If you need a replacement car part and your budget is tight a wrecker may have just what you are looking for. Whether you’re repairing an older vehicle or simply looking to save money on maintenance, car wreckers carry thousands of parts recovered from vehicles that have come to the end of their road. Not all parts will fit all vehicles, but knowing what is generally available can help you decide if a trip to a local wrecker is worth your time.
1. Engines and Engine Components
One of the most practical reasons people come is to find a second-hand engine at a wrecker. A new replacement engine can run thousands of dollars but a salvaged unit from a wrecker is often available for a fraction of that price. The catch is the engines have to be the same make, model, year and engine size as your vehicle. A 4-cylinder gasoline engine just won’t fit where a V6 should be, and an older engine may have different emissions equipment than a newer one.
If you’re looking at a used engine, check the colour and consistency of any oil present. Dark, sludgy oil is a sign of poor maintenance. If it is in reverse, listen for any clunking or grinding. Ask the wrecker for the engine number and verify it with your vehicle’s specifications. Wreckers also have smaller engine parts like cylinder heads, fuel injectors and water pumps available and often at a much lower price than new parts.
2. Gearboxes and Transmissions
Automatic and manual gearboxes from wrecked vehicles are serious money when you need one. The wrecker’s salvaged stock is attractive because a new replacement box can easily run $1,000 to $3,000 or more. But transmission condition is crucial. If your gearbox is shifting harshly, slipping between gears or making a grinding noise, it could be internal damage that’s not immediately obvious.
If you are looking at a used transmission, have the wrecker run it through the gears if possible. Make sure the fluid is bright red or pink, not dark brown or burned-smelling. Make sure it is the correct type for your vehicle (some have different gear ratios or bolt patterns). Many wreckers will pull a transmission and test it for you before you buy. Worth the extra cost for peace of mind.
3. Alternators and Starter Motors
The alternator and starter motor are what charge and start your engine . Usually can be found at wreckers . They are electrically pretty simple components and so are good candidates for being bought second-hand. A failing alternator will fail gradually and a starter that doesn’t crank may just need to be replaced rather than rebuilt.
Before you buy, have the wrecker check alternator output or starter engagement. There should be no evidence of corrosion, burned wiring or damage in a visual inspection. These parts are normally easy to change yourself or get fitted by a mechanic, which keeps labour costs down compared to more complex components.
4. Headlights and Tail Lights
Perth’s roads are no strangers to broken headlights and cracked tail lights. New light clusters cost a lot for newer vehicles, and wreckers often have perfectly good units that just need to be removed from their original vehicle. Modern headlight and tail light assemblies are sealed units if the lens is intact and the bulb works you’ve got a usable part.
Check that the lens is not yellowed or cloudy (it will reduce light output) and that there is no water inside the assembly. Verify the model number is the same as your vehicle. LED headlights and projector units are more common on newer cars and more expensive to replace, making them especially popular at wreckers. Older cars often have simpler sealed-beam headlights or basic reflector units that are cheaper to buy new, so it all depends on your particular vehicle.
5. Doors and Body Panels
Accident damage means you always have doors, bonnets, boot lids and wing panels readily available from wreckers. These parts are cosmetic only unless structurally damaged, which makes them easy to assess. The door opens and closes smoothly, and has no big dents or splits, and is ready to be installed. Check paint colour matches or live with having to respray.
Doors from vehicles of different model generations may not fit, please confirm the exact year and variant before purchase. On certain cars the door width or hinge location will change from one generation to the next. Interior door trim cards and window regulators are also common and useful interior restoration projects.
6. Side Mirrors
Cracked mirror glass and damaged mirror housings are surprisingly common and replacement mirrors at the dealer can be costly. Wreckers carry full mirror assemblies, which often include the glass, motor (for electric mirrors) and trim pieces. Check that electric mirrors work smoothly. Glass should not be cracked or fogged.
Check that the mirror is the correct side you need, left and right mirrors are not interchangeable. Most modern heated mirrors or blind-spot detectors add value to the part, so a complete assembly from a wrecker is often a better value than just buying the glass.
7. Wheels and Wheel Components
Perth wreckers generally have plenty of wheels in different sizes and styles. Whether you need steel wheels, alloy wheels or a full set, the price is often less than retail. However check the condition of the tyre and check the wheel itself for cracks, bending or corrosion. A wheel that has been damaged in an accident may be cheaper but it may not be safe.
Ensure the offset and size are compatible with your vehicle. Tyres on salvaged wheels could be at the end of their life so think about replacement costs. Brake rotors, pads, callipers and ABS sensors are also readily available. Parts wear out on a regular basis, so check for signs of wear or damage before purchasing.
8. Suspension Components
Wreckers regularly stock springs, struts, control arms and sway bars. If the suspension parts are in good condition, as they wear gradually, used parts are a possibility. Stay away from springs that are obviously compressed and struts leaking oil from the rod. The control arms should be free-moving and not cracked or bend.
Condition is more important here than with purely cosmetic parts because suspension work affects how your car handles and brakes. If you don’t know, have a mechanic check a second-hand suspension part before you buy it. Newer vehicles often feature better engineered parts, so scavenged components from more recent models may perform better.
