G.M. Evaporation
Control SYltem
The Evaporation Control System
requires only periodic canister filter
servicing.
Every 12 months
or 12,000
miles, whichever occurs first, (more
often under dusty conditions) the
filter in the base of the canister
must be replaced and the canister
inspected.
Drive Beltl
Every 6,000 miles or 4 months
inspect drive belts for wear, fray
ing, cracking, and tension. Belts
which are in poor condition should
be replaced immediately.
Check tension by applying
mod
erate thumb pressure midway be
tween pUlleys. If the center-to
center distance between pulleys
is
13 to 16 inches, the belt should
deflect
lh inch. If the center-to
center distance
is 7 to 10 inches,
the belt should deflect
1;4 inch.
Loose belts should be retensioned
to give the correct deflection.
