Dorman Coolant And Washer Fluid Reservoir Assembly

The Dorman Coolant and Washer Fluid Reservoir Assembly line includes replacement coolant overflow tanks, also called coolant expansion tanks or coolant recovery reservoirs. These tanks hold excess engine coolant as it expands and contracts with temperature changes. Some designs also combine a windshield washer fluid reservoir in the same assembly. Each one is a direct replacement for a cracked, leaking, or discolored original tank.

Key Features:

• Replaces the original reservoir to restore proper coolant recovery and system capacity
• Built from durable, heat-resistant plastic designed to withstand engine bay temperatures and pressure cycling
• Engineered to match the form, fit, and function of the original equipment tank
• Helps maintain correct coolant level and supports the cooling system's pressure regulation
• Many assemblies include related components such as the cap or sensor, depending on the part number
• Combination designs include a washer fluid section to keep windshield cleaning fluid available

Dorman is a well-known aftermarket supplier of replacement parts. Replacing an aging reservoir helps prevent coolant loss, which can lead to overheating and engine damage. Choose the specific part number that matches your application.
