twice a year (for instance, each spring or fall). You should let your GM
dealer's service department or other qualified service center do these jobs.

and steering system for damaged, loose or missing parts, signs of wear or
lack of lubrication. Inspect power steering lines and hoses for proper hook-up,
binding, leaks, cracks, chafing, etc. (On vehicles equipped with manual
steering gear, check for seal leakage.) Lubricate the steering linkage.

except the TBI throttle shaft. Do not lubricate the cam pulley. Remove all
external deposits from pulley. Do not oil any accelerator or cruise control
cables. Replace any cables that have high effort or excessive wear.

three-way catalytic converter. Inspect the body near the exhaust system. Look
for broken, damaged, missing or out-of-position parts, as well as open seams,
holes, loose connections or other conditions which could cause a heat buildup

compartments.

change intervals, check front axle and transfer case and add lubricant when
necessary. Oil the control lever pivot point (except L Van) and all exposed
control linkage. Check vent hose at transfer case for kinks and proper
