Volkswagen's air-cooled engine is a simple and reliable unit that can be
maintained by anyone with a basic tool kit and a willingness to learn.
The VW Air-Cooled Engine is your guide, giving highly illustrated
step-by-step descriptions covering all the tasks you are likely to
encounter, from routine servicing to dismantling and rebuilding a type 1
engine. Most of the operations described in the book can be applied to
the type 4 unit used in 1700, 1800 and 2-litre Transporter models as
well.
