Fans and Kits for Chevrolet Silverado 2500 HD
A radiator cooling fan is a critical component of any vehicle, and the Chevrolet Silverado 2500HD is no different. A cooling fan that fails to function can cause your truck’s engine to run at too high a temperature and overheat, which can cause it to shut down or suffer irreparable damage. With a wide selection of fans and kits you can find what you need for your Chevrolet Silverado 2500 HD.
What problems cause cooling fans to fail?- Damaged fan blades cause reduced air flow when the fan runs.
- A faulty thermostat will fail to turn the fan on and off at the preset temperatures.
- A broken fan clutch can prevent the fan from turning at the right speed.
- A blown fuse or broken wires will prevent power from reaching the cooling fan.
- Electrical connections that are loose or corroded can cause intermittent failures.
- Your Chevrolet Silverado 2500HD’s temperature gauge rises higher than normal at times or begins overheating occasionally.
- The check engine light comes on.
- The air conditioning starts to lose its effectiveness.
- Start your Silverado 2500HD and let it run until it reaches its normal operating temperature. The cooling fan should begin running in the vehicle.
- Use a voltmeter to measure the voltage between the fan’s power supply and ground.
- If there are 12 volts present, the fan is getting power correctly. The problem is not the wiring.
- If there are zero volts present, the fan is not getting power. The problem may be a wire or the fuse.
- If there are more than zero but less than 12 volts present, the fan is only getting partial power. Check or find replacement for the wiring between the cooling fan and the battery until the problem is solved in your vehicle.
When checking the fan clutch inspect the fan itself for any obvious damage. If the fan isnt damaged, then follow these steps to check the fan clutch.
- Turn on your Silverado and let it run until it reaches a normal temperature. Check to see if the fan is running.
- If the fan is running, check that it’s running faster than the engine.
- If the fan isn’t running faster, there may be a problem with the fan clutch’s engagement.
Turn off your Silverado 2500HD’s engine and disconnect the battery cables to avoid the possibility of electric shock. Take care to ensure that the power hook-up is not reversed, or the fan may run in the reverse direction than intended. Don’t alter the fan assembly. For example, the housing and shroud are part of the cooling fan’s design. Removing them may cause the fan to perform differently than expected.
