Dayco HD Coolant Expansion Tank DET5002HD

Dayco HD Coolant Expansion Tank Fits Daf CF 75, CF 85

The Dayco HD Coolant Expansion Tank is a crucial component designed to maintain the efficiency of your vehicle's cooling system. It operates under pressure, with the pressure cap located on the tank itself rather than the radiator. This tank is typically positioned at the highest point in the cooling system, allowing for the continuous cycling of coolant. As the hot coolant expands, it fills the upper section of the tank, creating pressure that pushes coolant back into the system. Over time, expansion tanks can become discoloured, brittle, or contaminated, necessitating prompt replacement to ensure optimal performance.

Manufactured to original equipment (OE) specifications, the Dayco Expansion Tank is model-specific, making it suitable for a range of Australian vehicle models. For guaranteed compatibility, add your vehicle details to My Garage, which activates our 100% Fitment Guarantee.
