Checking the Thermostat (Scorpio 2)

Slowly heat the thermostat in a bath of water. The thermostat should not touch the walls of the bath and should be completely immersed in water. Monitor the water temperature with a suitable thermometer.



Once the water temperature reaches the opening temperature, the thermostat valve should begin to open.

Engine	Opening temperature,°C
4-cylinder petrol	from +85 to +89
V6	from +79 to +83
Diesel	from +69 to +72

Check whether the thermostat valve closes completely when it cools down, otherwise replace the thermostat.
