Model A Engine Cooling

Think about this: ANYONE who runs a Model A WITHOUT a good temperature guage is in serious need of some common sense counseling! Bill W.

Hi Bill,
What's the diff. if a temp. guage shows that you are eng. is running hot, Or you have water coming out of your rad. cap and getting on your windshield, they both tell you the same thing, And I would go by the cap spewing hot water on my windshield then some temp. guage.
How have these little car's gotten by for 80+ years ?

A lot of good info on Evans . What is the procedure for purging the radiator in preparation for installing evans .

Thanks

Duffy1 - Basically, you drain out what is in there. Then, they have a converter that you put in the system to make what is left compatible with the new stuff. Then, put the new stuff in.

It is not a hard process and there is a page on their website that discusses it. I would recommend calling them directly for more exact instructions. Since the Model A does a pretty good job of draining, they may tell you that there isn't enough left in the system to worry about.

I admire your plans to re-restore your coupe,but if it was me ,I think I would find a similar car & use your interior & top kits in it,especially if the body is warped out of shape.Of course,nothing is impossible-All it takes is time & money!

The coupe restoration won't be too hard. I have worked on much harder projects.

Louis,
A proper cap is NOT vented & will not "spew!" I'm sorry I even said anything. Was just trying to help, but some don't want NO help & won't ever change their ways. Maybe I'll just go back to collecting BEER CANS! Bill W.

Well when mine starts to get hot she runs to good an i get concerned and check everyting 90% of the time she runs to good shes blowing steam out the over fill pipe. im just useing water cleaned raiadtor with vinager and no problems hasent overheated in a long while unless i for get to check watter lebel in the morning (have a rad leek) but the simple fact oof the matter is if everythings right u wont overheat.

[28ACoupe]

1928Pickuppain - while it is true that if your cooling system is working fine you won't have a problem, you still have to replace the coolant every so often. The Evans product is a lifetime product. I.E. you put it in and forget about it. No need to change it like water or 50/50 mix.

[MALAK]

I agree with 28ACoupe and will be converting to Evans in the near future. That said there are some disadvantages with Evans that IMO are out weighed by the advantages. These are:

1) Higher initial cost. Four gallons of Evans is about $178. This cost is offset over time as Evans is considered a lifetime coolant. No more replacing coolant. And no more conventional cooling system maintenance i.e. draining, flushing, refilling. It's hard to put a price on that as my time is valuable to me.

2) Should a leak occur you can't just add water (or standard antifreeze) to make up what was lost. You can however use a propylene based antifreeze such as Sierra as make-up, temporarily, but this would dilute the Evans. Best to take an extra gallon of Evans if going on a longer trip. This disadvantage is reduced IMO due to the fact that using Evans reduces the chance of getting a leak in the first place by eliminating the compounds that attack the hoses and cooling system metals as conventional antifreeze/rust inhibitors age. It should be noted that Propylene Glycol (the base of Evans) forms lactic acid in the presence of air and heat so to be used properly should be used with a radiator overflow catch-can and a good radiator cap.

Disadvantage #2 is why I haven't converted yet. I haven't devised an overflow catch-can that meets my desire of inconspicuousness. When I do I'll convert and post pics.

Malak - Whether or not you convert to the Evans product or not, leaving your driveway without an extra bottle of coolant in your car is just dumb.

Also, when running this product in the coupe, Neither dad nor I noticed any tendency for the product to overflow at all. Again, if your cooling system is in good shape, there should be no issues.

aw hell ,all this talk about over heating, flush out your block,get your radiator recored or replace it with a new one,install a thermostat along with a temp guage,no more guess work. Bill W. is right on !! I had the same problem,now it runs a cool 160 degrees and it was 108 here yesterday.

[JBohannon]

It worries me some that this type of coolant will not boil until 400 degrees. My wife once accidently boiled all the impurities out of a cup of water in a microwave and when she put the tea bag in it basically exploded. She has a nasty burn on her hand. I am just thinking that someone could make a mistake and get a bad burn with this coolant. It may be a wonderful coolant I do not know.

[28ACoupe]

Again, Looking at this from the wrong direction. The fact that it doesn't boil so fast is a good thing. It doesn't allow the vapor barrier to form between the cylinder walls and the liquid which ensures that there is actually liquid against the metal and not steam. This makes the cooling action of the coolant more efficient than standard coolant which leads to lower overall temps in the system.

Ponder this: With the Evans Coolant, IF, coolant reached 400 degrees in a COMPLETELY full engine, with NO air spaces, would it destroy the engine?

I don't know.

A modern car will operate as high as 220-230F while controlling the fans in the summer. I don't know how hot an engine can operate for prolonged times without harm assuming the oil doesn't burn. I have to assume the hotter it gets the more things expand and everything has a limit.

I'd like to hear opinions from others. My guess is 300F coolant temperatures would be hard on any engine but I have nothing to base this on. Modern cars try to keep the coolant temps around 220-230F or lower but I assume this is because most pressurized systems with coolant will boil around 260F.

MrTube,
I sure don't want to upset anyone with my opinion agin, But I will try one more time ,.... And this is "JMO".

Their will alwas be a new product out their that is going to solve all of our "A" model problems, Even if we dont have a problem .

This kinda reminds me of the ole snake oil salesman who rides into town in the old west in his covered wagon to sell his new Wonder Medicine that will cure any ailment.. "Guaranteed".

In my opin.... folks have been using water and anti-freeze for around 80+ years now, And it seem's to work ok.

Ever one should use what they think is best, Even if they buy it off a covered wagon .

Hey, Louis,
Don't worry about upsettin' someone with your opinions! We gotta' be independent thinkers, not just following around like a herd of GOATS. If some dislike what we say, they know where the "OFF" button is! (It's that round GREEN button on the upper right! and if any don't know your left from your right, I cain't help you!) Bill W.

What's the cost of this product?

[28ACoupe]

$43.95/gallon from Evans directly. However, it is likely cheaper from their dealers and you don't have to pay shipping.

Keep in mind, this is a Lifetime product. I.E. never have to mess with your coolant again.
