The GM light-truck 6.2L and 6.5L diesel engines were optional in the 1982-2000 C/K series pickup trucks, and in the Suburban, Chevy Tahoe & Blazer, GMC Yukon & Jimmy, vans, and motor homes (RV) - in both turbo diesel (TD) and naturally aspirated (NA) versions. In addition, low cost and ready availability have made these engines extremely popular the world over for diesel conversion projects; powering Land Rovers, Land Cruisers, and a host of other foreign and domestic production vehicles.
Designed as a diesel engine from the ground up by the Detroit Diesel Division of General Motors, the original 6.2L diesel engine was introduced in the 1982 model year GMC and Chevy C/K pickup truck and full-size SUV lines. Taking this engine design to the next level in the 1992 model year, the new 6.5L diesel engine was an advancement in technology, and was designed for the application of a turbocharger. The 6.2L saw its final year of production in 1993. While the 6.5 was replaced by the Duramax 6600 beginning in the 2001 model year Chevy and GMC vehicle production, the 6.5L diesel engine continues to be manufactured and sold by AM General. AM General is the manufacturer of the civilian H1 Hummer & military HMMWV. Not to worry, support for the 6.2/6.5 will continue to be a big part of The Diesel Page well into the future.
The Diesel Page has expanded coverage of GM's diesel engines since the introduction of the Duramax 6600, which is a result of a joint venture between Isuzu and the General Motors Corporation (forming DMAX Ltd.). We'll have all of the latest test reports and event coverage as that information becomes available for the LB7 / LLY / LBZ / LLM / LMM Duramax 6600 diesel engines, as well as Allison 1000 series 5-speed & 6-speed automatic transmissions. Our professionally written product coverage and bulletin board discussion forum will have the latest information concerning the LB7, LLY, LBZ, & LMM Duramax diesel engines, as well as product reviews covering electronic upgrades such as chips, tuners, and programmers.
