Buying used auto parts can save you money while helping the environment, but navigating the terminology and emission codes involved can be overwhelming. Whether you’re new to the world of auto salvage or simply want to better understand the jargon, this guide will break down the most common terms you’ll encounter. We’ll also delve into emission codes and their importance when purchasing used parts, ensuring you’re equipped with the knowledge to make informed decisions.
1. Understanding Auto Salvage Terms: A Glossary for Buyers
When buying used auto parts, you’ll come across a variety of specialized terms. Here’s a glossary of key auto salvage terms to help you understand what to expect and how to shop smarter:
A. Salvage Title
A salvage title is issued when a vehicle has been deemed a total loss by an insurance company. This usually happens when the cost of repairs exceeds the vehicle’s value. Salvage title cars are often sold for parts, as the components can still be in good condition.
B. OEM (Original Equipment Manufacturer) Parts
OEM parts are components made by the vehicle’s original manufacturer or a licensed supplier. They are designed to fit your vehicle’s specifications and maintain its performance standards. OEM parts are often considered more reliable but may be priced higher than aftermarket alternatives.
C. Aftermarket Parts
Aftermarket parts are made by third-party manufacturers and are designed to fit a wide range of vehicles. These parts are often cheaper than OEM parts, but quality can vary. It’s important to check compatibility and warranty information when choosing aftermarket parts.
D. Used Parts
Used parts are components that have been removed from a vehicle that is no longer in service. They can be an affordable alternative to new parts, and many used parts are still in great condition, making them a viable option for repairs and replacements.
E. Rebuilt Parts
A rebuilt part has been repaired or restored to a condition that is as close as possible to its original state. This can include re-machining, cleaning, or replacing worn-out parts. Rebuilt components are typically tested for quality and reliability before being sold.
F. Certified Parts
Certified parts have been tested and inspected to ensure they meet specific standards of quality. These parts may be used, rebuilt, or remanufactured, but they are guaranteed to function properly and are often sold with a warranty.
G. Dismantler
A dismantler is a professional or company that takes apart vehicles for the purpose of salvaging usable parts. These professionals play a vital role in the used auto parts industry by providing quality components to buyers at a fraction of the cost of new parts.
2. Emission Code Glossary for Used Parts
Emission codes are essential when purchasing used auto parts, especially if you’re concerned about your vehicle’s emissions compliance. Here’s a breakdown of common emission-related terminology to help you understand what to look for:
A. OBD-II (On-Board Diagnostics II)
OBD-II is a diagnostic system in vehicles that monitors the engine and emissions systems. OBD-II codes are used to identify problems that may affect a car’s emissions. Many states require vehicles to pass OBD-II emissions testing as part of their registration process. If you’re buying used parts, ensure they are compatible with your vehicle’s OBD-II system for optimal emissions control.
B. EPA (Environmental Protection Agency)
The EPA sets standards for vehicle emissions in the United States. When purchasing used parts, you’ll often encounter references to EPA certifications. EPA-approved parts meet federal emissions requirements, ensuring they do not negatively impact air quality.
C. CARB (California Air Resources Board)
The CARB sets even stricter emissions standards than the EPA, specifically for California. If you live in California or another state that follows CARB regulations, it’s important to ensure that the used parts you buy are CARB-certified. This is especially relevant for components like catalytic converters and exhaust systems.
D. EGR (Exhaust Gas Recirculation) System
The EGR system helps reduce nitrogen oxide emissions by recirculating a portion of the engine’s exhaust back into the combustion chamber. When purchasing used parts related to the EGR system, check for compatibility with your engine to ensure your vehicle meets emissions standards.
E. Catalytic Converter
A catalytic converter is an emissions control device that reduces harmful pollutants in a vehicle’s exhaust. When buying a used catalytic converter, it’s crucial to ensure it meets EPA or CARB standards and is free from damage or wear that could affect its efficiency.
F. Emissions Compliance
Emissions compliance refers to whether a vehicle or its parts meet local, state, or federal emissions standards. When purchasing used auto parts, especially those related to the exhaust or fuel systems, it’s important to verify that the parts are emissions-compliant to avoid failing inspections or causing damage to the environment.
G. Non-CARB Compliant
Some used parts may be non-CARB compliant, meaning they do not meet the stringent emissions standards set by the California Air Resources Board. If you live in California or another state that follows CARB rules, it’s essential to avoid these parts unless they are specifically exempted.
3. Why Emission Codes Matter When Buying Used Auto Parts
Understanding emission codes and regulations is critical for ensuring your vehicle remains compliant with environmental laws. Failing to use the correct emissions-compliant parts can result in:
- Failed Emissions Inspections: Most states require vehicles to pass emissions tests. Using non-compliant used parts can cause your car to fail these inspections.
- Increased Environmental Impact: Using substandard parts that don’t meet emissions standards can contribute to air pollution and hinder efforts to reduce carbon emissions.
- Legal Consequences: In some regions, using non-compliant parts may result in fines or legal issues, especially for vehicles that are subject to stringent emissions testing.
When buying used parts, always ensure they meet the required emission codes to avoid these issues.
4. Frequently Asked Questions (FAQ)
1. What’s the difference between OEM and aftermarket parts?
- OEM parts are made by the original manufacturer and are designed specifically for your vehicle, while aftermarket parts are made by third-party manufacturers and may not be an exact match for your vehicle’s specifications. OEM parts tend to be more expensive but offer a higher level of assurance in terms of fit and performance.
2. How do I know if the used parts I’m buying meet emission standards?
- Ensure the parts are either EPA-approved or CARB-compliant, depending on your region. Always check for certification labels or ask the supplier for proof of emissions compliance.
3. Can I use non-CARB compliant parts in my vehicle?
- In states that follow CARB regulations, such as California, you must use CARB-compliant parts. Using non-compliant parts could result in a failed emissions inspection, fines, or legal issues.
4. Are used parts as reliable as new ones?
- Used parts can be just as reliable as new ones, especially if they are certified and have been thoroughly tested. Always buy from reputable suppliers who inspect and grade their used parts to ensure quality.
5. What is the importance of understanding emission codes when buying used parts?
- Emission codes ensure that the parts you purchase meet local, state, and federal environmental standards. Non-compliant parts can lead to legal trouble, failed inspections, and environmental harm.
