Description

High performance racing engines require upgraded and improved cooling systems for maximum reliability. One important component of the upgraded cooling system is a thermostat that opens to allow coolant passage through the engine and cooling system at reduced temperature compared to the original equipment thermostat. Reducing the temperature by approximately 10 to 15C compared with that of a standard thermostat, the Cosworth LowTemp Motorsport Thermostat improves coolant circulation through the engine by starting the process earlier than the original equipment thermostat.

Cosworth LowTemp Motorsport Thermostats are engineered with the optimum temperature range in mind for high performance racing use as it is very easy to over cool the engine by either removing the thermostat completely or using a thermostat that is not designed for the specific application. Additionally, over cooling can cause engine damage by preventing critical engine components from reaching their ideal operating temperature, altering the required clearances for safe operation. Another important feature of Cosworth LowTemp Thermostats compared to other brands is the ability to precisely control the flow of coolant when the valve opens. Inferior brands allow the coolant to surge thereby causing unstable temperatures and even temperature fluctuation that can cause severe engine damage and make it difficult to properly tune or calibrate the engine.

When combined with a correctly sized radiator and other high quality cooling system components, the Cosworth LowTemp Motorsport Thermostat will help to safely maximize engine performance by controlling the engine temperature at an optimum level .
