ya, but i believe this is a reverse-flush type of deal, not including auto filter/pan gasket change...
******d/l that FSM for the 89-90 that a member has on his server before it closes down again!!! <if u don't have it already>******
for the heck of it, see if there are any trouble codes stored in the ECU b4 goin' ahead
plan in stages-- cheap n easy to shop...
before changing these things out <<<change pcv valve (oem)o2 sensor (ngk)spark plugs (ngk)>>>
consider seafoamin' your engine, then oil change & proceed...
w/ coolant flush, i'd drain radiator, drain block, flush w/ a chemical, then drain, flush w/ water, drain, flush w/ distilled water, drain, fill w/ 50:50 coolant:distilled water mix <i used orange/GM dexcool> n changed over hoses & belts @ the same time... throw in a new rad cap n t-stat.
good to bleed brakes of old fluid < i like valvoline synthetic dot3/4> but since you're planning an upgrade, this can wait...
definitely change your diff fluid w/ mobil synthetic 80W90...
there's alot more & it can become a $pit
