Has been a really good vehicle. Had it now for about 2 years and only put about 3k miles on it, from the odometer pic you see. I was warned that the water pumps did not last. It was leaking when we looked at it. I worked a new water pump price in to the deal we made. I put a new water pump and fan clutch on it and a thermostat. New fuel filter and fuel pressure regulator. Had a leak at the regulator. Fuel pressure tested and is good. She was gonna drive up to her property in Wa. for a weekend and the CEL came on about 25 miles out of town. Was running fine. I told her to turn around and she ended up taking her recently sold 1990 K2500 Light Duty 3/4 ton 4x4 ext cab truck instead. Had the code problem fixed that afternoon. VVT solenoid. A/C blows cold and all of the drive selections work as should. Nothing but full Mobil 1 synthetic oil changes with WIX filters. When we got it I did all fluids: Both diffs, transfer case, transmission and filter, coolant done with water pump, power steering fluid and brake fluid. Never been wrecked. No rust. Has been in PNW it's whole life. Almost forgot: New AC Delco spark plugs and a new ignition switch that showed intermittent signs of a well known switch problems of turn key and no crank. If cycled again, would start. I put the updated Genuine GM switch in it. There are videos at you tube for the plugs and switch replacements.
I like driving it and am comfortable in it. That 4.2 straight 6 is a great power plant with the 4L60E transmission. I even replaced the rear cargo roll out curtain with the correct color replacement. I have to see which vehicle she wants to drive daily. The TrailBlazer or the 2005 Tahoe Z71.
I will say this: It is a very base LS model. So base that it came from factory without a key fob capability. Can be added but we never did.
Again, almost forgot, about 1.5 years ago: New Interstate AGM battery.
