Universal Radiator Cap for Farm Equipment and Small Engine Applications SKU: QT42029

A worn radiator cap might not look like much, but it causes major problems. Without proper pressure, coolant boils at lower temperatures, leading to overheating and coolant loss. Overheating ruins more engines than almost anything else, and your radiator cap is the unsung hero of your cooling system. This universal replacement cap maintains proper cooling system pressure to prevent expensive engine damage.

Why This Cap Matters

• Proper pressure rating increases coolant boiling point by approximately 20-30 degrees Fahrenheit, preventing vapor formation that reduces cooling efficiency
• Precision-engineered two-way valve system regulates coolant flow to and from overflow reservoir
• Durable construction withstands extreme temperature cycling and vibration
• Safety pressure relief prevents dangerous over-pressurization of cooling system

This replacement cap features the correct pressure rating and robust construction to maintain your cooling system's efficiency year after year. Always install caps on cool engines to avoid burns from hot coolant. Check the radiator neck for damage or corrosion that could prevent proper sealing.
