2h fan clutch check/refill

[coldtaco]

So, after reading the different threads on checking and filling 80 series fan clutches, was wondering if anyone can shed some light on this? My clutch looks different from the 80 series type. Operation is same I would guess. My question is where to do I fill the fluid to? Fill till it is flush with the round holes?
Thanks

When I replaced fluid in my BJ70 clutch fan, it was a measured quantify that I put it. 50ml of fluid. Will try to attach document.
