Working

The Motorad Expansion Tank Cap PCD000070 plays a crucial role in your vehicle’s cooling system. Installed on top of the coolant reservoir (expansion tank), it helps maintain the proper pressure by sealing the tank and allowing excess pressure to escape when it exceeds a specific threshold. This not only prevents coolant loss through evaporation or boiling but also ensures the engine operates at optimal temperature. The pressure relief valve built into the cap is calibrated for precision, ensuring that your radiator and hoses stay protected from overpressure damage.

Quality and Capability

Built with high-strength thermoplastics and corrosion-resistant internal components, the Motorad Expansion Tank Cap PCD000070 is rigorously tested for pressure retention, durability, and leak prevention. It performs reliably in extreme temperature fluctuations and under constant exposure to coolant and under-hood heat. While it is an aftermarket solution, Motorad’s adherence to international quality standards ensures long-term reliability and consistent cooling system performance. For drivers and technicians seeking a dependable replacement at an affordable price, this cap delivers trusted functionality without compromising safety or fitment.
