3.2 Engine Cooling
3.2.1 Auxiliary Heater Systems
WARNINGS:
Ford coolant additives are
necessary for the complete function
of the system. Only use ford
approved or equivalent specification
component, to withstand any
detrimental effects on the materials.
Do not mount components in front
of the grille or in an area of air flow
around the engine, which could
affect the engine cooling.
CAUTIONS:
Only make connections into the
heater hose between the front cab
heater and water pump return inlet.
Do not exceed the vehicle's original
coolant volume by more than 10%
Only use the manufactures
recommended (or equivalent
specification) coolant
additives/anti-freeze. Do not mix
coolant types.
•Coolant flow to cab heater must have priority
over flow to auxiliary heater or hand wash
facility.
•Coolant tube routing must be below the base
of the degas bottle.
•Use aluminum or plastic tee junction with
swaged or beaded ends to prevent hose blow
off. Reconnect original coolant tube as shown
in view E74570 (in this section) with standard
Ford water hose clip or suitable equivalent
specification clip. Ensure interference fit
between hose and 'T' joint.
•Tube routing must be secured to the body
structure or suitable brackets avoiding
electrical components or wires, hot or moving
parts and brake or fuel system components
•Hose must be heat sleeved with appropriate
material if within 100mm of exhaust
components (for example, manifold or
exhaust gas recirculating).
•The vertical clearance between the critical
cooling components (radiator, fan shroud and
radiator brackets) and both the hood inner
and outer (assembly) panels at design position
shall not be less than 15mm.
•There shall be a minimum clearance of 7mm
between the engine assembly and flexible
components (for example, hoses or wiring
harnesses) affixed to front end sheet metal
hardware, under a maximum engine torque
roll condition.
NOTE: For further information please contact
your local National Sales Company
representative, or Local Ford Dealer. If they are

4.14.1 Vehicle Speed Output
(Signal)
At present, this information is only readily available
as a CAN message. However, on Diesel vehicles
it is possible to access a hard-wired output.
In the engine compartment there are three
connectors on the left hand side (viewed from
driving direction). On left hand drive vehicles, the
three connectors are covered with a plastic
shield that can be easily disassembled. On right
hand drive vehicles there is a special metal
security shield fixed with a shear bolt (part
number 6M5Y-12B539-A*). The vehicle speed
signal is available on pin K1 of the middle (brown)
connector, C2 – see Figure E84720 (Additional
Vehicle Signal / Features). This provides a square
wave-form (50% duty cycle) signal, where a
frequency of 138Hz equates to 100km/h.
Note:-
•A hard-wired vehicle speed signal is only
available on diesel engine vehicles.
•Vehicle speed is derived from one of two
sources, the wheel speed sensor (for vehicles
with ABS etc.) or the vehicle speed signal – in
both cases, these are un-calibrated signals.
According to transmission, drive-line and other
vehicle parameters that are set, the
Powertrain Control Module generates a CAN
message of vehicle speed for all vehicle types.
There is No hard-wired vehicle speed signal
on gasoline (petrol) vehicles.
•There is No automated shift transmission for
V4347/8 (there are no plans to introduce this
later in the program).
•VMT6 transmissions will not support fitment
of a vehicle speed sensor.
Connector Position for Vehicle Speed Signal in the Engine Compartment
In order to avoid electrical issues due to leakage,
and to ensure connector compatibility, a
pre-crimped wire and terminal, available as part
of a wiring accessory kit, should be used (kit part
number KT6C1V-14A411-J*). For further
information see 'Adding Connectors, Terminals
and Wiring' in this manual.
