2000 Chevrolet Astro

Engine Performance problem
2000 Chevy Astro 6 cyl Two Wheel Drive Automatic 100000 miles

Taking the van on long trip and would like to replace
things that might go bad on the trip like the timing
and fan belt. Would like to do a full tune up that you would recomend and gas filter. What parts on the tune up would you recomend. Would it be good to run some kind of fule cleaner in the gas also.
Thank You

Hi: A general tune up iincludes plugs, wires, cap, rotor, and fuel and air filter. However, a very wise mechanic, who was my teacher, always said if it's not broken, don't fix it. The 4.3L V6 is a great engine and if it's running good, you may want to leave well enough alone.

Let me know what you think.
