Keystone TO3014116 Engine Coolant Reservoir Overflow Tank with Cap Replacement - OEM 164700F010

The Keystone TO3014116 is a direct-fit OEM-replacement engine coolant reservoir — also known as a coolant overflow bottle or expansion tank — designed to restore proper cooling system function. Partslink TO3014116 directly replaces Toyota OE part number 164700F010 and is engineered for the Toyota Sequoia V8 (Crew Cab) and Toyota Tundra V8 (Double Cab) applications.

The coolant reservoir captures antifreeze as it thermally expands from the radiator and returns it to the cooling circuit as the engine cools, maintaining the correct fluid level and preventing air ingestion. A cracked, leaking, or damaged reservoir can result in coolant loss and engine overheating — making timely replacement essential to protect the engine.

Key Features:

• OEM-equivalent fit and finish in white textured plastic to match factory appearance
• Includes reservoir cap for a complete, ready-to-install replacement
• Mounts to factory bracket tabs and hose fittings with no drilling or modification required
• Constructed to resist UV fade, vibration, moisture, and heat cycles
• Replaces OE part number 164700F010 (also cataloged as 16470-0F010)
• Partslink number: TO3014116

This reservoir is a drop-in replacement that installs at the factory location using the original mounting points, making it an efficient solution for collision repair or cooling system restoration on applicable Toyota trucks and SUVs.
