Does this fall into the storing of a modern style battery case on bare concrete to use or not to use wood category?
I have my opinions but would like to hear others

Well, I am not a radiator specialist, but after discussing this with folk who are, my determination is you can get the same flow rate with 1/3 the radiator clear as you can with the whole thing clear.
So I think that testing a radiator by flow method will show you that you have at least a 1/3 clear-ish radiator, it is no indication of the amount of cooling capacity the radiator has.
Take mine for instance. I have been working on getting the engine running temp at or about 160° since I got this car in Oct '16, but it wasn't until yesterday that I was able to get that for any length of time. Now I am using the stock pump, but an electric fan mounted to the radiator. Now having said that, even with the fan running, at 40mph-ish, I was not able to maintain that temp, but did see a raise in temp above 40mph. To me that says the system still has a problem, even though I am chasing it down, I don't think I am there just yet. Now, before anyone asks, I have the Nu-Rex centrifugal advance so it shouldn't be a timing issue since it should keep the timing near the same no matter the cooling system since it is RPM dependent.You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command! -
I say yes it is like storing a battery on concrete. It is BS, but we better ask Bills dog to know for sure.Comment

A quote from Marco's Barnyard site::
"""Don't be fooled by flow testing! Flow testing your radiator as suggested in several publications will only confirm EXTREME problems. You can block more than 1/3 of the cooling tubes on an original radiator and pass the flow test. The reason for this is the lower water outlet of the radiator is the restrictor. It is designed to limit the speed the water travels through the tubes. More time in the tubes equals cooler water."""
In addition to the above even flow testing a replacement radiator, modern car radiator or any radiator is futile.Comment

Humble and sincere opinion for: Radiator flow test fact or fiction?
A "Radiator Flow Test" is a Fictional test that is a Fact; and,
A "Radiator Flow Test" is also Factual test that is a Fiction; and,
If one's normal, rebuilt engine overheats in summertime .... it is a Fact ... rather than a Fiction ... that one either needs to clean one's radiator, or buy a new one.
And that's a Fact, Jack .................. and definitely not a Fiction ..... or even a Prediction!Comment

The flow test does not take into account any heat transfer from the water in the tubes to the fins and then to the air. If the fins are not attached to the tubes or there is to much paint on the radiator it could flow within specifications but will not cool the coolant

They stored batteries on WOOD, cuz the cement floor had disintegrated & disappeared from ACID leakage!

According to les Andrews q and a mafca 2012. The stock radiator holds 1.5 gallons. If it won't take the full amount, then your plugged. At that point the 1.5 gallons should run out in 4 seconds. Although, the only thing I can visualize slowing the flow at that point would be a wrong or deformed lower outlet. Which I understand to be sized as a restriction to control the flow rate.Comment

I once bought a 36 month battery that was too small for the stock battery box in my pickup. I built a box out of 1/2" plywood and set the battery in that within the stock metal platform. That made the battery secure, and it lasted for over six years. That might have been coincidental, or it may have just been a better battery than the usual group 1 I buy.

I am just curious if anyone here has ever installed an electric fan on the front of their Model A radiator. Before you scold me, I know it won't look right... but I have a reason. Here in Texas it gets extremely hot & I drive my car year round. I have an AC so when it's 108* outside, I am comfortable in the car. When it's this hot outside, my car does not overheat. Going 55 MPH down the highway...03-21-2019, 11:25 AM -
Along the lines of Mitch's post, I don't know the answer to this, but so many of us have had problems with cooling and the blocked radiators, I wonder if there could be some good calibrated check of the rate of flow through a radiator. For instance, keep pouring water into the radiator so that it is full (flowing out the overflow tube and top of the radiator won't matter) and then disconnect the...08-13-2017, 08:03 AM -
Yesterday I took my longest road trip to date since buying Rose. Purring down the road at 50+ mph and then the Quail in front of me started pissing in my direction. Boy of boy was it hot. So to stay positive, I'm pretty sure I boiled the radiator clean;) After reading most of the threads on radiators and cooling issues, I have a plan of attack to determine if I damaged anything. I do not have any...07-14-2019, 09:20 PM -
See the attached photo. This was taken a couple months ago when it was still colder outside and I would go out to the garage every week or so during the winter and start the car up for a while or even take it for a few mile drive. Since then I cleaned it out, but now after about 100 miles and warmer weather, it is forming again. Weather now is in the upper '70's to low '80's

Well now I have done it. Started with installing a new Auto-Meter temp gauge as per T-bird. I got the 180 deg. antique version with large numbers. Next I followed a very extensive article by Andy Wiedeman called COOLING SYSTEM SEMINARE dated Feb 25 2012. Tried to post the link but would not work. Drained and flushed radiator, pulled out thermostat, filled with distilled water and water wetter....06-17-2018, 09:17 AM -
I need to get a new radiator for my late 28 roadster. The good news is that there are options. The challenge is that there may be more than one good option. Here is what I have narrowed it down to:
1. New Berg's radiator
2. New Brassworks round tube radiator
3. Have Bert's recore my old radiator
Many people love Berg's radiators. They don't recore anymore,...12-02-2018, 08:11 PM -
so i have a clean new radiator and a clean engine with 60 miles on it. My temps are around 195 and rise when at idle. Is this do to a tight engine? I’m not running rich and timing is good. I do run the nurex Auto advance and no stat....09-26-2018, 07:44 AM -
Last time I drove my ute any real distance, it overheated and boiled. I blamed a dodgey thermostat so I removed it. The trip home (over 100 miles) was uneventful so I thought I had solved he problem but yesterday, I went for another run and one way, things were fine but on the way home (this time about 23 miles each way), I saw the temperature spike and the engine boiled again. (remember there is...01-07-2020, 06:24 PM -
I have read that the Model A has a Thermosyphon cooling system, even though it does have a water pump. I read where the clearance allows water to pass the water pump impeller if the pump were not operational. So if you had a fan belt break or some other issue that you had to run the car without the water pump operational, still mounted on the motor but not spinning, would the thermosyphon action work...06-01-2018, 02:59 PM -
I recently purchased a very nice Brassworks radiator. My old radiator had no baffle in the filler neck, so I could plainly see where I wanted to fill the level with coolant. I would fill it to just a little over the tops of the tubes because if I filled it more than that, it would all blow out anyway. That old radiator was falling apart and took many fills to keep it in water.
This is...08-06-2019, 03:02 PM
