Why is my electric cooling fan not working?
Or the silicone grease can leak causing the fan to “freewheel” while failing to pull air through the radiator. Step 2 – An electric cooling fan is used primarily to boost engine performance and cut down on emissions. These fans are featured in both front and rear wheel drive vehicles and are activated by a coolant sensor via the computer.
What happens if your car cooling fan is too low?
If the motor that drives the fan is faulty, then a new motor will have to be fitted. Check the engine coolant level. If your engine coolant’s too low, it means that the cooling fan will have to work harder to keep the engine at a normal temperature.
What should I do if my radiator fan stops working?
Turn the air conditioning to the maximum setting – this should spark the cooling fan to immediately come on. In older cars, this typically takes about 15-20 minutes for the engine to reach the right temperature. If there’s a problem with the engine’s temperature, then this can damage the radiator.
What happens to coolant when clutch fan fails?
When cooling fan operation fails it will cause engine coolant to retain heat, forcing the engine to run hot and eventually overheat. The first clutch fan was developed in the late 1960’s and was in full production by the early 1970’s. This clutch fan was designed to save energy and lower emissions.
When to troubleshoot an electric car cooling fan?
On a warm engine, the fan may come on even if the engine is not running. When working on a hot engine or an engine that is running, keep your hands and tools away from the fan blades and moving components. Troubleshooting a cooling fan that doesn’t work can be a relatively straightforward task at times.
What happens when an engine coolant fan fails?
All engines have a preferred operating temperature which require a warm up period to operate at peak efficiency. Temperatures above normal can cause internal engine parts to fail. When cooling fan operation fails it will cause engine coolant to retain heat, forcing the engine to run hot and eventually overheat.
What causes a cooling fan relay to stop working?
Cooling fan relays can stop working for any number of reasons. Common causes for relays going bad include: There are several ways to tell if a bad cooling fan relay is to blame for an overheated engine. The easiest method is to start the engine and then turn on the air conditioning.
What happens when a clutch fan does not work?
Temperatures above normal can cause internal engine parts to fail. When cooling fan operation fails it will cause engine coolant to retain heat, forcing the engine to run hot and eventually overheat. The first clutch fan was developed in the late 1960’s and was in full production by the early 1970’s.
