I own a saff 4x4,the last 2 days i noticed that the fans ,stop running when i swich off the engine...
Normaly...used to run only one fan with the engine stop..running for a few minutes and then stop..
But now when i turned off the engine one fan is not remaining for a few minutes...What happend???sensor???fuse????wiring???

 

the fan wiring on saphs is a common fault, they corrode and fall apart from the inside out
best thing to do is rip all out and replace it all
theres kits on ebay now with motorsport spec wiring thats a direct replacement
i'd get 1 of those if i was you
