Radiator Cap with 10 PSI Pressure Rating and Relief Valve for Agricultural Equipment SKU: QT61838

A failing radiator cap causes serious overheating problems—coolant boiling over during heavy work, vacuum damage when cooling down, and mysterious coolant loss without visible leaks. This 10 PSI pressure cap maintains optimal cooling system pressure while preventing engine overheating and coolant loss in demanding agricultural applications.

Why Proper Pressure Matters

• 10 PSI pressure rating increases coolant boiling point by approximately 20-30 degrees Fahrenheit, preventing vapor formation that kills cooling efficiency
• Two-way valve system regulates coolant flow to and from overflow reservoir for consistent system operation
• Safety pressure relief prevents dangerous over-pressurization of cooling system during extreme conditions
• Corrosion-resistant materials ensure long-lasting performance in harsh environments

This professional-grade cap prevents the hot spots and system damage that cost you time and money during critical farming seasons. Always allow engine to cool completely before removal or installation and inspect radiator neck for damage before installing new cap.
