1985 Chevrolet G30 Service and Repair Manual

Four naturally aspirated overhead-valve engines are covered: a 4.3L V6 of 262 cubic inches, a 5.0L V8 of 305, a 5.7L V8 of 350 and a 6.2L diesel V8 of 379.

Known issues on the 1985 G30. Nothing sits on the federal record for this year: no recalls and no owner complaints. That leaves the manual as the reference for everything routine and everything awkward, engine mechanical work across the V6, both gasoline V8s and the diesel; fuel and ignition diagnostics; transmission and driveline service; axle, brake, steering and suspension specifications with their torque values; and wiring diagrams covering six bodies whose electrical routing is not identical from one to the next.
LEFT HAND LOWER CONTROL ARM CAN CRACK AND COULD EVENTUALLY CAUSE THE LOWER BALL JOINT TO SEPARATE FROM THE CONTROL ARM.
LOSS OF STEERING CONTROL CAN OCCUR WHICH COULD RESULT INA CRASH WITHOUT PRIOR WARNING.
