Toyota Fan Clutch Silicone Oil Part Numbers

"The Toyota dealer says there are three types of viscous fan clutch silicone. They are rated at 3000 CST, 6000 CST, and 10,000 CST. (the higher the Cst rating, the higher the viscosity (THICKER fluid) All priced the same. The only reference to this stuff that the Toyota parts jock could find, was a TSB from 1975 specifying the fill procedure for the clutches of that year, The 3,000 Cst. was for all Toyotas except for the Celica (the only “sporty” car they offered in 1975), which got 6,000 Cst. The 10,000 Cst. was not assigned an application by the TSB. He guessed maybe the Land Cruiser but didn't really know. Anyway, the part numbers are 08816-03001, 08816-06001, and 08816-10001, respectively.(Each bottle is 18mL; you will probably need 2-3 bottles depending on your specific fan clutch)"

Thanks Jon, Soo....what is currently in our oem fan clutches.

 

I don't understand why anyone would bother a new aisin fan clutch for the tow package from cockauto is $85 vs. spending $36 on three bottles of mystery goo to put in a used clutch that has other wear parts

 

So I followed a link below the article and one guy used a syringe to force the silicon fluid in. I don't see how he was able to remove any though.

 

You split the fan clutch in half by unbolting the two halves. You can get the same fluid from a RCHobby shop for $15 or Amazon.. Its used in the differentials.

 

I believe it's the 3000cst or wt.

 

It only requires 2 bottles from Toyota or 1 bottle from a RCHobby store.
