Come to Auto Experts Medway in Chatham Medway for an engine management diagnosis and repair. We are Medway’s leading local garage close to Chatham Town centre that can diagnose and repair these types of engine management and coolant faults.

Radiator fan switch:

The radiator fan switch is automatically switched on when the coolant reaches a set temperature and this operates the cooling fan motor.

Coolant thermistor:

In modern cooling systems the fan control switch is replaced by a coolant temperature sensor. This is a thermistor which has a variable resistance, as the coolant heats up the resistance is reduced increasing the current flow to the ECU and the dashboard temperature gauge. The advantage of a thermistor is that it is very accurate in detecting changes in temperature and it is not simply a switch. In the case of this system the ECU will turn the radiator fan on or off according to the current flowing through the thermistor.

Health and Safety:

The engine should be allowed to completely cool down before one attempts to inspect or replace leaking or faulty coolant components. Exposure to the extremely hot coolant will cause serious bodily injury. Radiator coolant should be handled with care whilst renewing, because it is extremely poisonous.

Contact us and we can carry out a check of any cooling system components that are damaged and need to be replaced. Our workshop in Chatham is in the centre of Medway and is fully equipped to deal EML faults on many makes of vehicles that are on the road today.
