2003 GMC Safari Service and Repair Manual

This factory service and repair manual for the 2003 GMC Safari returns a Base model to the lineup alongside SLE and SLT, on the three-door extended cargo van and the three-door extended passenger van. The engine remains a single gasoline unit, the 262-cubic-inch 4.3L V6 with overhead valves and natural aspiration. Front suspension and steering work figures heavily on a van of this age, and the ball joint, control arm and linkage procedures come with the specifications, torque values, wiring diagrams and diagnostics for the rest of the vehicle.

Known issues on the 2003 Safari. Three recalls are on the federal record. The most serious is an interference between the lower ball joint boot and the steering knuckle: the boot can be cut, the joint loses its seal, and the knuckle can eventually separate from the lower control arm and drop that corner of the van onto the road. The others involve replacement fuel filters that may leak at their connection and replacement lamps missing amber side reflectors. Owner complaints total 27, led by 12 on the service brakes with two each on the air bags and the engine and cooling system.
