How to remove and test a thermostat in a cooling system?

Drain the cooling system and remove the thermostat. Clean it and test in heated water. It should open at 84 'C for manual models, 50'C for automatic models, and close quickly in cold water. If it works, refit it, ensuring the clamp and arrow face the direction of travel. Clean the housing, refit the cover with a new gasket if needed, and tighten the bolts evenly. Refill and bleed the system.
