Steam Cleaning and Dewaxing

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 degrees C (194 degrees F). Take care not to allow the steam jet to dwell on one area, and keep the nozzle at least 300mm 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:
^ With the vehicle on a lift, carry out visual check of underbody sealer for damage.
^ With the vehicle lowered, inspect exterior paintwork for damage and body panels for corrosion.

The vehicle must be washed and free from deposits prior to inspection. It is part of the owner's responsibility to ensure that the vehicle is kept free of accumulations of mud which could accelerate the onset of 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. Particular attention should be paid to areas where access is difficult.

The checks described above are intended to be visual only. It is not intended that the operator should remove trim panels, finishers, rubbing strips or sound-deadening materials when checking the vehicle for corrosion and paint damage.

With the vehicle on a lift, and using an inspection or spot lamp, visually check for the following:
^ Corrosion damage and damaged paintwork, condition of underbody sealer on front and rear lower panels, sills and wheel arches.
^ Damage to underbody sealer. Corrosion in areas adjacent to suspension mountings and fuel tank fixings.

The presence of small blisters in underbody sealer is acceptable, providing they do not expose bare metal.

Pay special attention to signs of damage caused to panels or corrosion protection material by incorrect jack positioning.

CAUTION: It is essential to follow the correct jacking and lifting procedures.

With the vehicle lowered, visually check for evidence of damage and corrosion on all visible painted areas, in particular the following:
^ Front edge of bonnet.
^ Visible flanges in engine compartment.
^ Lower body and door panels.

Rectify any bodywork damage or evidence of corrosion found during inspection as soon as is practicable, both to minimise the extent of the damage and to ensure the long term effectiveness of the factory-applied corrosion prevention treatment. Where the cost of rectification work is the owner's responsibility, the Dealer must advise the owner and endorse the relevant documentation accordingly.

Where corrosion has become evident and is emanating from beneath a removable component (e.g. trim panel, window glass, seat etc.), remove the component as required to permit effective rectification.
