Figure 4–19 Check Engine Air Filter
a. Unhook the two retaining clips and remove the end cap (Item 4, Figure 4–19) from the air
cleaner housing (Item 1, Figure 4–19).
b. Pull the outer air cleaner element (Item 3, Figure 4–19) out of the housing.
c. After the main element is removed, check the condition of the inner element (Item 2,
Figure 4–19). It should be replaced whenever it appears dirty, typically every other time
the main element is replaced. Clean the area around the base of the inner element before
removing it, so dirt does not get into the engine.
d. Do not wash the paper element and inner element or use pressurized air, this will damage
the elements. Replace dirty, bent or damaged elements with new genuine Kohler elements
as required.
e. Handle new elements carefully; do not use if the sealing surfaces are bent or damaged.
f. Check all parts for wear, cracks, or damage.
g. Replace any damaged components.
h. If needed, install the new inner element, followed by the outer element. Slide each fully
into place in the air cleaner housing.
