ISSUE:
The A/C system may shut off due to high system pressures and/or there may be a lack of cooling at an idle. This may be caused by insufficient air flow
being provided by the fan clutch. The fan clutch has too low of an idle rpm.
ACTION:
Verify the fan clutch is the cause of the concern and, if necessary, replace the fan clutch. The new fan clutch will have a higher idle rpm. Refer to the
following Service Procedure for details.
SERVICE PROCEDURE
1.
Apply reflective tape to one (1) fan blade.
2.
Run engine at 3000 RPMs until fan clutch disengages, which should occur within 60 seconds.
3.
Let engine return to an idle for 2 minutes.
4.
Measure the fan speed at 2 minutes and again at 10 minutes using a Newark Electronics 6611 Series (or equivalent) tachometer by pointing the
probe at the fan blades a distance of 6-12" (15.2-30.5 cm) from the fan blades.
5.
If the fan speed is below 500 RPMs, replace the fan clutch with a new fan clutch (F5TZ-8A616-KB). If the fan speed is above 500 RPMs, refer to
the appropriate Service Manual for proper diagnostic procedures.
