KNOW YOUR BUMPERS & FASCIAS

Bumpers and fascias have come a long way as vehicle designs, safety and Advanced Driver Assistance Systems (ADAS) have advanced. Many now include sensors, cameras, and other built-in technology that may need special care or professional calibration.

 

Here’s a quick look at how bumpers and fascias have changed on the Chevrolet Silverado 1500 and why some repairs might call for professional help.

HELP ENSURE SAFETY BEFORE HITTING THE ROAD 

Even minor body damage or glass replacement may result in damage to one or more safety-related systems on a vehicle. If you haven’t replaced sensors or other related Advanced Driver Assistance System components, a test for diagnostic trouble codes is recommended. 

If sensors or safety-related equipment have been replaced, calibration for them is required for optimal safety and performance. Have it performed at a GM Collision Repair Network shop.

BUMPER & FASCIA REPAIR GUIDE

Tackling the repair yourself? The procedures vary by model, but here are the basic steps in removing and replacing a bumper or fascia on your GM vehicle.  

1 of 6

REMOVE TRIM AND COVERS 

Remove necessary trim or covers on the bumper/fascia, including fender liners that may be attached on the back or sides and/or a radiator shield under the hood that may be attached to the fascia. Use a trim removal tool (also known as a fork) to prevent damaging plastic fasteners.

2 of 6

DISCONNECT ELECTRICAL 

Unplug fog lights, parking sensors, trailer plug wiring, radar modules, etc., as applicable. Secure harnesses out of the way, so they will not be pulled when the bumper/fascia is removed. 

3 of 6

REMOVE BOLTS AND BRACKETS 

Remove the bolts and/or brackets connecting the bumper or fascia to the vehicle’s body. There are often fasteners hidden from obvious view. Generally, sockets from 10mm-18mm are required.  

4 of 6

REMOVE AND REPLACE 

Pull the bumper or fascia straight away from the body. Fascias are also typically secured with additional snap fasteners or clips. A second person may be helpful to remove heavier truck bumpers. Installation of the replacement component is the reverse of removal.  

5 of 6

REASSEMBLE AND TEST FIT 

Transfer sensors, brackets, fog lights, etc., to the new bumper or fascia and bolt it on the vehicle. Reconnect electrical harnesses and reinstall the covers and shields. Check the function of fog lamps or other lighting that may have been removed and reinstalled.

6 of 6 

SCAN OR CALIBRATE

In a vehicle with integrated advanced safety technologies, visit a GM Collision Repair Facility for:  

  • Diagnostic scanning of the lighting and advanced safety systems 
  • Calibration of sensors such as parking, trailer, blind spot, radar and more. 
  •  Confirmation of system readiness and recording of calibration logs for warranty coverage.

THE IMPORTANCE OF GM GENUINE PARTS

It might be tempting to select less expensive aftermarket components, but GM original equipment (OE) parts are the only ones designed, engineered, tested and backed by General Motors.  
 
That’s important, because they are built to work with your GM vehicle’s safety systems and help restore the vehicle as close as possible to its pre-collision condition, which helps contribute to performance, safety, vehicle longevity and even resale value.

BUMPER & FASCIA REPLACEMENT FAQ 

Before tackling a collision repair yourself, be clear about the parts you’re using and the effects the repair may have on the vehicle’s safety systems. We’ve compiled a quick list below of the most common questions answers about DIY repairs. 

Do I need special tools?

Generally, no. Most bumpers and fascias can be removed with standard tools. Sockets and extensions are the most common tools required (typically 10mm–18mm), although some fasteners require a Torx® tool for removal. Some trim parts held in place with plastic fasteners are easier to remove with a fork tool.  

Do GM bumpers come with all the necessary trim and electrical?

It depends. GM Original Equipment bumper assemblies include the trim, electrical and harness, for simpler “plug and play” installation. GM OE partial bumper assemblies include the trim, but not the electrical or harness. They are more cost-effective alternatives if the vehicle’s existing electrical and harness components can be reused.  

Is painting required for the bumpers and fascias?

Yes. Apart from steel bumpers offered with a chrome finish, other bumpers and fascias are delivered primed and ready to paint.  

Are fasteners and bolts included with new bumpers/fascias?

No. If the vehicle’s original bolts, brackets, clips and other fasteners are no reusable for the repair, they are available separately from GM. See the Body Hardware section for more details.  

Is calibration necessary after replacing a bumper or fascia?

Yes. Vehicles with advanced safety features incorporating cameras, radar and other technologies must have professionally conducted post-repair system scans and/or calibrations to ensure the safety systems operate properly.
