5 Things to Check Before Buying Used OEM Parts
Buying used OEM parts can be a smart and economical decision. Whether you're fixing your personal vehicle, managing an auto repair business, or maintaining a commercial fleet, opting for used OEM parts often provides a reliable and budget-friendly solution. However, it's important to remember that not all used OEM parts are created equal. If you’re not diligent, you could end up with a part that’s incompatible, faulty, or more trouble than it’s worth.
Having worked closely with a wide range of vehicle owners, mechanics, and auto service professionals, I’ve seen both the upsides and the pitfalls firsthand—everything from outstanding finds to regrettable purchases. To help you avoid costly mistakes and ensure a smooth repair process, here are the five key things you should always verify before purchasing used OEM parts in California.
Why Used OEM Parts are a Smart Choice?
Cost Savings
Let’s be honest—vehicle repairs can quickly become expensive. Choosing used OEM parts can dramatically reduce those costs, often by 50% or more, all without compromising on quality. I once had a customer who needed a replacement alternator for their truck. A brand-new one was priced at $400, but they found a used OEM part for just $150—and it performed just as reliably.
Availability for Rare or Older Models
If you drive an older or less common vehicle, sourcing new parts can be frustrating and time-consuming. That’s where used OEM parts come in handy. Many suppliers maintain a diverse inventory that includes components for discontinued models or rare vehicles, making it easier to find exactly what you need.
Environmental Impact
Opting for used OEM parts isn’t just good for your wallet—it’s also good for the planet. Reusing original equipment manufacturer parts helps minimize landfill waste and supports environmentally responsible practices. Every time you choose a recycled part, you're contributing to a more sustainable automotive industry.
5 Things to Check Before Buying Used OEM Parts Online
1. Verify Compatibility with Your Vehicle
The first rule of buying used OEM parts: ensure it’s the right fit for your vehicle! Compatibility goes beyond just the make and model—it involves matching the exact specifications required for proper performance.
· Check the Part Number: Look for the original equipment manufacturer (OEM) part number either on your old part or in your vehicle’s service manual.
· Use Your VIN: Your Vehicle Identification Number can help confirm whether the part is a match, especially for complex components like transmissions, engines, or electronic modules.
Pro Tip: I once helped a friend replace a side mirror on their SUV. We found what looked like the perfect used OEM part, but when we went to install it, we discovered it was meant for a different trim level. The mounting points didn’t line up. That experience was a clear reminder: double-check every detail before buying.
2. Inspect the Part’s Condition
Even the right used OEM part won’t do any good if it’s damaged or excessively worn. A thorough inspection is crucial before making a purchase.
· Look for Visible Damage: Check carefully for cracks, rust, corrosion, or worn-out areas that may compromise the part’s function.
· Inspect Moving Components: If the part includes moving mechanisms—like bearings, hinges, or fans—make sure they move smoothly without sticking or feeling overly loose.
A trusted mechanic once showed me a radiator he had bought second-hand. It looked fine at first, but upon closer inspection, he spotted tiny cracks along the seams—something that could’ve caused serious leaks later. That quick check saved him time, money, and frustration.
3. Ask About the Part’s History
Understanding the history of used OEM parts can offer valuable insight—and help you avoid potential problems.
· Ask About Mileage: For components like engines, transmissions, or brake rotors, mileage matters. These parts have a limited lifespan, so it’s important to know how much wear they’ve already seen.
· Check the Source: Find out whether the part was removed from a functioning vehicle or one involved in an accident. Parts salvaged from heavily damaged vehicles may have hidden defects that aren’t immediately visible.
Pro Tip: A customer once inquired about a low-cost used OEM battery. When we contacted the supplier, they admitted it had been sitting unused for years. Batteries can degrade over time even without use, so it turned out to be a poor investment.
4. Check for a Warranty or Return Policy
Not every seller offers a guarantee on used OEM parts, but many reputable suppliers provide at least a limited warranty—something that can be a lifesaver if a part fails sooner than expected.
· Understand the Terms: Does the warranty cover both the part and installation? How long is it valid? What’s the return process?
· Prioritize Reputable Suppliers: A reliable supplier who stands behind their parts is more likely to sell high-quality, tested components.
Example: A repair shop I worked with once purchased a used OEM alternator that failed within a week. Fortunately, the supplier had offered a 90-day warranty, allowing them to exchange the part at no additional cost.
5. Compare Prices and Suppliers
The cost of used OEM parts can vary significantly between suppliers. Doing a bit of research can protect your budget and your vehicle.
· Research Market Rates: Check prices from multiple vendors to understand what a fair deal looks like.
· Check Reviews: Look for sellers with solid customer feedback and a proven track record for quality parts.
Warning: I once came across a vendor selling used engines at unusually low prices. After some investigation, I found out they didn’t test their parts before selling them, resulting in high failure rates. It’s a reminder that the cheapest option isn’t always the best one.
Bonus Tips for Buying Used OEM Parts
Buy from Reputable Suppliers
When purchasing used OEM parts, always choose trusted suppliers—especially those certified by organizations like the Automotive Recyclers Association (ARA). Certified suppliers adhere to strict industry standards, ensuring the quality, reliability, and safety of the parts they sell.
Know Which Parts Are Safe to Buy Used
Not all components are created equal when it comes to buying used OEM parts. Many parts—such as body panels, mirrors, wheels, and rims—are generally safe to purchase used. However, critical safety components like airbags, seat belts, and brake pads should always be bought new to ensure maximum protection.
Keep Documentation
Always request a receipt and any available documentation detailing the used OEM part’s origin, condition, and warranty coverage. Having this paperwork can make the return or replacement process much smoother and protect you in case of disputes or warranty claims.
Conclusion
Purchasing used OEM parts is a practical and economical choice for anyone maintaining or repairing a vehicle. When done right, it offers significant cost savings, greater access to parts for older models, and a more sustainable approach to automotive repairs. The key is to buy smart—verify compatibility, inspect each part carefully, ask about its history, and always choose trusted suppliers. Not all parts are safe to buy used, so it’s important to know the difference and prioritize safety when necessary.
