Universal Radiator Cap with Pressure Seal for Farm Tractors and Equipment SKU: QT55016

A failing radiator cap is more trouble than it appears—coolant boils at lower temperatures, air enters the system, and you lose coolant without seeing obvious leaks. This universal pressure cap restores proper system sealing to keep your engine running at safe temperatures during demanding field work.

Key Benefits

• Maintains correct pressure to raise coolant boiling point and prevent overheating
• Spring-loaded valve releases excess pressure while preventing vacuum formation
• Metal construction resists corrosion and temperature cycling
• Universal fit works with standard radiator neck designs across major brands

Install only when the engine is completely cool to avoid burns from pressurized hot coolant. Clean the radiator neck sealing surface and ensure the cap seats fully—a loose cap defeats the whole system. If you need help determining the right pressure rating for your specific model, give us a call.
