Radiator Pressure Cap for Agricultural Equipment with Spring-Loaded Relief Valve SKU: QT1874445

A worn-out 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. This replacement cap maintains the correct system pressure your cooling system needs to prevent boiling over during demanding field operations.

Why This Cap Matters

• Pressure cap raises your coolant's boiling point, letting it absorb more heat without turning to steam—increases boiling point by approximately 20-30 degrees Fahrenheit
• Correct pressure rating and robust construction to maintain your cooling system's efficiency year after year
• Spring-loaded valve automatically releases excess pressure to prevent system damage
• Quality seal prevents coolant loss and air infiltration under heat and vibration

Replace the pressure cap with the correct pressure rating. 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. A good cap can't seal on a damaged neck.
