Ford Sierra 4x4 Supplement Manual
The Ford supplied Sierra 4x4 Supplementary Workshop Manual is
a "must have" for any owner of one of these cars. The biggest
problem can be actually finding one to purchase. I got lucky and
managed to get mine direct from a Ford dealer, brand new for Ł8,
who was having a clearout. They do appear regularly at
autojumbles and it is just a case of keep looking. The manual only
covers those items unique to the 4x4 Sierra's and are to be used in
conjunction with the Ford Sierra Workshop Manual. Ford never
produced a supplement that covered the 2.9 engine or the later
Mark Two model but all the running gear sections are relevant as
this never changed during the life of the model. I believe there is
also a supplement that covers the MT75 gearbox for the 2.9
models. I have included below some information and diagrams that
maybe helpful to owners.
