Car Parts, Auto Tools and Supplies

Where each kind of car job lives in this aisle

The aisle follows what you want to do. Repairs lead to spare and repair parts and to tools; routine maintenance means fluids and oils, filters and gaskets; appearance work covers cleaning, detailing, paint, trim and styling; upgrades cover tuning parts, wheels and tire gear. Decide which of the four jobs you are doing, since the questions differ: parts need exact fitment, fluids need the right specification, and accessories mostly need the right size.

Fitment, part numbers and specifications that must match

Start with year, make, model and engine, then confirm against the part number on the old component or the vehicle identification number. Trim level, drivetrain and production date can change which part fits, and many parts are sold per side, so read the fitment notes. Fluids follow the specification in the owner's manual: oil viscosity grade, coolant chemistry and brake fluid class. A part that looks right but differs in one dimension or connector will not do.

Questions about Car Parts, Auto Tools and Supplies

How do I find the right part for my car?

Gather your vehicle identification number and, if possible, the number on the old part. Compare both against the listing's fitment notes. Pictures can mislead, because trim, drivetrain and production date can change which version fits.

Can I use a different oil viscosity than the manual says?

Stay with the grade and specification in the owner's manual unless the maker approves alternatives. Viscosity affects oil pressure, protection and cold starts, and some engines need oil that meets a named standard, not just a grade like 5W-30.

Does left side mean driver's side?

In North American listings, left usually means the driver's side, and right the passenger side. In other markets the sides can be reversed, so confirm in the description whether the part is for a left-hand-drive vehicle, or compare it with the old part.
