How Do You Replace A Chevy Colorado ABS Sensor?
Before anything else, ensure that your workspace is secure and devoid of safety hazards. Always follow safety measures like:
- Never smoke or bring flammable objects while working with your Chevy Colorado.
- Ensure that the vehicle doesn’t move by engaging the parking brake and placing wheel chocks when necessary.
- Ensure that the engine is cool before lifting the hood and touching the vehicle’s different parts.
- Always use equipment, materials, and tools that don't have damage.
- If you’re going to work with harsh chemicals, wear protective gear like safety gloves and goggles.
After making the necessary preparations, follow these steps to replace the ABS sensor of your Chevy Colorado:
What You’ll Need
- Socket wrench
- Car jack
- Jack stands
- Wheel chocks
- Penetrating automotive lubricant
Step #1: Disconnect The Battery
Disconnecting the battery ensures that the Chevy Colorado won’t have power, reducing the risks of accidents while replacing the ABS.
Start this step by removing the negative wire from the battery’s negative terminal with the socket wrench. Once removed, place the negative wire on a non-metal surface so it doesn't create a charge.
You may also remove the positive wire from the battery’s terminal. Although it’s not a requirement, you may proceed by taking out the battery from its mount to ensure that power won’t flow from it.
Step #2: Raise The Chevy Colorado
Use the car jack to raise the Chevy Colorado. If you’re having difficulty finding the included jack in your vehicle, check the space underneath the passenger seat. Otherwise, you may need to purchase a jack from a reliable retailer before you can move forward with this process.
Once raised, place jack stands underneath the Colorado’s chassis for extra support. Then, place wheel chocks on the grounded wheels to prevent the pickup truck from rolling.
Step #3: Remove The Wheel Assembly
With the socket wrench, loosen the lug nuts on the wheel assembly. Make sure to loosen the nuts using a star pattern to prevent the wheel from falling, which would otherwise put you at risk of injury.
Once the lug nuts are loose, pull the wheel assembly out of its mount and set it aside temporarily. If you think that the wheel is too heavy for you, call someone to help you with the lifting and carrying. If done correctly, you should now be able to access the Colorado’s ABS.
Step #4: Lubricate The Brake Assembly
Make this procedure easier for you than expected by lubricating the brake assembly, particularly its fasteners. Use your penetrating lubricant on the brake’s bolts. Allow the solution to set for about 20 minutes afterward.
Step #5: Loosen The Rotor’s Bolts
Take note that the brake assembly will spin as you’re loosening the bolts. Prevent that from happening by wedging a screwdriver in the brake rotor. Then, use the right-sized socket wrench to loosen the bolts.
Step #6: Remove The Caliper
Remove the wedged screwdriver. Then, unscrew the bolts from the brake caliper. Take note that there are two bolts for this particular assembly. One of the bolts is at the top of the caliper and the other is at the bottom. Carefully pull out the caliper afterward.
Step #7: Remove The Rest Of The Brake Assembly
Turn the wheel of your Chevy Colorado to the left. That way, you can gain access to the bolts securing the rest of the brake assembly. Remove these fasteners with the right-sized socket wrench. Next, pull out the brake assembly and set it aside temporarily.
Step #8: Take Out The Old ABS Sensor Cable
Loosen all the ABS sensor cable’s connection points. Next, apply sufficient pressure to the sensor cable’s fastener (located at its end) to push it out of its mount. Disconnect the old ABS sensor cable and remove it from the Chevy Colorado afterward.
Step #9: Install The New ABS Sensor Cable
Route the new ABS sensor cable in the Chevy Colorado. Ensure that the cable has ample moving room so that it won’t get stuck when the pickup truck moves. Then, connect the wires to the new ABS sensor cable and secure it in place with its fasteners.
Step #10: Return The Parts And Test The New ABS Sensor
Ensure that the new ABS sensor cable is secure before returning the assemblies and parts you removed from the previous steps. Once you’re sure, reinstall the brake system and the wheel assembly.
Then, remove the jack stands and the wheel chocks. Lower the vehicle to the ground and test the new ABS sensor to check if the problem persists. If the issue is still present, it might be time to send your Chevy Colorado to skilled automotive technicians.
