Hey dudes, I am getting a 1985 k5 with the 6.2 in it and was wondering what the 1st thing i should do would be? I know on a gas engine i would just do a tuneup with plugs and rotor type stuff, but what should i do on a Diesel? The guy i am buying it from said the glow plugs are good and it started up as soon as i turned the key. I figured i would change the filters and all the fluids. The odometer says it has 93,000 miles but there is no place for the 100,000 digit, should i just pull the motor and rebuild it? Because then it would be fresh and i wouldnt have to worry about anything. I would still have another vehicle so it wouldnt have to happen fast. And also it needs a new instrument cluster, or thats what i was told, the speedo doesnt work (could need a new line or new gear in the tranny) and i think it was the temp gauge missing a needle. After i get it home i will figure out what else doesnt work. Is there a site that would have an aftermarket kit for it? I think it would be cool to have white gauges in there. Anyways thanks a lot guys.
