Gee thats funny cuz my 2003 S-10 only has 45 thousand on it and I've had all kinds of issues. Why the fuck is mine such a hassle? I do all the required routine stuff.
Well, haven't done anything extra special at all....maybe God Himself touched our Blazer.
This is what's been done with it...every oil change is with synthetic oil. Trans changed three times, each time (twice flushed) with synthetic. Rear end lube changed three times, again filled with synthetic.
On its third set of tires, counting the OEM Uniroyal Laredo set it came with. Each set has lasted almost 100K before getting to 2/32-3/32" left.
Front end alignments....have had a total of 5. Almost ready to quit doing this because outside the first one, the rest had little to no adjustments done to the front end. (My brother, and ASE cert'd. mechanic of almost 30 years experience, is the one doing the alignments on a Bear something-or-other alignment machine at his shop.)
Coolant changed every couple of years....
Air filters as needed....probably each year. Spark plugs last almost 100K as advertised by GM. But the truck hates anything being in it other than the AC Delcos it came with. I've tried a few other brands like NGK, but it hates them and starts to have misses, runs like junk if anything but AC Delco plugs are in it.
Same goes with the plug wires. AC Delcos are about the only brand that seems to work with it. Again, tried a few other brands over the years, but had to keep going back to Delco brand wires to get it to run smoothly without issues. Especially hate that because the Delco wires are the most expensive choice. (Honestly, I get nervous about plugs and wires lasting 100K, so I replaced the wires early the first time at 75K, but used crap Autolites and was repaid with worse performance vs. the old Delcos that were on it. Tried Bosch....junk again. Bought a performace set from Summitt. Worthless. No more of that....Delco only now.)
On its third set of shocks counting OEM. Third set of brakes, again counting OEM. Second set of front and rear rotors and calipers.
Oh, wait....did have an issue with the interior. The driver's back adjustment lever handle broke. Had to put a new one on....all of 30 sec. of work.
Oh yeah, I tow a lot with it. Have a 15" alu. boat with a 25hp Merc on the back. I know, small boat, but it gets us around. Also have two other trailers I take to auctions almost weekly...one open, one an enclosed Haulmark.
Maybe it's because of my age of 55 years, but that doesn't mean I drive like a bluehair. Even at my "advanced" age, I still manage to do around 80mph on the interstate.......and I love cruising Atlanta (75 in a 55 and no one looks at you), well, except at 5-7PM on weekdays.
