Stant 45119 Engine Coolant Thermostat

Overview

Stant Superstat Thermostat 45119 is a 195-degree engine coolant thermostat built for direct replacement applications across a wide range of trucks, vans, SUVs, and passenger cars. It is listed for Chevrolet Silverado 1500, GMC Sierra 1500, and Volvo C30 applications, with fitment coverage extending across multiple model years.

The Superstat line focuses on cooling-system control under demanding operating conditions. This thermostat uses a high-venturi design for strong coolant flow, a larger piston for increased opening force, and a stainless steel flange with a burnished finish for added corrosion resistance.

• 195-degree thermostat calibration for OE-style temperature control
• High-venturi design for increased cooling capacity under load
• Larger piston diameter for stronger actuation
• Stainless steel flange with burnished finish for corrosion resistance
• Thicker flange construction for added rigidity
