The most effective cooling system control ever developed. Provides faster engine warm-up, stable temperature control, longer thermostat and seal life, improved fuel economy and driver comfort. Vehicles can operate without radiator shutters, reducing front axle weight, cost and noise. Fleets can operate at higher temperatures without the unnecessary activation of shut-down devices or fan clutches.

• Machined bead edge that seats positively down on a resilient 3 piece flange. As a result, no-leak, precision control is even greater than the original Weir-Stat.
• Flange retains its elasticity, resists abrasion and corrosion, remains stable during extreme temperature and pressure changes.
• Packaging: Individually boxed.
