sorry jemal,, will tame now promise.. 

I'm trying to give you fair warning Lobster..... I'm close to permanently banning you!  Are you really trying to come off as a fool just to annoy people?  YOUR FAN IS ON BACKWARDS!  IF you are just going to belittle people who try to help. DON"T ASK!!!!

If I get any more irritation from you this week, you're gone!

i wish we met before...i wouldve treated you out to lunch

McDonalds - If you buy 7 or 8 cheeseburgers, they go down the hatch like popcorn and there's no mess to clean up.  Did this every week for 5 years, Tucson - Yuma, worked 8 hours - Tucson every Monday. 

I take it you've not had the cheeseburgers in Gila Bend!

clearly, TD has a one track mind, radiator flush for ten minutes??? what can a cleaner do in ten minutes?? he doesnt know about the word marketing strategy, the manufacturer only put ten minutes so if you use it and dont have an effect you gonna buy another bottle and on and on! like i said TD get out of that box,,, all i can say is that i have a very smooth runnin mini, aside from having to replace the main oil seal the rest are in A condition... oh TD!! stick to me and you'll learn a lot i promise u that

C'mon, 200 miles is nothing at 90mph...  If you stop in Gila Bend for cheeseburgers, the ride is finished before you know it.  Just remember to roll up the windows as you pass the cattle station outside of Dateland, phew! 

My 1/4" fan spacers are steel, the ½" is aluminum.

What really surprises me is that he hasn't replaced the belt&pulley system with an old bicycle chain and gears from a Huffy.  Logic dictates that it must be better, no slippage which equals more turning.  Good, especially if you scrape the paint off of it, it's lighter that way.  Lighter means less work, and more efficient.  No matter if the fan is inside out, as long as it's clean.  A good spray of WD40 is good for that, heck it's good for everything from shining fans to spraying boots and cleaning rusty crust from bearings that you can't see. 

OMG - scary - I stepped into Tony's world for a minute! 

Robster arguing with us is kinda like wrestling a pig in the mud...
It might take him a while.
But, sooner or later, he'll figure out that the pig actually enjoys it.

You really need to see a Psychiatrist... Wether or not folks are mistaken about the fan based on the images you took with a potato, they quite clearly explain why a fan will work, but why there is an optimal orientation. But no, Robster knows more. He makes a "funny" (tip - if you are the only one laughing at your own joke, it's not funny) joke about poor little rivets in a highly impressive claim to discredit... We don't give a frig what you do. But we collectivly try to offer advice and facts, and you decide thqt it doesn't meet with your understanding, so you seek to discredit instead of listen. Reminds me of a politican.

Next, you purchase a bottle of flush, but instead of following the instructions on the bottle, you decide you know more than the chemists that concoctd it and wrote the instructions. Now, I don't know too much about these as I'm not a chemical engineer, but every rad flush seems to say the same thing. Insert the chemical cold, run engine, drain when warm/hot. You instead let the engine pass through several heat cycles. I don't know what happens to that chemical when it cools, but I imagine there is a reason they don't want you to do this. But what do they know, they are only trained in their field, and have done testing to determine the chemical makeup and the best way to use. You have a crappy attitude and the most "rigged" mini I've seen in over a decade... Yep, robster knows best.

Like I said - the other 12 folks in the room aren't the ones who need to seek out a psychiatrist; it is YOU...

Probably installed that way so it ran closer to the radiator instead of buying the correct spacer to correct it.

Robster let me know how that 50/50 A/F mix works out for you in the 100 degree plus Arizona Summer.

Yuma to Scottsdale? That's almost two hundred miles!
What? Are you trying to get the poor guy killed?

Not trying to hijack the thread but Velocity you should fire up that Mini and drive it to Scottsdale this Saturday for the Pavilions car show.  With Barrett / Jackson in town this is usually the biggest show of the year.  On FB I'm trying to get a bunch with their Classic Minis to show up.  //www.experiencescottsdale.com/event/mcdonalds-rock-n-roll-car-show-at-the-pavilions/

correct, i dunno why these guys are making so much fuz about the engine fan blade , they even blame the poor little rivets, facing this way or that way,   at the end of the day its not how strong the fan is, its is how clean your cooling system inside the engine. if the radiator is full of dirt inside and clogging all the pins no matter how much air passes thru the radiator, it still overheat.  do what i did, i used radiator flush, but not the classic way of using it, the label says pour the radiator flush inside radiator and run the engine for about ten minutes then drain,,, What i did was to pour the entire amount of engine flush and let it stay there for 3 days, i drive my mini as usual for 3 days with the engine flush,  i drained it after 3days then poured some fresh petron 50/50 anti freeze( red) from then on the gauge always stays in the middle(max)

Air 2 Air, It's hard to tell because the photos are so terrible, but it is in fact on backwards. The fan's center should "cup" over the pulley. This particular fan doesn't have much of a cup, but it's there.

