Temperature Sensor

1. Disconnect the negative battery cable!
Locate the temperature sensor on the air intake
tube. Slide the red tab, squeeze the black tab on the
electrical connector, and then disconnect the tem­perature sensor wiring harness. Now carefully,
remove the sensor from the tube using a slow cir­cular motion. Save the sensor for reinstallation
later. Disconnect the crankcase breather tube from
the air filter box. Loosen one hose clamp at each
end of the air intake tube and remove it from the
vehicle.

2. Lift up the front of the engine beauty cover, and
then pull it towards you to remove it from the vehi­cle. It is only held in position by rubber grommets.

3. Using a 13mm socket, remove the two bolts that
hold the air cleaner mount to the inside right fend­er. Save them for reinstallation in step #10.

4. Rock the airbox back and forth as you are lift­ing it straight up to remove it from the vehicle. It is
