AM General DMAX 2006 Parts Catalog

I’ve been turning wrenches since before most of you were born. And the one thing that still drives me nuts is chasing a part number from a generic catalog that doesn’t match the casting sitting on my workbench. This AM General DMAX 2006 Parts Catalog is the real thing – OEM factory print from AM General, not some third-party rehash. You get exploded diagrams with exact AM General part numbers for every nut, bolt, and gasket on the DMAX powertrain. 647 pages of zero-guesswork parts identification.

Engine Assembly – Page 2 Breakdown

The engine chapter starts on page 2 of the PDF. You get the complete longblock assembly, the Duramax 6.6L with every component listed – from the cylinder head gaskets (two pages of them) to the front cover bolt kits. Each item shows the AM General part number and quantity required. I’ve used this to source parts for a head gasket job on an H1 and didn’t waste a single trip to the dealer. If you’re rebuilding a DMAX, you need this engine section open on your tablet.

Fuel, Emissions & Exhaust: DMAX Specific Part Numbers

Section 3 covers fuel, emissions and exhaust. The 2006 DMAX has a unique injection system and the catalog breaks down the fuel rail, injectors, and pressure regulator with their exact OEM numbers. Don’t trust a generic cross-reference for emissions components – they change by model year. This catalog gives you the right evap canister and EGR cooler part numbers for the 2006 application. Pair this with the AM General H1 1999-2000 Parts Catalog if you’re working on an earlier truck to avoid mixing revisions.

Cooling System Parts – Radiator, Hoses, and Gaskets

Cooling system section is 4 pages of radiator, fan clutch, water pump, and hose diagrams. The 2006 DMAX uses a specific thermostat housing gasket that aftermarket catalogs often list as a generic O-ring. Not here. You get the exact part number for the sealing washer. I’ve seen coolant leaks caused by a wrong gasket – don’t be that tech. Grab the correct part from this catalog and save a comeback.

Transmission and Transfer Case – Are Both Included?

Yes – section 5 covers both the transmission and transfer case. The 2006 DMAX uses the Allison 1000 series. You’ll find torque converter, valve body, and solenoid part numbers. The transfer case section lists chain, bearings, and shift motor components. For service procedures on these units, I’d recommend using the AM General Commercial Hummer 2002 Service Manual alongside this parts catalog. They complement each other.

Brake and Suspension Component Numbers

Brake system (section 7) gives you calipers, pads, rotors, and ABS modulator part numbers. Suspension section (section 9) covers axles, springs, and control arms. The 2006 DMAX has unique brake booster and master cylinder – the catalog lists them with supersession notes. For earlier models, the AM General HUMMER 1999 Service Manual covers the old brake system if you need reference.

Why the AM General DMAX 2006 Parts Catalog Is a Shop Bench Essential

Every time I see a guy order the wrong part because he trusted an aftermarket website, I want to throw a torque wrench at him. This catalog eliminates that. It’s a direct reproduction of AM General’s own parts listing – not a scanned copy of a copy. 647 pages, each with factory diagrams and part numbers that match what’s in the box. The General Information section at the beginning even covers VIN decoding and interchangeability notes.

Electrical Section: 13 Systems Mapped Out

Electrical section (page 12) covers 13 systems: battery, alternator, starter, wiring harnesses, sensors, switches, lighting, ECM, TCM, ABS controller, CTIS, HVAC control, and accessory circuits. Need the Automotive Battery hold-down bracket? It’s listed with the exact AM General number. The 2006 DMAX uses a specific battery cable routing that changed from 2005 – the catalog shows the updated part. This level of accuracy comes from OEM data, not guesswork. For an overview of how parts catalogs fit into the broader repair ecosystem, check the Automotive Industry Overview – but for this specific truck, nothing beats the factory print.

Frequently Asked Questions

Does this catalog cover aftermarket parts or only OEM?

Only OEM. Factory spec parts from AM General. No aftermarket substitutions.

How do I find a specific part number for the cooling system?

Flip to Section 4, page 4 in the PDF. The cooling system chapter lists each component with exploded diagrams and corresponding AM General part numbers. For example, the radiator assembly has multiple sub-parts – fan shroud, hoses, clamps. Matching the illustration to your truck’s VIN ensures you order the correct revision. I’ve seen guys grab a generic hose and then fight with fitment for an hour. This catalog gives you the exact number for the 2006 DMAX application. That kind of precision saves wasted trips to the dealer.
