The comprehensive kit includes 4 heavy-duty German-made clamps for secure installation and comes with a Phillips screwdriver for your convenience. Perfect for creating a heater core bypass setup or managing coolant flow in multiple directions, this valve gives you precise control over your vehicle's heating system. The 5/8-inch size is compatible with many standard automotive applications, making it a versatile choice for various vehicle models. The robust design and quality materials help prevent leaks and ensure long-lasting performance under typical engine operating conditions.

【Dual Leakproof Design】This 4-way heater control valve is engineered for maximum leak prevention. The system combines a single, solid brass valve body (eliminating internal leak points) with heavy-duty, screw-tightened German clamps that enable precise, vibration-resistant sealing at every hose connection.
【Clear Seasons Marking】Know your mode at a glance. The knob features bold “SUMMER” and “WINTER” markings. Turn to Summer to boost A/C cooling; switch to Winter for maximum heater output. Ensures correct, worry-free switching every time.
【Single-Knob Dual-Mode】The precision engineering of this bypass valve delivers optimal climate control with a single twist. Forged from military-grade brass, the valve diverts coolant in Summer mode to boost A/C efficiency, and redirects flow in Winter mode for faster cabin heating.
【Withstands Extreme Heat & Pressure】 Engineered to perform in harsh engine bay conditions (-20°F to 305°F, 232 PSI). This durability comes from its CNC-machined solid brass construction, which resists corrosion, deformation, and ensures long-term reliability.
【Quick-Connect Installation】Simply insert the hose and tighten the clamp—always ensure the cooling system is fully depressurized and cooled before installation. Secure connections with hose clamps to prevent leaks (included clamps must be properly torqued).
【Package Contents】1 x 4-way heater core bypass valve, 4 x Heavy-duty German-style hose clamps (for automotive high-pressure connections), 1 x Phillips screwdriver (Note: Universal clamps fit both 5/8" and 3/4" valves).
