Fan Clutch and Coolant

[Laser]

Hey guys,

Went out to change my waterpump today but couldn't get the fan clutch off. I can't find a removal tool near me, tomorrow I'm going to try an air chisel. Any other tips?

Also, I bought some coolant additive today made by Fram. Not sure if this will work in my engine, anyone used it before?

Thanks

I'm having the same issue with the fan!
Hopefully I can get this sucker off!

I jsut re-did the entire cooling system in my buddies 7.3. Let me tell you what... haha

wait until you can find the wrench. My local O'Reillys had a couple, so they should be fairly easy to come by. Worst case, get some flat stock and cut yourself one. I fiddle-f**ked with his for so long, only to run back to the parts store and buy the stupid wrench.

Also, it's WAY easier to pull the radiator out first, then do everything else. One of his water pump bolts was seized, only to discover the bolt head had fuzed to the pump housing. The threaded parts came out by hand after I cut it out.

I'm sure somebody else can help you out with the additive in here. I'll be doing my coolant system after the New Year.

oh, and regardless of what you read anywhere, the threads were NOT reversed on my clutch fan!!! check the new clutch fan and you'll see what I mean.

And if ya got time, look into putting a 6.0 plastic fan in place of the 10 lb steel 7.3 fan.

I found the wrench, but not the holder. I couldn't find a way to secure the pulley well enough so I ended up pulling the waterpump out with the fan still attached to it. This required me to pull the radiator out first.

After that I just clamped the impeller on the pump and the fan came right off.

I usually use a strap wrench to hold the pulley. Some guys will say to just leave the belt on, but there isn't enough traction to keep it from slipping if the hub is on tight.

I've always used an air chisel to knock the fan loose.

leave the belt on. put wrench on the fan, then HIT it with a hammer. Knocks it loose every time

I agree, there wasn't enough traction from the belt. I tried the air chisel and hitting the wrench with a hammer, I even put the air chisel on the wrench.

Turns out someone had put red loctite on the threads... That may have had something to do with it

I've also taken a ratchet strap and wrapped around the belt to add more tension when braking it loose.
