Get Rid of the Bearing Noise with New A/C Clutch Solenoid
Hearing a bearing noise after turning on your air condition may hint a problem with your A/C compressor clutch. Of course, there can be other culprits, so find time to check other components. Your vehicle's tensioner, water, and alternator pulleys should be on your list. If none of the parts are damaged or create noise, then it's time to check the A/C compressor pulley, which houses the clutch and coil. Should the pulley show no signs of wear, then the clutch and bearing should be replaced, especially when the A/C clutch solenoid is shot.
Things you'll need:
- Snap ring pliers
- Gear puller
- Pry bar
- Brake cleaner
- Penetrating oil
- New A/C compressor clutch coil
Step 1: Jack up the front side of your vehicle to access the A/C compressor. Make sure that you perform this replacement procedure in a safe location to avoid accidents during the process.
Step 2: Depending on your vehicle, you have the option to remove the A/C compressor from the engine bay if there is not enough room. Remove the mounting bolts using a wrench to take the compressor out, and disconnect all the wires from your A/C compressor.
Step 3: Remove the bolt that secures the clutch on the pulley. Use a screwdriver to keep the clutch in place and a ratchet to loosen the bolt.
Step 4: Use a snap ring pliers to remove the snap ring on the pulley.Take out the snap ring then remove the pulley using a gear puller.
Step 5: If you're having difficulty removing the pulley in the absence of a gear puller, spray some penetrating oil on the pulley and let the chemicals sit for about 15 minutes or depending on the instructions of the product you're using. Cleaning the pulley with brake cleaner is also advisable to help loosen the dirt that has accumulated on the pulley over time.
Step 6: In the event that the pulley still doesn't come off, you may use a pry bar. Place the pry bar under the pulley then pull on the bar while rotating the pulley to avoid binding.Take note that doing this step is should be treated with extra care.
Step 7: To remove the A/C clutch solenoid, remove the snap ring first. If the clutch coil get stuck, use the available tools that you have to pry it off.
Step 8: Test the measurement of your old coil using a voltmeter. If the measurement reads less than 3.4 ohms, then the solenoid has to be replaced.
Step 9: Before installing the new coil to your compressor, make sure that all the parts are in good condition. Also check of the replacement kit has all the components needed.
Step 10: Turn on the A/C once a new coil has been installed and all parts returned to your vehicle.
Replacing your A/C clutch solenoid may require longer time, especially when the pulley and the coil get stuck. Moreover, ensure that the place you're working on is away from the road.
