9 Blade Fan Retrofit - Added by: Tom
On my '95 Suburban, as part of a full cooling system maintenance (first time in 10 years, 177 K miles - radiator rodded out and fins cleaned), I removed the stock 6 blade fan, and easily bolted in the 9 blade and driver. It pulls air through the radiator like a hurricane. No trimming was required to the shrouding, although I would note the clearance is pretty tight - about 1/4" to spare. Fan is quiet - performance is outstanding.
