OEM repair methods explained

What does OEM mean?

OEM stands for Original Equipment Manufacturer—the company that made your vehicle (such as Toyota, Ford, BMW, or Volkswagen). OEM repair methods are the procedures and specifications developed by these manufacturers for repairing their vehicles.

What OEM repair methods cover

Manufacturers publish detailed repair procedures that specify:

• Which parts can be repaired vs replaced: Some components must be replaced entirely for safety reasons
• Welding specifications: Types of welds, locations, and techniques required
• Sectioning points: Where panels can be safely cut if partial replacement is allowed
• Material requirements: Steel grades, adhesives, and sealers to use
• Calibration procedures: ADAS and safety system requirements after repairs

Why OEM methods matter

Following OEM repair methods is important because:

• Safety: Procedures are designed to restore the vehicle's crash protection to original specifications
• Warranty: Non-OEM repairs may affect manufacturer warranty coverage
• Value: Properly repaired vehicles retain more resale value
• Insurance: Some insurers require OEM repairs for certain claims

OEM parts vs aftermarket parts

OEM repair methods often specify OEM parts, but the choice between OEM and aftermarket parts is separate:

• OEM parts: Made by or for the vehicle manufacturer, guaranteed to fit and match original specifications
• Aftermarket parts: Made by third-party manufacturers, may vary in quality and fit
• Used/salvage parts: Genuine parts recovered from other vehicles

Your insurance policy may specify which types of parts are covered.

How to verify OEM methods are used

To ensure your vehicle is repaired according to OEM specifications:

• Ask if the repairer has access to OEM repair information
• Confirm they have the necessary equipment and training
• Request documentation showing procedures followed
• Check if the repairer is OEM-certified for your vehicle brand
