1.0 General Information on Preservation Measures

The classic quality of BMW automobiles is based on

the long-term comprehensive research and testing,

the design, the applied materials and the manufacturing

procedures in modern production plants.

BMW recommends cleaning the engine, engine compartment,

vehicle underside, axles and engine/transmission at least

twice annually, and then waxing the car or repairing the

wax coating. This should be performed before or after

the period of salt usage on streets.

New cars parked outdoors should be waxed at BMW centers

before delivery to customers. This is to avoid deposits

damaging to the paint finish, such as air-born rust particles,

chemical dust, oil saturated soot, sulfur dioxide (acid) rain,

etc. settling on the horizontal surfaces. Bird and insect

droppings as well as tree resin could mar the paint finish,

formingspots, swelling and pitting in the paint coat.

Wax films on the engine, engine compartment and

A pillars (hinge areas) are intentional and prevent

corrosion. Such wax film should not be removed.

Unwaxed cars should be washed at least once each week.

Parked cars must never be protected with plastic or

other nonporous material covers. This will damage the paint

finish due to condensed water in conjunction with plastic

softener diffusion and scratching.

2.0 Body Cavity Sealing

It is only necessary to rewax or seal the affected area

after repairing the body.

Only BMW approved products may be used to comply

with the six year warranty against rust perforation.

These products protect cavities effectively and permanently

against corrosion. Their excellent coating and waterproofing

properties let them flow into all inaccessible corners and folds for unsurpassed overall protection.

Underbody and Body Cavity Sealing Compound

For sealing of body cavities, such as doors, A-pillars, front, side and cross members, etc.

3M Part No. 8891

Würth Part No. 892080

Also: Würth “Brushable Seam Sealer”, Part No. 8901021.

3.0 Body Corrosion Protection

To comply with the six year warranty against rust, specially

selected waxes and additives produce an elastic,

temperatureproof, corrosion inhibiting protectant. The

corrosion protection thickness should measure a

maximum of 30 microns, but can be varied as desired

by repeating the spraying procedures accordingly.

Procedure:

Clean underside of car to remove grease, oil and dirt.

Cover rotating parts and parts not undercoated, such

as driveshaft, brake discs, brake hoses, springs, exhaust

pipes, etc.

After completion of body repairs, the affected areas must

have corrosion protection reapplied. This applies, also,

if the BMW Annual Check shows that the corrosion protection

has to be repaired.

Underbody Sealing

Quick-drying, rubber-based, paintable. Compatible with

PVC-based undercoat, front apron and door sill coatings.

WHEELS :

1.0 Tire Mounting Paste

Use only a lubricant specifically designed for this

purpose (former BMW Part No. 81 22 9 407 288).

Würth Tire Mounting Paste Part No. 892800

Silicone sprays are not acceptable, as they are

extremely slippery and don’t dry. If applied to the tire

bead, it is likely that the tire moves on the rim, causing

an imbalance.

See S.I. Bulletins B 36 02 88 (1627) or B 36 01 88 (1569).

2.0 Wheel Cleaners

Liquids for cleaning the alloy wheels must be strong

enough to lift brake dust, road dirt, etc. off the painted

wheel surface with minimum manual agitation, yet

not attack the wheel material. The following cleaner

has been thoroughly tested for optimum cleaning action

and long-term compatibility with the wheel’s surfaces:

Wheel Cleaner Spray BMW Part No. 82 14 1 467 045

3.0 Wheel Hub Covers

Covers may be affixed to the alloy rim by using

Loctite 638 (former BMW Part No. 07 58 9 056 030).

Covers may only be used once.

Loctite 638 - Würth Part No. 8936010

- Loctite Part No. 21447

The cooling-turbine wheel covers of the M5 (E34)

produced from March 1990 to October 1990 may be

secured to the wheel by applying Loctite 242 to the

attaching screw threads. First clean screw threads

with Loctite Cleaning Solvent 755.

See S.I. Bulletin B 36 03 90 (3182).

4.0 Anti-Corrosion Paste

Apply small amounts of Plastilube paste evenly around

the centering cone of the alloy wheel rim and onto

the contact areas of the brake hub.

Plastilube BMW Part No. 81 22 9 407 103.
