This factory service and repair manual for the 2002 Chevrolet G30 belongs to a working vehicle stripped to essentials: one body, a three-door standard cargo van; one trim, Base; one engine, the naturally aspirated overhead-valve 4.3L V6 of 262 cubic inches. Because the range does not branch, the specifications, torque values, wiring diagrams and diagnostics in it describe exactly one vehicle, and no cross-checking against other engines or equipment levels is needed before a job begins.
Engines covered
- 4.3L V6 (262 cu in) — OHV, naturally aspirated, gasoline
Body styles covered
- 3-door standard cargo van
Trims covered

Known issues on the 2002 G30. One owner complaint is on record for this model year, against engine and engine cooling. That is thin evidence of anything, but the cooling system on a van that idles and hauls is worth knowing well, and it is documented here: thermostat and coolant specifications, water pump and radiator procedures, fan and belt drive service, pressure and leak testing, and the diagnostic charts for an overheating engine. The same depth applies to the engine mechanical, fuel, transmission, brake, steering and body electrical sections.
This PI communicates the requirement to provide a pico file to receive diagnostic assistance from TAC.
