The cooling system will maintain normal operating temperature under all driveable conditions.
THINGS TO LOOK FOR
It’s always a good idea to look at the thermostatic fan to understand how it operates. Because thermostatic fans are thermostatically controlled and they should switch on and off. A good thermostatic fan in a very good cooling system will switch on for somewhere between 20-40 seconds. If the fan switches on for longer than 60 seconds this might be a cooling system that is unable to cool down with the thermostatic fan. Another problem might be associated with the cooling system. If the fan stays on for 5 seconds, this is an excellent cooling system as it never requires a lot of effort from the thermo fan.
