I must be missing something. The T4 was an improvement over the T1 engine by having the fan driven directly off the crank and eliminating the possibility of fan loss due to a broken belt.
Lose the electrical fans due to some sort of electrical issue or temp sensor issue and you just bought a new motor (IMG:style_emoticons/default/confused24.gif) Sure it frees up maybe 5hp by removing fan parasitic loss but at the expense of losing an engine, no thanks. Surely it has a place within a T4 conversion on a Bug, Ghia, etc but I’m not seeing an advantage within a 914 other than just being different for the sake of being different. |

(IMG:style_emoticons/default/agree.gif) (IMG:style_emoticons/default/smile.gif) the crank driven fan on the type 3 and type 4 was the best move VW ever made. in terms of engine preservation and limp home mode. re limp home mode. etched in to my memory from nearly 40 years ago in the old type 3 variant i had.
