Keystone SU3014106 Engine Coolant Reservoir Overflow Tank with Cap Replacement - OE 45150XA00A

The Keystone SU3014106 is an OE-style replacement engine coolant reservoir designed as a direct-fit substitute for the original equipment part. This overflow tank with cap replaces Subaru OEM part number 45150XA00A and restores proper cooling system function to vehicles where the original reservoir has cracked, leaked, or become discolored from years of heat cycles and road exposure.

The coolant reservoir plays a critical role in your engine's cooling system. When hot coolant expands beyond the capacity of the radiator, the excess flows into the recovery tank for storage. As the engine cools, that coolant is drawn back into the radiator by vacuum — keeping the system properly filled and preventing overheating. A cracked or leaking reservoir can result in coolant loss and potential engine damage.

Key Features:

• Direct bolt-on installation — aligns with factory mounting points and hose fittings with no drilling or modification required
• Constructed of durable polypropylene plastic engineered to withstand engine bay heat, UV exposure, vibration, and moisture
• OE-style appearance with white textured finish that matches the factory color and profile
• Includes cap for a complete, ready-to-install replacement
• Replaces Subaru OEM part number 45150XA00A
• Cross-reference part number: SU3014106

This reservoir is purpose-built for the Subaru B9 Tribeca and Tribeca and is an ideal solution for both routine maintenance and collision repair applications requiring cooling system restoration.
