3.7.2 Air Cleaner Restrictor Indicator (if
equipped)
The air cleaner restriction gauge mounted on the air
cleaner(s) helps determine the air cleaner change
interval.
The air cleaner restriction gauge monitors air flow and
continuously displays restriction readings indicated as
vacuum (see Figure 3-10). Increased restriction
indicates a clogged air cleaner element.
As maximum allowable restriction is reached, the gauge
window turns red indicating the air cleaner element
needs replacement. To reset the gauge, push the gauge
top down and release.
