Review on 🔧 Hayden Automotive Premium Fan Clutch - Model 2797 by Mark Harrison

This keeps my 81 El Camino decently cool with a 350 swap. This is a great fan clutch when you want to make sure your classic car or truck doesn't go over 220 degrees. My El Camino would have overheated to at least 225F in traffic but now it doesn't go above 210 degrees. I'll be working harder on the truck to keep it even cooler, but this clutch locks it up almost 1 to 1 when it gets hot, lowering the temp drastically. It does have some fan whine when it's on, but it's worth it when engine temps are low. If that doesn't work or doesn't work when it gets really hot this summer I'll post an edit/update. But I am very happy with my purchase. UPDATE 1: I did some more work on the small block and increased the time, the engine doesn't even see the 210F. When I hit the gas hard uphill the fan slows down which spoils the fun a bit, but that's the price I'm willing to pay for a cool truck. Nevertheless 5 stars! UPDATE 2: It is now October and my experience confirms what others have said and what I have said before: it just works. My truck no longer heats up. There was a moment when it got hot, but that was my fault. For some context I climbed a mountain pass on a hot day at about 70-75mph and at the top of the mountain (about 3 miles later) I was at 220F. At such speeds, the fan has nothing to do with cooling your car. I should have shifted out of high gear, but I didn't. So, the engine got a little warm, no big deal. I love this fan clutch. It runs anytime your fan can cool the motor. Feel free to buy it. You will not regret it.
