Dorman Non-Pressurized Coolant Reservoir Tank with Cap

The Dorman non-pressurized coolant reservoir tank with cap is a replacement coolant overflow tank, also called an expansion tank or coolant recovery bottle. It holds the excess coolant that escapes the cooling system as the engine heats up. It then returns that coolant as the engine cools, which helps keep the coolant level stable.

Key Features:

• Replaces a cracked, leaking, stained or warped reservoir
• Non-pressurized design for coolant overflow and recovery
• Includes a cap
• Molded from durable, heat-resistant plastic made for the under-hood environment
• Designed to match the form and function of the original part, so installation is straightforward
• Translucent construction on many versions, so you can check the coolant level at a glance

A damaged reservoir can cause coolant loss, low coolant levels and overheating. Replacing it restores proper coolant management and helps protect the engine. Dorman is a trusted aftermarket brand known for OE-style replacement parts and for solving common failure points.
