It is definitely one of the best alternative ways of converting a Type 4 engine to a upright fan, since many of the existing parts can be reused. As a result of the standard design a good cooling air distribution is guaranteed.

Original 32kW / 44HP or 37kW / 50HP fan housings can be used.

The production standard oil cooler is removed and need to be replaced by a front oil cooler.
