Mazda 3 2004 Parts Catalog – Factory OEM Part Numbers

You’ve got a Mazda 3 on the lift. Maybe it’s a hatchback, maybe a sedan. You pull a front bumper cover, and the retaining clip snaps. Now you’re digging through aftermarket catalogs hoping the part matches. That wastes time, and time costs money. This Mazda 3 2004 Parts Catalog is a factory-original print – 19 pages of nothing but OEM part numbers, exploded diagrams, and the exact hardware you need. No guesswork, no cross-referencing a third-party book that’s wrong half the time. If you’ve ever ordered a tow hook cover and got the wrong color code, you know what I mean.

ABS/Brakes Section: Why You Need the Right Part Numbers

The ABS/BRAKES section on page 4 lists every component from the modulator to the wheel-speed sensor. A buddy of mine once used an aftermarket brake hose that had a different banjo bolt thread – ended up with a leak. This catalog gives you the factory number for the hose, the banjo bolt, even the copper washers. If you’re replacing an ABS control unit, you get the exact part code, not a “compatible with” guess. You want to avoid having to re-bleed the system twice? Use the OEM number from this manual.

Cooling System: Radiator, Hoses, and Thermostat

Page 3 covers A/C/HEATER/VENTILATION and COOLING. The radiator for a 2.0L manual trans has a different part number than the 2.3L auto. The catalog breaks it down by engine code, transmission type, and even model year variations. You get the fan shroud, the coolant reservoir cap, the lower hose routing – all with factory part numbers. If you’re rebuilding a front-end after a collision, this is the sheet you tape to your bench so you don’t order the wrong radiator.

Electrical Section: Avoiding the Guesswork When Sourcing Parts

Electrical systems are where most DIY guys get burned. The ELECTRICAL section on page 7 lists harness connectors, fusebox components, and lighting assemblies. Need a rear lamp assembly? Page 19 gives you the part number for the left and right units, including the bulb socket and housing. The catalog also includes the AIR BAG SYSTEM section (page 4) with caution labels and sensor locations – critical safety stuff. Never trust an aftermarket wiring diagram; these are the actual Mazda engineering drawings with correct pinouts and connector part numbers.

Fuel Tank and Suspension: OEM vs Aftermarket – One Clear Winner

The FUEL TANK section (page 17) lists the tank assembly, filler neck, hoses, and even the fuel pump module. The REAR SUSPENSION section (page 17) covers control arms, springs, and shock absorbers. I’ve seen aftermarket coil springs that sag after 10,000 miles because the steel grade is different. This catalog gives you the Mazda-spec spring rate and part number. Same for the FRONT SUSPENSION (page 5) – ball joints, tie rod ends, stabilizer bar links. You order the factory part, it fits, it lasts. No reprints, no third-party copy – this is a direct scan of the official Mazda parts book.

3 Reasons This Factory Print Beats Any Aftermarket Manual

First, the part numbers are verified by Mazda engineering, not some editor guessing. Second, the exploded diagrams show the exact assembly order and fastener locations. Third, the paint and trim codes (like Arctic White A4D or Velocity Red 27A) are listed with the correct suffix letters – miss one letter and the color won’t match. If you’re doing a body repair, the FRONT BUMPER and REAR BUMPER sections (pages 1 and 19) list every clip, retainer, and absorber. You get the bolt part numbers for the reinforcement bar – those torque-to-yield bolts aren’t something you reuse.

Look, I’ve been turning wrenches for 28 years. I’d rather have a 19-page factory parts catalog for a specific model year than a 1,000-page aftermarket book covering ten years. The specificity saves you returns, wrong orders, and downtime. Automotive Industry Overview’>Industry standards back that up – factory data minimizes errors.

FAQ – Common Questions About This Parts Catalog

Does this catalog include torque specifications for suspension bolts?

No. This is a parts catalog, not a repair manual. It lists part numbers and exploded diagrams. For torque specs, get the corresponding workshop manual.

Can I use the part numbers here to order from my local dealer?

Yes. These are the original Mazda part numbers exactly as the dealer system uses them. The catalog includes supersession annotations in some sections – like the front bumper cover revised part for certain colors. Present the number to the parts counter; it will match.

How do I know which part number applies to my specific car?

Look up your engine code (2.0L or 2.3L) and transmission type (manual or auto). The catalog has separate listings for each variant. Also check the paint code location (page 1) – it’s on the driver door jamb. That code determines the exact color-coded trim parts like tow hook covers or mirror caps.

What is on page 19?

Page 19 contains the REAR BUMPER and REAR LAMPS sections, including the impact absorber, reinforcement bar, tail light assemblies, and the license plate holder. Also lists bumper cover color options for sedan/hatchback.

This catalog covers the Cooling, Electrical, Engine (mounts, under cover), Suspension (front and rear), Fuel system, and ABS. Every major system on the vehicle is broken down by component with factory part numbers. If you’re rebuilding a wreck, restoring a project, or just doing brake pads and rotors the right way, you need this pinned to your toolbox.
