My 7.3 diesel wasn't coming up to temp. After some poking around, I found that the fan clutch had seized. It's supposed to cycle somewhere between around 25% and 80% of the water pump speed. With it seized, it was spinning at 100% of the water pump speed 100% of the time. Time for a new one.
I tried every trick in the book to get that fan clutch broke loose. I used ratchet straps, duct tape, pipe wrenches, you name it. I even rented a tool from the parts house. I wound up buying it, not because it worked but because I broke it. That fan clutch was stuck on but good.
I found a video of a fella using this tool set and I figured why not? I'm a suborn old coot and I flat out refuse to take my truck into the shop just for a stupid fan clutch. So I ordered this and bought a decent air hammer from a store in town.
In the video, the fella just gives it a little BURP and the fan clutch is loose and spins right off. I had to jam a screw driver into the bolts, stand on it with one foot and BUUURRRP. It turned but was still tight. Got a fresh bite and BUUURRRP. And one more time. BUUURRRP. I had to turn it a full 180 before it came loose.
This is the only tool that could get the job done. If yours is on just regularly tight. then this thing will get the job done in three minutes instead of an hour. But if yours is super stuck on like mine was, this is the only way of getting it off without damaging the water pump. Best hundred plus bucks I've spent in more than a year. And it saved me the embarrassment of having to take the truck to the shop. Small town. I'd never live it down.