The first photo Tony posted mkes it difficult to see the curvature of the blade. But if you look closely, you can see that the concave portion of the blade is pointed towards the engine and the convex side of the blade faces the radiator. This is backwards. The concave portion should be facing the radiator. You can see the curvature I'm talking about in his second picture on th eblade at the bottom of the photo.

You guys are gonna kill me but Tony's fan looks oriented correctly, exactly the same as in jeg's photos and in every other mini photo I've seen.  I just googled for other engine bay pics to make sure I'm not going crazy.  My engine's in pieces on the workbench or else I'd check.

- Speaking as a pilot, the propeller will always push air towards the side of the trailing edge.  This has been the source of colorful stories involving drunk aircraft mechanics through history.

- Some turboprop aircraft have a "beta" braking mode that reverses the prop pitch and pushes you backward.  pull the throttle all the back past the idle setting and the throttle comes back up again, the prop sounds weird and you slowly back up.  problem is the nosewheel does not caster 180 degrees back, so it goes over to one side and you're stuck in a turn as it hits the stop.

I can't believe you are even asking this question. You must get your jolly's reading reading replies to your endless questions that have already been answered several times.

No the spacer should be aluminum but if the previous owner was anything like you it could be rubber from a scooter inner tube or handlebar grip.

here's the pic of the spacer... is it made of rubber??? i was pinching it but it feels hard, must be metal.

so having said all that, is my fan blade wring? and what do i need to do to correct it?? thanks

This will be my last post on this.  Tony, we're giving, you need to give also.  Work with those trying to help you; really, you can.

Does the curve of the blade match these pictures with respect to the orientation to the radiator?  The quick answer is 'NO', your fan is on backwards.  But why?  It still rotates clockwise - so would a pair of popsicle sticks bolted to the pulley, but they won't push a whole lot of air through the radiator.  If the airfoil concept is too abstract, try to think of the fan blades catching and pushing scoops of air through the radiator. 

To my eye, the head of the rivet is on the arms that the blade is attached to.  Where is the 'heavy' arm that is riveted to the blades in your latest picture?  Towards the radiator, which means you've got the center of the fan 'cupping' away from the pulley and the backside of the fan blade is squeezing some air through the radiator.  It's a lot like eating soup from the backside of a spoon; you won't get much for the effort involved. 

Look at the spacers used in the assembly also.  Do you have one that positions the fan close to the radiator once oriented correctly?  You can find them on the articles pages download section or perhaps linked to the fan product pages if you need to get the fan closer to the radiator. 

Really, it can't be that confusing, it's not the first time these pictures appear in this thread.  Funny thing too - the articles pages could have saved you a whole lot of trouble. 

I've seen others get confused by this, including myself, so I'll give it a try the way it was explained to me. I'm not an engineer, and I might mix up some terms, but this is how I remember it.

The fan is attached to a shaft which only spins in one direction, right? Okay, so no matter which way the fan is facing, it will always spin in the same direction. So the fan can't blow backwards, unless the motor is running backwards. Got it? 

However, the pitch of the fan is not 90 degrees to the center of the fan's rotational axis, but rather some degree less (or more) than 90 degrees. If the blades were exactly 90 degrees to the center shaft, when spinning there would be no thrust (or lift if you're talking about a propeller) generated, as all of the wind created would be coming straight off the end of the blades.

To develop thrust, which causes the blade to pull itself through the air, or in the case of a fixed fan, to move air in a linear direction, the blades must be pitched, or twisted away from 90 degrees.

So, say the pitch of the blades is fixed at 30 degrees, that would mean that if you turn the blade over, the effective pitch would be 60 degrees, which is closer to 90 degrees, and therefore would generate less thrust, since more air would be thrown outward than backward. 

End result, if the blade is turned the wrong way around from how it was designed to be, it will blow less air, be less efficient, and provide less cooling. 

I think I got that mostly right.
