    I had just left my fan black, too (lazy and eager to get it running). From your experience, I think I'll paint the tips too. With my engine being blue, I've been thinking of maybe an electric blue of some hue. Whadya think?

    You'd be amazed how just a 1/4" line near the tip gives the same effect, without the full 4" of tip being painted.

    I also just try to keep my fingers away while it's running - just as a general practice.

    Blue Tips

    Hello, Gene.

    I would use a light-colored blue so that it shows up well. If you are just painting the tips, you might be able to paint them without removing the fan.

    When I thought about a blue propeller, the the first thing that came to mind was the BMW logo:

    But, it turns out that the BMW logo actually does not represent a spinning propeller.

    "You'd be amazed how just a 1/4" line near the tip gives the same effect, without the full 4" of tip being painted."

    I wish now that I had included a yellow stripe behind my red one:

    Coolant Expansion Tank

    Uhhh, ... I am going to make another improvement.

    The coolant expansion tank that I have been using for the past couple of years came from Mac's auto parts and was listed as being for a 1963 Falcon. It measured 2" x 12" and holds 20 oz of coolant.

    The trouble with the 20 oz tank was that it was not big enough. When the full radiator got hot, the coolant would expand and overflow from the tank. When the radiator cooled back down it was no longer full.

    Yesterday morning I saw a 3" x 12" coolant expansion tank that holds 45 oz of coolant. Oooooh ....
    See: http://www.amazon.com/Speedmaster-PC.../dp/B00SYFU2B0

    This should work nicely. It will allow the radiator coolant to expand without overflowing. That way, the radiator will stay full when it cools. That will allow the radiator to function at maximum coolant capacity and cooling efficiency.

    On an unrelated note: My steering wheel had begun squeaking when the wheel was moved back and forth. This afternoon I sprayed some WD-40 into the narrow separation between the steering wheel base and the turn-signal hub using the soda straw applicator. The squeaking disappeared. Yaaay!

    So, Dennis - are you actually expelling more than 20 OZ of coolant when your motor gets hot and it is spewing onto the ground as a result? Or were you saying it wasn't sucking it back when it cooled? What radiator cap pressure are you using? Looks like one of those thermometer caps from the picture. Just curious more than anything what the condition actually is.

    Spewing and sucking? That's sounds rough.

    Hello, Roger.

    No, the fluid expands and then it goes back down when it cools.
    The problem is that when it expands it expands more than the 20 oz volume of the expansion tank. Anything in excess of 20 oz overlows the expansion tank

    When the radiator cools off it sucks the remaining 20 oz back into the radiator, minus whatever overflowed from the expansion tank.

    I am not talking about a huge amount of overflow. Maybe no more than a cup full (8 oz). If I had a bigger expansion tank there would be no overflow. The fluid would heat and expand and flow into the expansion tank, and then cool and contract and flow back into the radiator.

    Hello, Roger.

    I am using a 13 psi ThermoCap.

    ThermoCap1.jpg

    I bought it about a year ago. New Made in China Mr. Gasket 2470S Domestic ThermoCap 13 PSI-SLVR from Amazon for $17.27 with free postage. "Combines a pressurized radiator cap with a thermometer element that eliminates potentially dangerous guesswork."

    Looks similar to what I installed - probably is. I can't remember what pressure I went with.

    It's been a while since I looked into all of this, but it prompts me to look into the whole pressure rating versus coolant temperature - and how we survived before expansion/coolant recovery tanks - topic. Seems to me you use a lower pressure cap for a expansion system and higher when they were not used. But it's fuzzy - up there.

    Hello, Roger.

    Since you asked:

    My 1963 V-8 Falcon uses a 13 psi cap as its stock, original equipment cap.
    The boiling point of a 50/50 mixture of antifreeze and water is calculated by assuming that the non-pressurized boiling point is 223°, and that each pound of pressure raises the boiling point by 3.25°. 223°+13*3.25° = 265°.
    The radiator boiling point with a 13 psi cap = 265°.

    For a radiator without an auxiliary coolant expansion tank, you do not fill the radiator completely full. You just add enough coolant to cover the tubes and leave head space in the top tank of the radiator. When the fluid gets hot it expands into that head space.

    The advantage of an auxiliary expansion tank is that it allows the radiator to be filled completely full. When the coolant gets hot it expands into the auxiliary tank and then it goes back to the radiator when it cools. Having the radiator completely full all the time makes the radiator more effective because it contains more coolant and does not allow air bubbles to circulate through the cooling circuit.

    Thanks Dennis - Feel gooder knowing that I knew all of that. I guess the fuzzy part was what they used to determine the pressure of a particular system. Why isn't there 15 lbs caps, or 18 lb caps on every car? Balance between the pressure the system can take and the temperatures they want to hold to.

    That's what I'm looking at. Probably not an easy research thing, but I see some pages where they are suggesting an 18 lb cap, which might exceed the working pressure of a particular system. If something were to blow (other than the cap), what would that be?

    I also found this quite interesting!
    How do I know I have the right psi cap for my falcon?
    (Darn...I'm not near my books any more.)
    I should probably let a little fluid out of my tank....I think I filled it to the top.

    I have the smaller recovery tank on mine with no overflow problems. I do have a 3-core radiator though, and that may be the reason.

    Also, I tried brightening up my fan with blue (experimented with blue tape), and found it wasn't as bright as I liked. Today I purchased some fluorescent yellow at our local Home Depot. I'll do the tips with that and post the results reeaall soon now (maybe real soon this fall).

    I got my fan tips painted today. They are definitely more visible now. Thanks for the idea, Dennis. I suspect that I'll install a shroud sometime in the future.

    Hello, Gene.

    You might be thanking me too soon. I painted my blade tips with latex paint so that the red paint would not dissolve the black engine paint that was used to paint the fan. Well ......

    The paint on the front of the blades has held up great:

    IMG_0483.jpg

    But the vacuum at the back of the blade tips was powerful enough to suck the paint right off. Wow!

    IMG_0484.jpg

    We will have to see how yours holds up. What kind of paint did you use?
