Hood Inlet Seal
If the vehicle is being used in heavy snow conditions or
for snow plowing, there is a possibility of snow and
ice build up in the inlet to the air cleaner, which
can block airflow to the engine and affect impacting
engine performance.
To prevent this from happening, remove the hood
inlet seal:
1. Loosen the clamp that holds the seal to the air
cleaner.
2. Slide the seal off.
3. Store the seal in the inlet, located on the underside
of the hood.
4. Store the air cleaner clamp on the coolant surge
tank. Pull the overflow tube out of the white plastic
retainer, slip the clamp over and reinstall the hose.
Replace the air cleaner seal during non-snow or non-icy
conditions.
