Review MOPAR Plymouth Dodge Manifold Heat Thermostat Control Weight Nos fits 1934–1938

Introducing the Mopar 631055 Manifold Heat Thermostat Control for 1934-1938 Plymouth and Dodge vehicles, a vital component of your engine's heating system. This thermostat control is specifically engineered for these classic makes and models, ensuring a perfect fit and superior performance.

The Mopar 631055 is a crucial part of your vehicle's cooling system, responsible for regulating the temperature of the engine coolant that passes through the manifold heaters. By controlling the flow of coolant to the heaters, this thermostat helps maintain the optimal engine temperature for smooth operation and efficient performance.

This thermostat control is manufactured to Mopar's exacting standards, ensuring the highest quality and durability. It is engineered from premium materials, designed to withstand the rigors of classic automotive use. The housing is made from a strong, corrosion-resistant material, while the internal components are crafted from heat-resistant materials to ensure excellent performance even in extreme temperatures.

The Mopar 631055 features a simple yet effective design, with a spring-loaded valve that opens and closes to control coolant flow based on engine temperature. The valve is actuated by a temperature-sensitive wax element, which melts and expands as the engine warms up, allowing coolant to flow to the manifold heaters. As the engine cools down, the wax element solidifies, closing the valve and preventing coolant from flowing to the heaters.

Installing the Mopar 631055 Manifold Heat Thermostat Control is a straightforward process. It is designed to replace the original part on your 1934-1938 Plymouth or Dodge, making it an ideal upgrade for vehicles with aging or worn-out thermostat controls.
