Known issues on the 1986 G10. The one recall on this van's federal record was raised against replacement oil filters offered for it, which could seal badly enough to let the engine pump its oil out and start a fire. One owner complaint is also recorded, this one about steering. The manual covers both ends of that: lubrication service with oil pressure specifications and filter and pump procedures, and a steering section giving gear and linkage service, play and alignment figures and the torque values for the parts that hold it together.
