Indirect Injection Diesel (IDI) V8 engines were produced by Detroit Diesel under the GM umbrella from 1982 to 2000. IDIs were more fuel-efficient compared to the big block 454ci gas engines you would find in Ford and Dodge trucks of that era. The 6.2L and then 6.5L IDI turbo diesels were similar to the Chevy gas powered small block engines found in pickups of the time in that they used the same 90 degree V8 GM bellhousing pattern. +Read more
Fortunately, they were heavily produced by GM and later by General Engine Products (a subsidiary of AM General), so if you’re on the hunt for 6.2 or 6.5 diesel parts, you should have no trouble tracking them down including right here on ProSource Diesel.
6.2 and 6.5 diesel engines can be found in full-size GM pickups, SUVs, vans and some motor homes made between 1982 and 2000. Vehicles using the 6.2 and 6.5 IDI include the Chevy C/K pickup, Suburban, the K5 Blazer and its replacement the Chevy Tahoe.
The 6.2 and 6.5 IDI shared some common problems. The main bearing often developed web cracks plus, there were often failures of the harmonic balancer, drive pulley or the dual mass flywheel. Other common problems included a failed pump mounted driver, cracked cylinder head or oil cooler line failure.
