filled with winter-rated washer fluid.
- Can you supply washer bottles with headlight-wash systems?
- Yes — for vehicles that came equipped, we stock the correct extended-capacity reservoir.
