Modern OAT type coolant use in a Cub
Hello everyone. Any reason I shouldn’t switch from green IAT coolant to the newer OAT type coolants? Use premixed brand of red OAT in other machines and looking to simplify. Would definitely do a flush and fill to clear out system. Also the new coolants are supposed to be longer life. Just wondering if anyone is more knowledgeable about these newer coolants. Just don’t want to damage any of the metals in the Cubs system. Thanks in advance

IAT? OAT?
From my understanding many I know say the red dexcool is what makes the intake gaskets fail on cars!
I did a intake gasket on a 95 lumina for a neighbor, and after flushing we put the green stuff in!
My tractors will only get green antifreeze!
I am too cheap to use pre mixed stuff when I have basicly distilled water from our dehumidifier!
Good luck!

Re: Modern OAT type coolant use in a Cub
Thanks for posting that article, Don. I’ve been putting this off flushing for a while, and I will use the traditional green stuff with distilled water when spring arrives.

The red newer antifreeze will dissolve the soldered connections over time.
The radiator will be rendered into junk.

Re: Modern OAT type coolant use in a Cub
The ONLY thing that wears out in your antifreeze is the corrosion inhibitors. If you refresh those, you should never have a problem. (Caterpillar service training LONG time ago)
If I have a complete drain, I fill with 50/50, then do all my makeup with full strength. That by itself helps with fresh charge of corrosion inhibitors. You used to be able to buy corrosion inhibitors separately.

What's the source of that information?

Can you use Dex cool in older cars?
Dex-Cool IS NOT backward compatible. If you noticed ALL of the vehicles that it was put in from the factory DO NOT have any soldered components. Dex-Cool will literally eat the soldered welds on older (mostly copper) cooling components.
https://findanyanswer.com/can-you-use-d ... in-any-car
If you google “will newer antifreeze hurt older cars?”, and possibly change up the question a little to you’ll find more on this from different sources. Also the two different types of antifreezes don’t mix and gel up clogging passages . Most all of the newer antifreezes are similar to Dexcool being red in color.
I believe the changes were made in antifreeze to make them less toxic and also glycol was getting in short supply for a while with a major plant burning to the ground years back.
Manufacturers redesigned their cooling systems to be able to handle the new coolants.
It’s my understanding if the system is completely flushed you can use the older green coolant in a new system but not the other way around.

Re: Modern OAT type coolant use in a Cub
what hurts things is NOT changing your antifreeze, green should be done yearly, the chemicals break down and the slimey mess begins, it is ignored most of the time by most

Re: Modern OAT type coolant use in a Cub
This questions drew my interest, so I did a little research, in addition to Mike's and my links. This one from Hemmings probably answers the question best. Scroll down to the paragraph after the second photo for a good explanation.
https://www.hemmings.com/stories/2014/0 ... antifreeze
The bottom line is, don't use OAT or HOAT antifreeze in antique tractor or vehicle radiators.

Yup,prestone, easy to get, cheap and works so if it ain’t broke don’t fix it.
