Radiator Cap with Pressure Relief Valve for Agricultural Tractors and Equipment SKU: QT59394

A faulty expansion tank cap leads to coolant loss, air in the system, and eventual overheating problems. This universal radiator cap with pressure relief valve maintains proper cooling system pressure while preventing contamination and coolant loss that can leave you stranded during critical field operations.

Why This Cap Matters

• The pressure relief spring is calibrated to open at the correct pressure, preventing system damage while maintaining efficient cooling
• The vacuum relief valve allows coolant to flow back from the expansion tank as your engine cools, preventing air pockets that cause hot spots
• Robust gasket material creates a reliable seal that won't deteriorate from coolant exposure or compress over time
• This universal cap works with various tractor brands using standard expansion tank designs

When your cooling system runs at proper pressure with a reliable cap, your engine stays protected through long days of heavy work. Questions about fitment? Call our team - we've been matching the right parts to farm equipment since 1969.
