Volkswagen Golf Service & Repair Manual: Corrosion protection measures for wing surface in contact with wheel housing
liner
Note
| |
The corrosion protection measure is to be carried out in the groove
of the wing of all new replacement parts which have not had the
additional sealant applied at the factory. |
| |
The additional sealant is intended to prevent the wheel housing
liner from possibly “scouring” the groove of the wing, which could cause
corrosion. |
| – |
Apply surfacer on inside and outside of wing. |
| – |
After surfacer has been applied and has dried, apply and spread
sealant -D 511 500 A2- in the contact area of wheel housing liner
(groove of wing). |
Note
| -Dimension b- can vary because the
width of the edge of the groove differs among wings. Always ensure that
the entire edge of the groove is sealed. |
| Before installing, seal inside of wheel arch and web plate
with cavity sealant. |
