Radiator Cap with Spring Valve Pressure Relief for Tractor Cooling Systems SKU: QT58428

A faulty radiator cap causes serious cooling system problems—coolant loss, air pockets that create hot spots, and the engine overheating that destroys expensive internal components. This pressure cap maintains the precise system pressure your cooling system needs to prevent coolant boil-over and keep operating temperatures stable.

Why This Cap Matters

• Spring-loaded valve releases excess pressure at the correct point, preventing system damage
• Durable metal construction resists corrosion and thermal stress from repeated heat cycles
• Proper seal prevents coolant loss and blocks air infiltration that causes overheating
• Standard design fits most radiator necks without modification

When your cap is cracked, losing pressure, or the seal has deteriorated, this replacement restores cooling system function. S&H Parts has been solving cooling problems for farm equipment since 1969—call us if you need help confirming fit for your specific application.
