Known issues on the 1987 G30. No recalls and no owner complaints stand against this model year on the federal record. Read the manual, then, as a service reference rather than a fault list: it sets out engine mechanical and cooling procedures for the V6, the gasoline V8 and the diesel, fuel delivery and ignition diagnostics, transmission and rear axle work, brake and steering specifications with their torque figures, and body electrical wiring diagrams for each of the six body configurations this year was built in.
FUEL TANK LOWER FILLER PIPE MAY CONTAIN SMALL HOLES AT SOME SPOT WELDS USED TO ATTACH A MOUNTING BRACKET.
