fter loosening) using a 3/8"
square drive 13 mm socket, ex tensions and U.J as shown.
1. Installation is the reverse of the removal procedure. Tighten
the starter motor securing bolts to 38-48 Nm.
2. Refit the steering rack as detail ed in Operation 57.10.01. Refill
the reservoir with the reco mmended fluid and bleed the
steering system.
3. Lower the ramp. Remove the protection sheets and close the

harge Air Cooler System
Each cyl
inder bank is fitted with a charge air cooler unit wh
ich supplies pressurized air to the four cylinders via an adaptor
block. The inlet ports to the tw o charge air coolers are connected to the supercharger outlet by an inle t assembly consisting
of rubber ducts and clamp plates . An outlet stub at the rear of each charge air cooler unit provides the connection for the
by-pass valve airflow. The charge air coolers ar e water cooled via a radiator and coolant pump.
Charge Air Cooler Coolant System
Parts List
Each charge air cooler unit is a fin and tube air to liquid heat exchanger. The coolant circuit for the charge air coolers
consists of a pump, ra diator, connecting hoses and a bleed pipe.

The OR
VR system features are :
N
arrow fuel filler pipe and tank check valve.
Fue
l level vent valve (FLVV) fitted to the evaporative flan
ge and consisting of a two stage shut-off valve with rollover
protection and a pressure relief valve.
Grade ven
t valve with rollover protection, fitted to the ev
aporative flange and with an outlet pipe connected to the
FLVV vapour outlet pipe.
Large bore vapour vent pipes.
The fuel filler pipe has a reduced diameter between the nozzle guide and the tank, providing a liquid seal when re-fueling
and preventing the fuel vapour venting directly to atmosphere. There is no breather tube fitted between the tank and the
filler nozzle. To prevent spit back when re-fueling, a check valv e is fitted at the lower end of the filler pipe inside the tank
(see Figure).
During re-fueling, the tank is vented to atmosphere via the fuel level vent valv e (FLVV), large bore vapour pipes and the
charcoal canisters. The FLVV incorp orates a float valve which is closed by the rising fuel level, creating a back pressure and
causing the fuel delivery to stop. In the closed position, the FLVV also sets the fuel level.
With the FLVV closed (tank full), any increase in pressure or overfilling is relieved by a separate rollover protected grade
vent valve. The outlet from this valve feeds into the main FLVV vapour outlet pipe, bypassing the closed FLVV.
When the fuel level is below full, the FLVV opens to allow unrestricted venting via the canisters.
A pressure relief valve is incorp orated into the FLVV assembly and has an outlet pipe to the filler nozzle,. If a blockage or
other restriction (eg, canister close valve failing in the closed position) occurs in the vapour vent system, the pressure reli ef
valve opens to allow venting to atmosphere via the filler nozzle guide and fuel filler cap.
Canister purge operation is as described in Evaporative Emissions Control.
Filler Tube and Check Valve
Page 1158 of 2490
The fuel fil
ler cap is the same as
that used on non-ORVR systems.
The check valve assembly is a push fit into the end of the fuel filler tube and is accessible with the evaporative flange
removed. The valve has a light spring load ing and opens under the inflow of fuel.
ORVR Evaporative Loss Flange Assembly
The evaporative loss flange assembly is fitted to the top of the tank via a seal and locking ring arrangement identical to that
used for non-ORVR systems. The assembly is re moveable complete with the fitted components.
The fuel level vent valve (FLVV) is mounted in the ELF assembly via a bayonet fitting : it is turned approximately 90 °
clockwise to release. The grade vent valve and pressure sensor are push in fits via sealing gromme ts : note that, due to the
tight fit, removal of these components may require cutting the grommets. The fuel pump connector is push fitted and
crimped into a location tube on the underside of the flange.
