By the time these new clutches finally clutch up and come close to water pump speed it is too late to stop the temp from continuing to creep. Look at it this way, you can try it and it cost nothing. Here is the title of the thread in heating cooling forum Hayden 2747 & 2797 fan clutches

I have not yet because I knew I was going to remove the pump. But yeah I plan on trying that.
