Radiator Fan Bolts - need quick help

Hi All,

I'm in the middle of remounting my radiator fan with new hardware. Quick question, how tight do I torque the mounting bolts?

My question is b/c I know the rubber bushings in there are supposed to provide some vibration damping to the hub. And, if I crank it down too tight, do I defeat the purpose of the rubber bushings?

I can tighten them to just snug. Or, crank them down fairly tight. Either way, the tab washer will lock the bolts in place once I bend the tabs up against the bolt heads

Thanks for a speedy reply

Bob
 
There should be steel sleeves inside the rubber bushings; the bolts pull down against the sleeves. At least that is the arrangement on the earlier TRs, I assume it is the same for a 4A. 8-10 ftlb should do.
 
Thanks Randall,

Yep, got the steel sleeves in there. I just checked my Bentley manual which advises 16-18 ft/lbs. I have a torque wrench but, I think it is a large 1/2" drive unit. So, it may not be sensitive enough.

Anyway, 16-18 sounds moderately tight. More than "just snug" but less than "cranking them down".

Thanks for jumping right on this.

Yep, got the whole fan mounting kit from TRF. Comes with everything. Part no. RFK538.

Cheers
