Aisin Fct-004 Engine Cooling Fan Clutch

Its Aisin, great quality and perfect fit.

Seems wrong to immediately take apart a new fan clutch to tweak it. But I adjusted the clutch to kick in earlier and changed the fluid to 15k weight (ASSOCIATED 5447 FT Silicone Diff Fluid 15,000cST,White ). Works great and because this is the famous blue shaft clutch, I'll never need another one. Just replace the fluid if it becomes weak.

This is the 'Blue Hub' fan clutch. Perfect for my 1997 Land Cruiser. I used it (unmodified) for a couple of years before I noticed a decrease in performance. I live in a very hot climate (Texas) so I drained the OEM Silicone Fluid and replaced with 20K Silicone Fluid. NOW WE'RE TALKING!Much improved cooling at low speeds. Really helps not only with engine cooling, but also pulling air across the A/C condenser which results in cooler vent temps when in traffic (low speed).Great value, rebuild-able (provided your bearing is still good and you don't mess up the sealing ring taking it apart).

Flange mount is slightly longer than the 3FE clutch (3/4”) but the 3FE clutch costs twice as much. I rolled the dice and bought this and ended up working with w CFS2709 radiator. To be clear I have a FJ80 and this is made for the FZJ80. Everything works well so far.

It’s Asin product work great but not sure which country make it look like China for me
