The hoses into and out of the radiator should be regularly checked for
impacts, cracks or leaks that could reduce the cooling system. For co-

the water pump you can drain the coolant circuit of
the engine. Before remove the radiator cap.
It is important to wait until the engine is at ambient
temperature to drain the radiator, to avoid any danger
of burns or scald.
The temperature sensor measu-
re the temperature of the engi-
