My 05 ZR2 has 200k miles now. Just got done replacing the whole cooling system and rebuild of the steering and suspension. Rebuilt trans at 160k, but other than that it runs great.
Even though this forum is for the new 2021 Trailblazer I'm sure nobody will care if you hang around.
Nice, My rig is at 222,471 Miles, i put 166 of them on it just doing laps around my neighborhoods private roads after getting it running.
Had motor/trans swap before i owned it, tranny had the pan put back on it and the motor threw a timing chain, where i come in was offering to buy it off my father as i didnt want him to scrap it, he made a bet if i made it run the title was mine, one of many memories i have tied to this rig. Had to put: Ignition switch fuel pump distrubtor cap/rotor/wires/plugs, upper intake seals kit, vacuum lines, Crank sensor, Timing cover and Chain/gear set/oil change (times 3 to flush out gunk) marvel oil the entire motor top to bottom inside to clear out any possible rust or water even though it was in a garage there was a tiny bit.
oh and Catylitic converter/muffler. walker/dynomax all the wayyy. but now, it runs like new, the drivetrain is so jarringly cleaner feeling then the rest of the trucks driving characteristics would make you think.
