250k miles. Engines will run forever but trannies go out around 180k, and then there's just piddly stuff.
I have a 1999 with 200,000 miles on it and still running strong.
I have a 1999 blazer. The heater core clogs up about once a year from the Dexcool. Try having it (heater core) flushed and use Prestone (Extended life) instead of Texaco.
Our 1999 Chevy Lumina car - 3.1L at 150k miles has been very reliable, to date replaced alternator, reg tune up items (belt, hoses, ect...) and brakes.
The life expectancy of a vehicle, regardless of its model, depends on the owner. On how it is maintained and used.
The Blazer was a decent vehicle which had its quirks. The rear seal on the Chevy small blocks are notorious for needing replacement, as is the intake manifold gasket. Body wise, the actuator arm for the rear glass is prone to breaking, and will need replacement at some point in the vehicle's service life.
130000 and drives like the day i bought
The life expectancy of a timing chain on a 1999 454 Vortec engine is 5 to 10 years. The exact time depends on how often the vehicle is driven.
about three hundred thousand miles. if properly maintained.
My guess would be between 100K and 150K on average.
175,000 miles before major repairs.
What was life expectancy in
I've got 171k and still running like a champion