9. Interior Parts and Seats
At wreckers, car seats, dashboards, door panels and carpets are easy to get off and often in good condition. Leather seats from wrecked cars can be a major upgrade to the interior of an older car. Check seats for stains, tears and frame damage. Check electric seat motors for free movement and test heating elements.
Interior trim pieces vary greatly from vehicle to vehicle, and are rarely interchangeable. Please verify fitment with your specific vehicle. Wreckers can also sell you carpet sets and acoustic panels, which are great for older vehicles with worn floors, but newer vehicles often come with integrated floor mats that aren’t easily transferable from car to car.
10. Electrical Components and Accessories
Wreckers carry a lot of electrical parts in addition to alternators and starters, including window motors, power lock actuators, instrument clusters, switches and relays. These components are either working or they’re not, so they’re easy to test. Before buying, have the wrecker bench-test electrical items. Window motors should operate quietly and smoothly and instrument clusters should light up and show normal readings.
We also have electrical accessories such as completed wiring looms, fuse boxes and distribution boards. These save big bucks if your restoring a vehicle or doing electrical repairs.<br/><br/> Before buying, check for burned connections, corrosion or obvious damage.
Used vs New Parts: When Does It Make Sense?
There are times when buying used car parts is not the best choice, but there are other times when it makes perfect sense. New parts come with manufacturer guaranties, improved longevity and guarantyd compatibility. Used parts are cheaper but riskier in terms of durability, compatibility, and condition.
The decision is usually based on the type of part, your vehicle’s age and your budget. If the vehicle is older, the resale value is limited, and the cost of a new replacement part is high, a quality used component makes economic sense. For safety critical items such as suspension or brakes it is usually worth the cost to buy new. Parts that are regularly replaced, such as alternators or water pumps, are often fine to use, especially if they have been tested. Cosmetics that are low risk, such as doors or mirrors, are easy to assess in terms of condition.
The age and rarity of your vehicle also matter. If you’ve got a 10-year-old Toyota, new parts are cheap and easy to find. If you’ve got a rarer car, wreckers may be your only real option for discontinued parts. Also consider your own mechanical knowledge – fitting a used part yourself will save on labour costs, but tricky replacements might be best left to professionals, which adds to the overall expense.
Choosing the Right Used Part: What to Check
Before you hand over your cash, make sure it’s compatible and in good condition. Begin by entering the make, model, year and engine type of your vehicle. Have your vehicle identification number (VIN) handy so the wrecker can cross-reference parts properly. Some components have specific part numbers that need to be exact matches.
Check the part visually. Inspect the mechanical components for obvious damage, corrosion, cracks or excessive wear. Cleanliness counts too – a heavily oiled or dirty engine part might hide damage. For electrical items, find out if the wrecker can test the part or see how it works. When checking body panels, check the paint, dents and alignment.
Ask if the wrecker has any sort of warranty or test drive period. Many wreckers will guaranty their parts for a short time if they fail right after fitting. See if you can return or exchange the part if it doesn’t fit or work out. If you have any doubts about compatibility, take a mechanic you trust to check it out before you buy, especially mechanical or electrical parts.
Frequently Asked Questions
Q: What car parts can I buy from a wrecker?
Wreckers carry engines, transmissions, doors, windows, lights, wheels, seats, electrical components and more. Availability depends on existing stock and vehicles being broken for parts. Since not all wreckers will have all parts, it is worth calling ahead to see if they have the part you need.
Q: Are used car parts cheaper than new parts?
Yes, generally especially for engines, transmissions and complete assemblies. A used engine might be half the price of a new one. But simple things like alternators or lightbulbs might not be much more expensive new or second hand. Depending on the part type and your car, you can save quite a bit of money.
Q: How do I know if a used car part will fit my vehicle?
Please confirm your vehicle make, model, year and engine type. Find the original part number from your mechanic or owner’s manual and cross reference with the wreckers part. Don’t assume parts from similar vehicles will fit, as different generations often have incompatible parts even if they look similar.
Q: Are used engines and transmissions worth buying?
They can be, especially on older vehicles where there is no option of expensive new replacements. However, these parts must be examined thoroughly and often professionally tested or installed. You might be able to get a low mile wrecker engine that runs well, depends on condition and compatibility.
Q: What should I check before buying a used car part?
Verify compatibility with your specific vehicle, inspect condition for damage or wear, test electrical components if possible, check for corrosion or oil leaks, and confirm fitment with a mechanic if you’re unsure. Don’t rush the decision—take time to examine the part thoroughly before purchase.
Conclusion
Car wreckers provide a cost effective way to find replacement parts instead of buying them new. If you are running an older car on a budget or are looking for a hard-to-find part, wreckers often have what you need – if you know what to look for and how to check the condition and compatibility.
The secret is to do your homework. Know your vehicle’s specs, inspect parts thoroughly, test what you can test, and don’t be afraid to walk away from something if it doesn’t feel right. For some repairs, it is worth spending a little more on a new part for peace of mind. For some, a quality second hand component from a reputable wrecker is a good financial decision.
