So I'm getting ready to potentially sell my '99 Silverado 1500 and while I've been slowly replacing things along the way of owning it, at 186K miles it's starting to accumulate little problems. It's a regular cab longbed so the dealer I took it to for a ballpark trade in already doesn't really want to touch it real bad since it's a regular cab.
It's had the mystery disappearing coolant for awhile now but after my most recent fill it's been pissing on the driveway pretty bad. I'm 95% sure its the water pump gaskets but again at 186K miles, should I just replace the pump even though I'm selling it?
Same deal with the ABS, intermittent fault on the drivers front sensor, I've tried cleaning the connectors and it doesn't look caked with debris. Replace?
To get out of the specifics, how about turning the question around. What would you be looking for to work on a high mileage truck like mine?
