Steps
Disconnect the battery and open access
Disconnect the negative battery cable. Remove the air collector retainers and duct, then unplug the fan shroud connectors and remove its fastener.
Remove the fan and shroud
Use the fan clutch wrench to loosen the reverse-threaded fan clutch, turning it in the correct direction. Lift the fan and shroud out together without damaging the radiator.
Remove the exhaust cam sensor
Unplug the exhaust camshaft sensor connector and remove its 5 mm hex retaining screw. Carefully withdraw the sensor from its bore.
Install the replacement sensor
Lightly oil the new sensor's O-ring, seat the sensor squarely in its bore, and install the retaining screw. Reconnect the electrical connector.
Reinstall the fan and reconnect the battery
Lower the fan and shroud into place, reinstall the shroud fasteners and connectors, then secure the fan clutch to specification. Refit the air collector and reconnect the negative battery cable.
Check your vehicle’s repair manual for exact specifications and fit.
