Keystone CH3014108 OEM Replacement Coolant Reservoir Tank with Cap and Hose

The Keystone CH3014108 is an OEM-replacement coolant overflow reservoir tank designed as a direct-fit solution for the Dodge Neon equipped with the 2.4L engine. This coolant recovery tank, also known as a coolant expansion tank or overflow bottle, is an essential component of the engine cooling system.

How It Works:

As coolant heats up during engine operation, it expands and flows out of the radiator into the overflow reservoir. Once the engine cools down, the reservoir returns that coolant back to the radiator, maintaining proper fluid levels and preventing overheating. A cracked, leaking, or damaged reservoir can lead to coolant loss and eventual engine overheating.

Key Features:

• Direct OEM-style replacement — no modifications required for installation
• Constructed from high-quality polypropylene plastic engineered to withstand underhood heat and vibration
• Includes cap and hose for a complete, ready-to-install solution
• Matches original factory fit, form, and function
• Replaces OE part number 5278953AC
• Partslink number: CH3014108

This reservoir is sold individually and is ideal for collision repair or cooling system restoration where the original tank has been cracked, damaged, or is leaking.
