Radiator cap for Terex PT70

The radiator cap 0201-884 serves as a pressure-regulating component within the cooling system of the Terex PT70 compact track loader. It is installed on the radiator and oil cooler assembly to manage internal system pressure and prevent coolant loss during engine operation. By maintaining a specific pressure rating of 13 PSI, the cap effectively raises the boiling point of the coolant, which allows the engine to function within its thermal limits. This component also includes a vacuum relief valve that facilitates air intake as the engine cools, preventing the collapse of cooling system hoses.

This part is compatible with the Terex PT70 model. It functions as a safety valve, releasing excess pressure if the system exceeds the 13 PSI threshold to protect the radiator and associated cooling components from structural damage. Radiator caps are designed to ensure that the cooling system remains sealed under standard operating conditions while providing a necessary release mechanism to prevent over-pressurization. Regular inspection of the cap ensures that the seal remains intact and the pressure relief mechanism functions as intended to support consistent engine thermal management.
