**Jeep Cherokee, Liberty, Renegade 2003 Parts Catalog** – Factory Part Numbers, Not Guesses

I’ve watched a lot of junkyard scavengers and home-garage guys order the wrong part because they looked at a blurry photo on a forum instead of the factory diagram. You don’t get second chances on return shipping. This 2003 parts catalog gives you the exact OEM part numbers for the Jeep Cherokee, Liberty, and Renegade. No aftermarket reinterpretations. No guesses. You decode your VIN, flip to the group, and you read the number off the page.

612 Pages of Factory Part Numbers

This is a DaimlerChrysler-published document, not a repackaged third-party file. It runs 612 pages and covers every Mopar accessory and production component for the 2003 KJ platform. The table of contents starts with Group 1 – Component Parts for Mopar Accessories, which includes audio and electronics, carriers and cargo hauling, driving convenience, exterior appearance, exterior protection, fog lights, interior storage, and security systems. You get figure numbers like Fig. 1-111 for the CD changer player kit, Fig. 1-212 for the roof bike carrier, and Fig. 1-310 for the speed control package. Every figure has an illustration and a list of part numbers. You don’t have to call the dealer and hope the parts guy is having a good day.

VIN Decoding: Getting the Right Parts

Page 1 of the catalog has the full VIN plate decoding table. It tells you exactly what each character means. Position 4 gives GVWR ranges in pounds – from 3001-4000 lbs up to 10001-14000 lbs. Position 5 tells you if it’s a Liberty 4×2, Liberty/Cherokee 4×4 left-hand drive, or right-hand drive. Position 6 tells you the series: Sport, Renegade, or Limited. Position 8 decodes the engine – 2.4L gas, 2.5L diesel, 3.7L V6, or 2.8L diesel. If you skip this step you’ll order parts for the wrong engine. I’ve seen it happen. Don’t be that guy.

Front and Rear Axle Diagrams

Group 2 covers front suspension and drive. You get suspension and strut diagrams (Fig. 2-110), front sway bar (Fig. 2-120), axle shafts (Fig. 2-210), axle housing (Fig. 2-310), front axle assembly (Fig. 2-410), front differential (Fig. 2-610), and front axle skid plate (Fig. 2-810). Group 3 goes into the rear axle – the Corporate 8.25 assembly (Fig. 3-110) and differential and housing (Fig. 3-210). If you need a vent part, Fig. 3-310 is right there. No digging through service manuals that hide the part numbers in a different section.

Does This Catalog Include Torque Specs?

No. This is a parts catalog, not a service manual. You won’t find torque values, repair procedures, or diagnostic charts. If you need those, get the factory service manual – check out the 2005 Jeep Liberty (KJ) Service Manual or the 2002-2007 Jeep Liberty KJ Service Manual for the full service data. For older Jeep parts, the 1994-1996 Jeep Parts Catalog covers those model years. The Automotive Industry Overview on Wikipedia gives context on how OEM standards are maintained, but for hands-on work you need factory documents.

3 Reasons to Use OEM Documentation

First, aftermarket catalogs often combine years and trim levels, leading to wrong part numbers. Second, this catalog includes Mopar accessories that aftermarket systems ignore entirely – like the EVS II alarm system (Fig. 1-910 and Fig. 1-914) or the dog guard kit (Fig. 1-810). Third, the part numbers here match exactly what the dealer uses. You bring the number to any parts counter or search online and you get the right piece. No cross-reference headaches. Automotive Industry Overview discussions show why factory data is the standard for reliability.

Brake and Clutch Group Coverage

Group 4 covers parking brake lever and cables (Fig. 4-110) and rear disc parking brake assembly (Fig. 4-120). Group 5 goes into service brakes – front brakes (Fig. 5-110), rear disc brakes (Fig. 5-210), power brake booster (Fig. 5-310), master cylinder (Fig. 5-410), brake lines for LHD and RHD, and brake pedals (Fig. 5-610). Group 6 covers the clutch itself (Fig. 6-110), clutch housing (Fig. 6-210), clutch control (Fig. 6-320), and pedal clutch (Fig. 6-420). Every figure lists the individual components. You can order a specific clip without buying a whole assembly.

Cooling System Parts by Engine

Group 7 is all cooling. Each radiator and related parts figure is split by engine: Fig. 7-110 for 2.4L, Fig. 7-120 for 3.7L, Fig. 7-130 for 2.5L and 2.8L diesel. Same for water pumps, coolant tanks, drive pulleys, and drive belts. If you’ve got the 2.8L diesel, you look at Fig. 7-320 for the degasser tank. The part number is right there next to the diagram.

FAQ

Is this a service manual?

No. It’s a parts catalog. You don’t get torque specs or repair steps.

Does it cover all engine options?

Yes. It covers 2.4L gas, 2.5L diesel, 3.7L V6, and 2.8L diesel. See the VIN decoding table on page 1 to identify your engine. The catalog then lists parts specific to each engine group. That’s why you need to decode your VIN first. If you skip that step you’ll end up with the wrong water pump or radiator.

Can I use this with aftermarket parts?

You can, but factory part numbers are tied to OEM parts. Aftermarket cross-references are not guaranteed. Use at your own risk.

Does the catalog include diagrams?

Yes, each figure has an illustration and a list of part numbers. You see the shape and the number together.

You need a part number that matches your VIN and build date, not a generic guess. This catalog gives you the factory data in 612 pages. Get the right number the first time. Access the Factory Manual.
