Chevrolet Y Parts Catalog – 1997-2001 (OEM Factory Print)

If you’ve ever ordered a water pump for an LS1 and got the wrong one because you trusted a third-party parts lookup, you know the pain. The Chevrolet Y Parts Catalog cuts that crap out. This is the factory document – 1348 pages of OEM part numbers, exploded views, and grid coordinates that match what the dealer pulls up on his terminal. No translation errors, no “fits all models” nonsense.

Engine Assembly Breakdown: LS1 vs LS6

The catalog separates the 5.7L V8 into LS1 and LS6 variants by year – something aftermarket charts often miss. Page 1 shows the index with grid references like “1-G2” for cylinder block assemblies. You get separate sections for 97-98 and 99-01 cylinder heads, front covers, oil pumps, even the LS6-specific parts from 2001. The Engine section alone covers 13 subassemblies, each with a dedicated illustration and part-number list. Need a Cylinder head bolt for a 2001 LS6? The catalog pinpoints it by year and RPO code.

Cooling System Parts: Radiator and Fan Assemblies

Under “Engine Cooling and Accessories” you get radiator assemblies split by transmission type (MM6 vs M12), coolant fan parts, block heater (K05), and all hoses and pipes. The 1997-2000 radiator is a different PN than the 2001 model – the catalog tells you why. Page 2 lists part numbers with quantities and even the AC-Delco cross-reference (e.g., oil filter cap RC73). You won’t find that level of detail in a Chilton.

Fuel System Coverage: From Injector Rails to Throttle Bodies

The Fuel, Air Intake and Exhaust Systems section breaks down the fuel supply system year by year (97-98, 99, 00, 01-02). Fuel injector rails are shown for both LS1 and LS6, part numbers for throttle bodies, and the AIR pump with separate hose diagrams. If you’re swapping a cam and need the factory injector rail, this is where you find the OEM number. Every fastener, every seal – it’s all there.

Transmission Section: Manual and Automatic Breakdown

Manual transmissions MM6 and M12 get their own exploded views, with shift controls and clutch linkage (page 1 lists the clutch linkage section). The automatic section (4L60E) is divided into four parts: case, clutch gears, control valve, and oil pump. Each part has separate page references in the PDF bookmarks. No guessing which torque converter bolt pattern you need – the catalog gives you the exact assembly drawing.

3 Reasons to Use an OEM Parts Catalog

Aftermarket catalogs often consolidate years and RPO codes, leading to wrong parts. This catalog is printed from GM’s own service parts operations. It uses the same illustration numbers and grid system that dealership parts counters use. When you order a part based on this catalog, the counter guy can cross-check it instantly. Also, the electrical section includes battery cables, alarm systems, and lamp assemblies with year-specific variations. If you’re chasing an intermittent no-start, check the anti-theft alarm section – the part numbers for the control module changed in 2000.

Who Needs This Catalog?

DIY guys rebuilding an LS1 Corvette or Camaro (Chevrolet Y-body). Professional techs who need to source correct hardware without digging through GM’s electronic system. Shop owners who want to cut down on returns due to wrong parts. This catalog covers 1997 through 2001 model years, including the 1999-2000 manifold changes and the 2001 LS6 oil pump. If you’re working on a 1997-2001 Y-body and you don’t have this, you’re guessing. And guessing costs time and money.

Source Authenticity: Factory Print, Not a Scan of a Reprint

This PDF is a direct scan of the original GM Parts Catalog, document number 19714001299. The OCR excerpt on page 2 shows real part numbers like 12559604 (valve rocker arm cover, LH) with quantities and notes. The index on page 1 uses a grid coordinate system (e.g., 1-F7) that matches the physical dealer binder. Anything claiming to be a “generic” parts catalog for the Chevrolet Y is just a rehash of this. Why trust a third-party when you can have the original? For a broader context on automotive part numbering, check the Automotive Industry Overview at Wikipedia. If you also work on trucks, the Chevrolet, GMC Silverado, Sierra, Avalanche 2003 Installation Manual follows the same OEM format. For another SUV manual, the Chevrolet TrailBlazer User Manual – 484 Pages of Factory Specs is similarly detailed. And if you need the F-Body parts catalog for cross-referencing, the Chevrolet F-Body 1993-2002 Parts Catalog is a direct companion.

FAQ

Does this catalog include torque specifications?

No. This is a parts catalog – it lists part numbers, quantities, and assembly relationships. Torque specs are found in the service manual for the same vehicle. That said, the illustrations show fastener locations, which helps you know which bolts get replaced.

Will this catalog help me rebuild an LS1 engine?

Absolutely. It shows every internal part from the cylinder block to the valve covers, with separate sections for cylinder head, front cover, oil pump, and manifolds. You can identify individual gaskets, seals, bolts, and even valve spring shims.

Is the catalog searchable?

Yes – the PDF includes the original bookmarks and OCR text, so you can search for part numbers or descriptions. The grid coordinates in the index also let you jump directly to the right page.

What about the battery?

Battery cables and related parts are under Section 2 (Electrical Systems), with separate listings for 97-00 and 01-02. For battery specifications, check Automotive Battery on Wikipedia for general guidance, but the catalog gives you the OEM cable part numbers and mounting hardware.
