2003 GMC Sierra 2500 Service and Repair Manual
Regular price
$29.99 USD
Unit price
This factory service and repair manual for the 2003 GMC Sierra 2500 has four trims to answer to, Base, SLE, SLT and WT, from bare work truck to loaded. One engine sits under all of them, the naturally aspirated 6.0L overhead-valve gasoline V8 of 364 cubic inches, in either a 2-door standard cab pickup or a 4-door extended cab pickup. Procedures, specifications, torque values, wiring diagrams and diagnostics follow the systems rather than the trim, so a WT and an SLT are serviced the same way.

Known issues on the 2003 Sierra 2500. Eight recalls are on the federal record. One concerns trucks built without a continuous urethane bead behind the windshield, so the glass may not stay put in a crash. Another concerns a hydro-boost housing relief valve bore machined out of specification, letting the valve seal fracture and raising pedal and steering effort. A third concerns second-row center lap belt routing that rides high on the abdomen instead of the hips. Owners logged 573 complaints, 249 of them on service brakes, then the electrical system and steering. Brake, body glass and restraint procedures all appear here.
