9 CONFIRMING ELECTROLYTE LEVEL

WARNINGS:


BEFORE CHECKING AND TOPPING-UP THE BATTERY ELECTROLYTE, REFER TO THE HEALTH AND SAFETY PRECAUTIONS
SECTION.


AGM TECHNOLOGY BATTERIES ARE FULLY SEALED FOR LIFE AND NO ATTEMPT SHOULD BE MADE TO CHECK OR TOP UP
THE ELECTROLYTE LEVEL.
On certain types of battery the electrolyte level may need to be checked.

Make sure the battery is of a type suitable for topping up. These types of batteries will have cell plugs visible on the
top face of the battery or a removable access panel to allow access to the cells.
On batteries with a clear or opaque case and level marks, check the electrolyte level by visual inspection of the
maximum level indicator mark on the battery casing indicating adequate level above the battery separators.
On batteries with black cases, remove the cell plugs or access panel and ensure the electrolyte level is level with the
indicator in the cell hole. A flashlight may be required to see the electrolyte level on this type of battery.
If the electrolyte level is low, top-up using distilled water.


NOTE: Maintenance free and Valve Regulated (AGM) batteries are sealed and therefore cannot be topped up.
CAUTION: DO NOT overfill.

metal surfaces are bolted together always interpose a suitable interface material such as weldable zinc rich primer, extruded
strip, or zinc tape.

Steam Cleaning

Due to the high pressure/temperature generated by steam cleaning equipment, there is a risk that certain adhesives and
corrosion prevention material may become softened or liquified.
Take care not to allow the steam jet to dwell on one area, and keep the nozzle at least 300mm from the panel surface.


CAUTION: Do not remove wax or lacquer from underbody areas during repairs.

Inspection During Maintenance Servicing

It is a requirement of the corrosion warranty that the vehicle is inspected for corrosion by a Jaguar Authorised Repairer during a
routine service, to ensure that the factory-applied protection remains effective.

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.

Underbody Protection Repairs

Whenever body repairs have been carried out, ensure that full sealing and corrosion protection treatments are reinstated. This
applies both to the damaged areas and also to areas where protection has been indirectly impaired, as a result either of
accident damage or repair operations.

Remove corrosion protection from the damaged areas before straightening or panel beating. This applies in particular to panels
coated with wax, PVC underbody sealer, sound deadening pads etc.


CAUTION: Do not use oxy-acetylene to remove corrosion prevention material. Large volumes of fumes and gases are
liberated by these materials when they burn.

The most common method of removal is by means of a hot air blower with an integral scraper. High temperatures can be
generated with this equipment which may cause fumes. Take care during its use.

Structural Adhesive


CAUTION: When separating a joint with metal to metal adhesive, it is important to avoid distortion. Heat gradually until
the bond weakens sufficiently to permit panel separation - do not apply excessive heat.


NOTE: When spot welding through metal to metal adhesive, take particular care to adjust the equipment setting to
ensure a suitable weld.

Metal to metal adhesive is applied to critical joint areas during factory assembly. The material used is a high temperature,
heat cured, nitrile phenolic which serves to bond two metal surfaces and also to seal the joint against ingress of dust,
moisture and fumes. This material is not suitable for service use and, during repair, should be substituted by an approved
structural adhesive. For panel specific information and to identify the areas of structural adhesive application in repair, refer to
the relevant sheet metal removal and installation procedure.

Expanding Foam Acoustic Seals

Expanding foam acoustic seals are used in various closed-sections of the body to improve vehicle refinement. The seals are
installed during the vehicle body manufacture and expand during the paint process up to ten times original size, thus locking
them into position. They are located such that they prevent noise accentuation along a section and reflect air borne noise
away from the cabin.

The seals have spilt functionality depending on location. The seals located at the base of the body pillars have a primary
function of preventing water ingress when wading. Their secondary function is to prevent noise and dust ingress.

The seal around the fuel filler has a primary function of preventing both fuel and water ingress. With a secondary function of
preventing noise and dust ingress.

The remaining seals primary function is to prevent noise accentuation along a section and reflect air borne noise away from the
cabin.

Another advantage of the seals is that they marginally increase the overall stiffness of the body and its structural performance
in case of a crash.
The seals are manufactured from an expandible polymer.

Replacing Expanding Foam Acoustic Seals

As paint oven temperatures used in a repair workshop are significantly lower than those that are used during manufacture of
the vehicle, (the temperatures are not sufficient to expand the foam), a different process is required to replicate the foam in
repair.

- Air flow checker
- Sealing compound (tape and plastic compound)
- Multi-purpose sticker
- Clinched flange sealer
- Window sealing compound
- Water shield (PVC)
- Double-sided adhesive tape for water shield
- Methylated spirit (available from trade outlets)
- PU adhesive
- Silicone remover
- Tar remover

Water leaks according to mileage or running time
Increasing mileage has an effect on the problem of leaks in a vehicle. Possible influencing factors are:
Servicing and maintenance of seals:
- No maintenance, lack of maintenance or incorrect maintenance
- Using an incorrect agent
Damaged seals:
- As a result of aging, wear or incorrect handling/assembly.
Heavy soiling of the vehicle:
- Heavy soiling of a vehicle can seriously impair the function of water drainage channels in particular, and also of
rubber seals.
Age-related factors:
- Environmental factors
- UV radiation
- Extreme climatic conditions
Corrosion can have a serious impact on bodywork, in particular as a result of:
- Lightly or heavily rusted seal carriers
- Rusted body seal welds
- Perforation corrosion

Water leaks after body repairs
If a vehicle develops a leak after body repairs, the following points must be taken into consideration in particular:
The correct seating of ancillary components and their seals must be checked.
The correct alignment of doors/tailgate and liftgate must be checked. The associated seals must not be damaged and
must be installed correctly.
Check that panel seams are correctly sealed.
The correct seating of rubber grommets must be checked.
Directly-glazed windows must have correct and complete bonding.

Water drainage system

If a vehicle develops water leaks, then areas into which water is routed or drained should be checked first.
