Where is the thermostat located on a 2000 rover 25?

On a 2000 Rover 25, the thermostat is typically located in the engine coolant system, specifically at the engine end of the upper radiator hose. You'll need to remove the hose to access the thermostat housing, which is usually bolted to the engine block. Make sure to drain some coolant before attempting to replace it to avoid spills. Always consult the vehicle's manual for specific details and guidance.
