Maintenance Parts
Compare maintenance parts, verify vehicle fitment, use the correct repair manual, and shop new, remanufactured, or used OEM options.
Find maintenance parts by component
Routine maintenance parts are usually the easiest place to compare new replacement brands while using the manual for intervals and specifications. Choose the component below to compare a sensible new-parts or used-OEM path, then verify the exact application before ordering.

Use a parts source that matches this system
Direct brands are shown only where their catalog overlaps this category. Amazon remains a broad new-parts and tools source, while eBay Motors is useful for factory, discontinued, exact-match, and used OEM components.
Approved partners for maintenance parts
Use these programs where their catalog matches the component you need. Verify fitment, part number, included hardware, and installation requirements before purchase.

Verify the vehicle and repair requirements first
Record VIN, build date, engine, transmission, drivetrain, trim, axle, wheel package, emissions family, and option codes that can change fitment.
Photograph the label or stamping and match the full manufacturer number, suffix, revision, connector, dimensions, side, and mounting points.
Check seals, fluids, one-time-use fasteners, torque values, special tools, bleeding, alignment, programming, relearn, or calibration before buying.
For modules, assemblies, remanufactured parts, and used OEM, verify testing, core charges, programming status, warranty, and return freight.
Maintenance Parts fitment and installation guide
| Component | Verify before ordering | Typical source | Check in the manual |
|---|---|---|---|
| Engine oil and filter | Engine, capacity, viscosity, filter size, drain-plug seal | New | Capacity, reset procedure, torque |
| Air and cabin filters | Body style, HVAC housing, engine intake design | New | Access direction, housing clips, airflow arrow |
| Spark plugs and ignition parts | Engine code, plug specification, gap, coil revision | New | Torque, anti-seize guidance, firing order |
| Belts and tensioners | Engine, accessory layout, belt length, pulley design | New | Routing diagram, tensioner release, inspection points |
| Fluids and service kits | Transmission, differential, transfer case, coolant, brake specification | New fluid and seals | Fill temperature, level procedure, bleed or relearn |
| Wiper and visibility items | Blade length, arm connector, washer system, lamp type | New | Service position, connector orientation, aiming |
Make sure the part is actually the failure
A fault code or symptom often identifies the system that needs testing, not the component that should automatically be replaced. Check power, grounds, wiring, fluid condition, mechanical movement, related sensors, fuses, relays, connectors, and service bulletins before ordering.
Diagnostic tools relevant to this system
These programs are included for diagnosis, service functions, programming, or calibration—not as substitutes for verifying the failed component.

Maintenance Parts questions
What is the most important fitment check?
The original part number is often the strongest single check, but it should be combined with VIN, engine, transmission, drivetrain, build date, option codes, connectors, and dimensions.
Should these parts be purchased new or used?
Wear items, seals, hoses, bearings, friction components, and maintenance parts generally belong in the new category. Used OEM can make sense for discontinued, exact-fit, body, trim, lighting, module, or assembly-level components.
What hidden costs should I expect?
Related hardware, fluids, seals, tools, alignment, bleeding, programming, calibration, core charges, shipping, and return freight can exceed the part-price difference.
Why can two parts that look identical be incompatible?
Internal calibration, software, connector keying, sensor type, dimensions, mounting, option content, and production revisions may differ even when the housings look alike.
