Operation 3
Check the Fan/Water Pump Belt Tension
The engine fan and water pump share the same drive
belt (2) . A self adjusting spring-loaded idler () keeps
a constant tension on the belt . If the belt is found to
be loose, check the pivot of the spring-loaded idler for
binding . If the spring-loaded idler is operating fine,
belt replacement maybe necessary .
If the belt requires replacement, install a square end
of a 9 mm (3/4") breaker bar into the slot of the idler
and release the spring tension by pushing down on the
wrench . Slip the old belt off the engine pulleys and
install a new belt . Release the wrench and allow the
spring-loaded idler to apply belt tension .
