I found a 70 gs 455 build sheet I had laying around. This is a GS 455 with Ac and the build sheet clearly shows BC code fan clutch. A bit late but still good info
On my build sheet, there is a box that is marked Fan - Under it is shroud and the code is C. Very next box is marked 3 and the code shown is G. Should my fan clutch be coded BC then ? And what is the box marked 3 for ? Thanks
