Chrysler Imperial 72 radiator fan clutch

[Dragon88]

Hello,

I have to replace my radiator fan clutch but now i can choose between standard and heavy duty,
My imperial is standard do i just need the Standard fan clutch?
when do i have to use the heavy duty?

My weapon of choice is a Hayden 2747 which is a heavy duty thermal clutch.

Since you didn't put the year of your Imperial, I can't check if it fits your car. You'll have to check dimensions to make sure, matching your existing clutch with the most important being the length as you don't want it too close or too far away.
