Just found a new DIY site from Thailand, in Thai and English.

so he really goes into detail and explains first for what the fan clutch is etc., how to make your own fan clutch tool

When the fan clutch is not good, we offer two ways for your consideration as following.


Replace bad fan clutch with the new one, very surely and not difficult to do but more little expensive.
Rebuild the old fan clutch by drill a hole on the fan clutch body and refill hydraulic oil inside and firmly close that hole when finish. This method I never did before, but heard from some one that it has good result and low cost, if you have interest you can search in anoter website.
