This complete cylinder head venting kit is designed to route trapped air and steam from the cylinder heads directly to the radiator or expansion tank, improving cooling system efficiency and temperature stability in high-performance applications.

The system vents from the center of each cylinder head and directs flow to the radiator at the cap or another preferred vent location. Installation requires drilling and tapping the radiator for two 1/8" NPT fittings. If an expansion tank is used, it should be mounted at the highest point in the cooling system for proper operation.

This kit is ideal for off-road and racing applications where consistent cooling and pressure control are critical.

Kit Includes:

• 6 feet of black -4AN hose

• -4AN straight hose ends (Qty: 12)

• -4AN T-fittings (Qty: 2)

• Water block adapters with mounting hardware (Qty: 4)
