1992 GMC K2500 Suburban Service and Repair Manual
This factory service and repair manual for the 1992 GMC K2500 Suburban pairs two gasoline V8s, the 7.4L and the 5.7L, both naturally aspirated and overhead-valve, with a single four-door sport utility body and just two trims, Base and SLE.

Known issues on the 1992 K2500 Suburban. Three recalls appear on the federal record. Replacement fuel filters sold for these trucks may not seal at the joint, so fuel can leak and find an ignition source; replacement oil filters can seal just as badly and let the engine shed its oil; and unexpected heat in the automatic transmission can push fluid out of the vent tube, where it can ignite. One owner complaint, about visibility, is logged with NHTSA. Fuel and transmission procedures, torque values and wiring diagrams cover the systems those entries name.
