CORROSION PREVENTION AND SEALING
77-4-6 CORROSION PREVENTION
Corrosion prevention
Factory treatments
During production, vehicle bodies are treated with the following anti-corrosion materials:
lA PVC-based underbody sealer which is sprayed onto the underside of the main floor, rear floor, front and rear
wheelarches and the front valance assembly;
lAn application of cavity wax which is sprayed into the sill panels, 'A' post, 'B-C' post, fuel filler aperture, body rear
panel and the lower areas of the door panels;
lA coating of underbody wax which is applied to the entire underbody inboard of the sill vertical flanges, and
covers all moving and flexible components EXCEPT for wheels, tyres, brakes and exhaust;
lA coat of protective wax applied to the engine bay area.
Whenever body repairs are carried out, ensure the anti-corrosion materials in the affected area are repaired or
renewed as necessary using the approved materials.

+ BODY SEALING MATERIALS, MATERIALS AND APPLICATIONS, Approved materials.
Precautions during body repairs and handling
Take care when handling the vehicle in the workshop. Underbody sealers, seam sealers, underbody wax and body
panels may be damaged if the vehicle is carelessly lifted.

+ LIFTING AND TOWING, LIFTING.
Proprietary anti-corrosion treatments
The application of proprietary anti-corrosion treatments, in addition to the factory-applied treatment, could invalidate
the Corrosion Warranty and should be discouraged. This does not apply to Rover approved, compatible, preservative
waxes which may be applied on top of existing coatings.
Fitting approved accessories
When fitting accessories ensure that the vehicle's corrosion protection is not affected, either by breaking the protective
coating or by introducing a moisture trap.
Do not screw self-tapping screws directly into body panels. Fit suitable plastic inserts to the panel beforehand. Always
ensure that the edges of holes drilled into panels, chassis members and other body parts are protected with a suitable
zinc rich or acid etch primer, and follow with a protective wax coating brushed onto the surrounding area.
Do not attach painted metal surfaces of any accessory directly to the vehicle's bodywork unless suitably protected.
Where metal faces are bolted together always interpose a suitable interface material such as weldable zinc rich
primer, extruded strip, or zinc tape.
Steam cleaning and dewaxing
Due to the high temperatures generated by steam cleaning equipment, there is a risk that certain trim components
could be damaged and some adhesives and corrosion prevention materials softened or liquified.
Adjust the equipment so that the nozzle temperature does not exceed 90
° C (194° F). Take care not to allow the steam
jet to dwell on one area, and keep the nozzle at least 300 mm (11.811 in) from panel surfaces.
DO NOT remove wax or lacquer from underbody or underbonnet areas during repairs. Should it be necessary to
steam clean these areas, apply a new coating of wax or underbody protection as soon as possible.
Inspections during maintenance servicing
It is a requirement of the Corrosion Warranty that the vehicle body is checked for corrosion by an authorised Land
Rover Dealer at least once a year, to ensure that the factory-applied protection remains effective.
Service Job Sheets include the following operations to check bodywork for corrosion:
lWith the vehicle on a lift, carry out visual check of underbody sealer for damage;
lWith the vehicle lowered, inspect exterior paintwork for damage and body panels for corrosion.
It will be necessary for the vehicle to be washed by the Dealer prior to inspection of bodywork if the customer has
offered the vehicle in a dirty condition.

HEATING AND VENTILATION
DESCRIPTION AND OPERATION 80-9
FBH fuel pump
The FBH fuel pump regulates the fuel supply to the FBH unit. The FBH fuel pump is installed in a rubber mounting on
the chassis crossmember immediately in front of the fuel tank. The pump is a self priming, solenoid operated plunger
pump, with a fixed displacement of 0.063 ml/Hz. The ECU in the FBH unit outputs a pulse width modulated signal to
control the operation of the pump. When the pump is de-energised, it provides a positive shut-off of the fuel supply to
the FBH unit.

10Non return valve
The solenoid coil of the FBH fuel pump is installed around a housing which contains a plunger and piston. The piston
locates in a bush, and a spring is installed on the piston between the bush and the plunger. A filter insert and a fuel
line connector are installed in the inlet end of the housing. A non return valve and a fuel line connector are installed
in the fuel outlet end of the housing.
While the solenoid coil is de-energised, the spring holds the piston and plunger in the 'closed' position at the inlet end
of the housing. An 'O' ring seal on the plunger provides a fuel tight seal between the plunger and the filter insert,
preventing any flow through the pump. When the solenoid coil is energised, the piston and plunger move towards the
outlet end of the housing, until the plunger contacts the bush, and draw fuel in through the inlet connection and filter.
The initial movement of the piston also closes transverse drillings in the bush and isolates the pumping chamber at
the outlet end of the housing. Subsequent movement of the piston then forces fuel from the pumping chamber through
the non return valve and into the line to the FBH unit. When the solenoid coil de-energises, the spring moves the piston
and plunger back towards the closed position. As the piston and plunger move towards the closed position, fuel flows
passed the plunger and through the annular gaps and transverse holes in the bush to replenish the pumping chamber.
