Im changing from a 4 blade fan to a 6 blade. I noticed that the new fan has bent tips on the ends of the blades. Are these tips supposted to be bent towards the engine side or towards the radiator side? Presently I have them pointed to the engine side but it feels like the air is blowing out the sides of the fan instead of to the engine, yet if I put paper in front of the radiator, it will draw the paper in. I am currently having a over heating problem. The 6 blade fan is from a a/c mopar. Thanks

It sounds like it's installed correctly. Do you have a shroud on the radiator? What tells you it's over heating? Is it the gauge or is it boiling water out of the overflow?

I do not have a shroud as of yet. the gauge is showing its getting got and I can hear it boiling at the radiator cap. I already went to a 26 inch from a 22 inch radiator, now i need a shroud for the 26 inch radiator. I just don't understand why the air blows out to the inner fenders instead of at the motor

hot around town/stoplight to stoplight or out on the highway? any recent parts/systems/adjustments changes? recent issue? checked the stat? how hot?

It blows to the sides because you don't have a shroud to direct it. How about a picture of the fan installed. It wouldn't take 10 minutes to turn the fan around and see what happens.

I recently had the block cleaned up due to piston slap. Put in new pistons. Had the same problem before this happened. It would take time do to flip fan blade due to having to pull radiator to do it. When I added a/c to the car I had to move the fan closer to the radiator to clear the a/c compressor. Now only have about 1 inch gap between fan and radiator.
I have other cars that don't have shrouds and air blows back to firewall??
I seems to be mostly around town. If I let it running and parked it will eventually heat up after about 20 minutes

You need a shroud. Plus, if you check the Mopar manual, the recommended fan to radiator distance is less than what you have. Check your condensor for collapsed fins or something to restrict airflow, maybe between the condensor and radiator.

that'd be a good first step is add a schroud & locate a correct pulley cuz (with it) you want the fan 1/2-3/4 into the schroud (others will clarify on the exact "perfect" distance) but it totally changees things from the no schroud fan needing to be (correct for that system) very close to the rad

Could you take a picture of your bent tip fan and post it?

Are the tips at the outer edges, or running radially from inner to outer?

The steel flex fans have the radial running edges to "feather" the blades at higher rpm.

Back in the 1980s i had propellers for a Navaho airplane with the custom bent tips at the ends.
It sure drew strange looks at airport fueling stations.

I believe your bent tips need to point toward the radiator.

The bent tips are there to block high pressure air underneath the fan blades rushing up to the lower pressure air region above the fan blades.
This bladetip air movement creates little tornadoes at the tips that are parasitic power wasters and noise producers.

The vertical "winglets" at the end of commercial airliners are the same idea.

Yesterday I went to a car cruise and checked out two other mopars that had the same fan as the one I put on the dodge. The fan I put on is on the same way as the others. They do not have shrouds on their cars either but the air is blowing on the engine unlike mine which is blowing out the ends of the fan blades.
What the hell?????????

Put a shroud on it and call it a day.

If it a factory ,not after market,and you have the bent tip toward the engine it's on backwards.This is a factory 7 blade,what you see is the side that faces the radiator.

Concave side of blades face the engine. Always, no matter how the tips are shaped.

There is a potential confusion in that
there is a six bladed " feathering" fan design that Mopar made
which has what i would call
"bent blade edges"
running from hub center to outer edge
that face the engine side.
As the rpm increases these aero-speak
"wing edge fences"
cause the blades to reduce their angle of attack,
move less cfm of air
and draw less horsepower.

I don''t think it was one of Chrysler Engineerings better ideas
but avoids the expense of a lock-up viscous clutch.

There is no doubt that adding the proper shroud helps with any fan design.

Well it looks like I have the fan mounted on correctly. Its like 62maxwgn says with the photo he posted. So now I still need to find a shroud for the 26 inch radiator that has holes for the three studs on each side. Everything on ebay show only four holes for studs to mount. I was told this radiator came from a later model 60s c-body.
I found out that the shroud that I need is mopar#2785435.

Thanks for all the help so far, Alex
