good day guys, I have a question, I had a real bad water leak front of he engine, I removed the water pump because I think I ll try new one to see if that fixes the issue, question is how does the fan come off? Mine seems stuck I removed the 4 small bolts and I don't want to force it and break something, thanks

Inspect it carefully for any cracks at the base of the fan blades. Even if you don't find a crack, if it is the original fan you might consider buying a new one, as when an old fan blade breaks off it's not a pretty sight. That happened to me in 1990. Fortunately the fan blade stabbed into an inner fender instead of coming up through the hood.

Hi Tommy, great save there. I don't recall where I heard it but it's a lot more common than it should be.

One guy suggested not to put the 216 fan on the later smaller water pump pulleys as it will be spinning faster and therefore even more likely to fail.

Hi Robert, Bit of luck there too for you, not having it mess up the hood. Do you think a simple shroud would have caught it.
I won't use the old bimetal flexi fans for the same reason of cyclic failure chucking a blade.
The latest plastic ones are much safer but kinda don't look right.

Cheers Kiwi

I don't know Kiwi. Scared the crap out of me when it happened--I was doing about 65 on a So. Cal Freeway, and the vibration was severe.

I doubt it, when one of those blades decide to leave home it goes and would probably take a simple shroud with it. One made of tank armor might work though.

I'm going to third the opinion of replacing the original fan. I was doing about 70 on the highway with my stock '50 when the fan blade went and stabbed itself through the driver side fresh air duct and embedded itself halfway through the inner fender. It scared me pretty good as I thought I slung a rod with the butt shaking vibration going on.

I did not see any cracks in it beforehand, however someone else (myself included) used it to turn the engine over by hand for valve adjustments and bent one of the blades out of alignment. A close inspection on the broken blade reveled that it had a rusty hairline crack in it for years.

Hi Kyle, there would be very few that weren't used for that trick somewhere in their lifetime.

It just happens there is something funky about the way they were pressed or formed that has a more than normal failure rate.

It's just a shame that the modern plastic ones just look, well, so plastic and out of place.

A simple drum shroud may shield them from view. Perhaps cutting down a later model drum type to just cover the fan.

If you started with one of these 64 repo ones you could un spot weld it to make it split for removal and shorten it down and rework the side frames to fit the right spot on an original radiator.

Simple shrouds do a lot of good for what they cost and have been on everything for decades now. very effective if you have low engine revs as they help fan efficiency in that troublesome phase.

The latest hobby nylon fans look a little better. From what I understand you can get 18 3/8", 16", and 14" from various makers.

Cheers Kiwi
