    What's the typical that you get done if and when you hit 100k for miles on your chevy? I've got two that are just about to 105k each, so I've got to get in and get this done.

    Plugs, wires? flush coolant? Tranny service? Other?

    I do a tranny service, plugs wires (if equipped) a new serp belt and toss the old on in a storage compartment. I also take a look at the throttle body to see how clean it and the IAC are.. Fuel filter. Depending on the coolant (i have a shop test it since i dont have the tool And i cant even think of the name) as long as shes good to go for -20degree F i call it good. But the newer DEX cool can have some build up. If you have aluminum heads a coolant flush isnt always a bad idea.

    Cost? I figured I can budget $750 or so for the Trailblazer.

    Want to spend less on the Cavalier as it's served its purpose as a commuter car and we're looking for another ride, but I'd like to keep it running and give it to charity or something as it's pry worth not a lot.

    You should replace the serpentine belt tensioner/pulley. It is recommended in the OEM service manual (at least for my 454 engine) to replace that tensioiner pulley each time the belt is replaced. But I just replaced it last summer when my '94 hit 83,000 miles.
