TITLE: Timing Belt and Counter Balance Shaft Belt
APPLIES TO: 2.4L Optima
SERVICE TIP:
KMA recommends that the counter balance shaft belt/timing belt B be replaced when replacing the engine timing belt on 2.4L Optima vehicles, even
though this replacement is not specifically required per the maintenance section of the Optima Service Manual.
^
The counter balance shaft belt tensioner is a manual adjustment type. The belt should be inspected for looseness every time the enginetiming belt
is inspected. Recommended service intervals are as follows: under normal conditions, the engine-timing belt and counter balance shaft belt should
be inspected every 30,000 miles and replaced every 60,000 miles.
^
Under severe conditions the engine-timing belt and counter balance shaft belt should be inspected every 20,000 miles and replaced every 40,000
miles.
For further instruction regarding the inspection, removal and installation of the timing belt, and the counter balance shaft belt/timing belt B, see the
Optima Service Manual or KSIS.
