Valeo Thermostats Cooling & Air Management  for Passenger car


What does a thermostat do?

The primary role of a thermostat is to maintain an engine’s minimum operating temperature. The thermostat keeps the antifreeze and coolant mixture within the engine when it is started and then opens upon reaching a specified temperature. The coolant then flows through the radiator keeping the engine at the thermostat’s rated temperature.
