Fan Clutch; General Controls - Haldex RF5910XX Manual De Instalación

GENERAL CONTROLS INSTALLATION
The Bendix-Style Fan Clutch is controlled by air pressure and is
spring engaged and air released. Consequently, the control system
must allow the Fan Cutch to engage on rising temperature of the
engine coolant.
The air supply for the controls should come from a protected source
which is available on most vehicles, but if not, the air supply should
be routed through a pressure protection valve such as HVSG
286500 (85 psi) as shown on Fig. 15. Tubing or hose at least 3/16"
I.D. should be used. Wiring for electrical controls should be minimum
14 gauge.

BHVSG recommends thermo-pneumatic controls for the basic
control system and electro-pneumatic components as required, to
interface with air conditioning systems. Four basic configurations
may be encountered:
A. Vehicle with no shutters and no radiator mounted air conditioning
condenser. (See Fig. 16).
B. Vehicles with shutters–no air conditioner condenser. (See Fig. 17).
C. Vehicles with no shutters–with air conditioner condenser. (See Fig. 18).
D. Vehicles with shutters and with air conditioner condenser. (See Fig. 19).
Thermo-pneumatic Controls must be installed in appropriate ports in
the engine water jacket preferably near a water discharge port (see
Fig. 20 for P/N identification). The fan control setting should be at
least 10°F higher than the engine thermostat fully open position. It is
recommended a new Engine Thermostat be installed at the time the
Fan Clutch is installed. If Shutters are included in the installation, the
Fan Control Valve should be installed as close as possible to and at
least 10° higher than the Shutter Control Valve.
