Listed below are inspections and services which should be perfo\
rmed at
least twice a year (for instance, each spring and fall). You should let your
GM dealer’s service department or other qualified service center do these
jobs. Make sure any necessary repairs are completed at once.

except the
TBI throttle shaft. Do not lubricate the cam pulley. Remove all
external deposits from pulley.

cables. Replace any cables that have high effort or excessive \
wear.

body near the exhaust system. Look for broken, damaged, missing or
out-of-position parts, as well as open seams, holes, loose conn\
ections or
other conditions which could cause a heat buildup
in the floor pan or could
let exhaust fumes seep into the passenger compartments. See “\
Engine
