Review S / WORLD AMERICAN S/ Vented Thermostat 170 855.s S# Ref.# Cat fits CUMMINS

The American S-43021 Vented Thermostat is a crucial component in the cooling system of Cummins 855 engines, specifically those with the 4L7615 855 reference number and Cat 4L7115 855 serial number. This thermostat is designed to maintain optimal engine temperature, ensuring efficient performance and extended engine life.

The S-43021 thermostat is a vented type, which means it utilizes an external vent to release excess pressure when the coolant reaches the desired temperature. This design helps prevent coolant system damage caused by overpressure. The vented thermostat housing is made of durable, corrosion-resistant materials, ensuring long-lasting performance even in harsh operating conditions.

The thermostat features a precision-machined stainless steel stem and a heat-sensitive wax element. The stem is designed to seal the coolant passage when the engine is cold, preventing coolant from flowing to the radiator. Once the coolant temperature reaches the desired level, the wax element expands, allowing the thermostat to open and release the coolant to the radiator for heat exchange.

This American S-43021 Vented Thermostat is a direct replacement for the original equipment thermostat in Cummins 855 engines. It comes with all necessary hardware for installation, making it a convenient and hassle-free upgrade or repair solution. The thermostat is also backed by a manufacturer's warranty, providing peace of mind and protection against defects.

In summary, the American S-43021 Vented Thermostat is a high-quality, durable component designed to maintain optimal engine temperature in Cummins 855 engines. Its vented design helps prevent coolant system damage caused by overpressure, while its precision-machined components ensure reliable performance. This thermostat is a direct replacement for the original equipment thermostat and comes with a manufacturer's warranty.

The American Standard S-43021 Vented Thermostat is a popular option for regulating the temperature in cooling systems using Cummins 855 engine models, specifically those with the Cat 4L715 855 reference number.
