Product Details

The Dorman Dual Coolant / Windshield Washer Fluid Reservoir line offers direct-replacement combination tanks. Each one holds engine coolant (recovery) and windshield washer fluid in a single unit. It is also sold as a coolant overflow tank, coolant recovery bottle, or washer fluid tank. It replaces a cracked, leaking, or brittle factory reservoir.

Key Features:

  • OE-style replacement: Engineered to match the fit and function of the original part for a straightforward installation.
  • Durable plastic construction: Made to withstand underhood heat, stress, and engine vibration, which can crack and leak aging factory plastic.
  • Tested for reliability: Designs are tested to help ensure dependable performance in demanding conditions.
  • Convenient components: Models typically come with a reservoir cap. Some include a level sensor or mounting bracket where the original design used one.

Dorman is a long-established supplier of aftermarket replacement parts. These reservoirs give you an affordable, reliable alternative to a dealer-sourced part and help restore proper coolant and washer fluid storage.

Fast checkout

I don't know why o padi for 2xday delivery, should've did regular shipping.

This is only my 2nd purchase with autoplicity. My first order was timely. The product seems to be great so, I'm ordering a 2nd one.

Hey, I ordered an aqua hot yearly maintenance kit. It was a pretty smooth transition and kit arrived shortly afterwards. Everything was in the kit as described. Definitely would order from Autoplicity again! CJ3
