What temp thermostat do you use Gordon.

I recently replace my failed fan clutch with a 4644......for 3 years I never heard the fan run and my engine always ran cool......now it seems like the fan is kicking in all the time.

Rick;
I find the description slightly misleading. The rating of heavy, normal
or light does not describe the strength or projected life of the clutch.
It describes the % of coupling. As in 65% of engine speed for light
duty. As I have said many times, I prefer light duty clutches because
they do a more than adequate job of cooling for me with a stock
radiator. One gets better gas mileage with a light duty clutch and the
noise level is way down when compared to a Heavy duty clutch. I know
the consensus is a heavy duty clutch with a 195* thermostat to keep it
roaring as much as possible, I just don't get it?
I am now doing the most daft and unthinkable conversion to twin 17"
electric fans. The fans were free, so I have nothing but a few hours
labour to loose. I am looking forward to being able to get in and
change rad hoses without finding a midget with 4' long arms to assist me.
