I did some research online and found that pretty much every fan clutch on the market, minus two or so, are made by Hayden, regardless of their color or box they come in, or the store that sold it. Our AHB's call for an HD clutch and that's exactly what I bought when my stock clutch locked up. What I didn't realize, or want, was the fact that it was engaged 90% of the time and it drove me crazy. The only time it kicked off was after about 20 minutes of driving at highway speeds, or a WOT run from zero, and it the upper band of 2nd gear, it finally kicked off, but came right back on the second I slowed to a stop. I simply didn't see a reason this thing was engaged all the time. I'm not running a plow. I'm not towing up hills all day. I didn't get it.
Now, I'm in Florida, running a 3 core radiator upgrade and the only time I saw any fluctuation in the temp gauge was with an electric fan that I took off after a week.
I bought the ACDelco standard duty clutch and I love it so far. This is as hot as this car will get, day, night, idling or at highway speeds. Keep in mind, I'm running a brand new motor.
Also, I grew up in a suburb of Syracuse. I know exactly where you're from.
