Dayco Radiator Overflow Expansion Tank DOT0026

PRODUCT OVERVIEW

The Dayco DOT0026 radiator overflow tank is an OE-spec expansion tank designed to maintain correct coolant levels and support efficient cooling system operation in modern vehicles.

FUNCTION

This expansion tank collects coolant that escapes past the radiator pressure cap as system pressure and temperature rise. As the engine cools and pressure drops, the stored coolant is siphoned back into the radiator, helping to maintain proper coolant volume and reduce the risk of overheating.

• Durable construction to replace discoloured, brittle or cracked original tanks.
