Motorad HD Radiator Cap

Heavy-duty cooling systems don’t forgive minor pressure issues. The Motorad HD Radiator Cap offers the necessary pressure control for maintaining coolant system performance in trucks with high thermal loads. This cap is rated for higher PSI than typical passenger vehicle caps, which makes it appropriate for diesel engines under heavy load or prolonged idling. The internal spring valve responds consistently to pressure shifts while retaining a solid seal when the coolant is cold. Shop the Motorad 1006-15 today.
