I am having a problem locating antifreeze that is HOAT rated. I plan to change it later this year and havn't found it at any of the local parts and other stores in this area.

At one of the Oreally parts stores they have Fleet Charge and I was told that it is rated for the Cummins diesel and it does list several diesel engins. It does prevent cavatation but I could not find a rating on the jug.

I understand that Zerex makes the product but I can only find OAT rated.

Any suggestions other than going to Chrysler?

 

I found Zerex HOAT locally at Auto Zone.

 

The brand name is ZEREX GO5. It is yellow instead of orange. The composition is the same, however the dye is different.

 

Thanx guys,

I checked at Auto Zone, I'll keep looking.

 

Any large truck dealer (I/H, Pete,KW,Mack) should have plenty of it.

 

autozone- 10.00 bucks a gallon. it is in a gold container.

 

I searched all the local parts stores and finally found some @ Car Quest. It was not the 50/50 pre mixed though.

 

NAPA caries it in my neck of the woods.

 

I'll forgot about NAPA, the store is off the beaten track in my neck of the woods. I'll check there.

 

What about Amsoil's antifreeze?

 

Check your local farm and fleet storesl. Such as Runnings, Tractor Supply,
Everytime I visit one I buy a bottle of Zerek in the gold jug, since most of my parts stores are selling the non-hoat high mileage Prestone or Havoline Antifreeze. Just make sure you read the back of the bottle. I saw two different types of Zerek one was rate for the older non-hoat and the other was rated for Hoat.

I also bought Zerex G-05 at Autozone (ghettozone).

I just bought the full strength stuff and then got some distilled water from Walmart.

 

Zerex at Autozone also. Could not find it anywhere else!

 

Qoute from Manufactures web site.

"IAT, or Inorganic Additive Technology, is the traditional green coolant found in most older vehicles. This solution offers fast-acting corrosion protection, although the additives are quickly consumed, exposing the cooling system to possible corrosion problems if not changed regularly.
OAT, or Organic Acid Technology, is the formula found in DEX-COOLŽ, and is usually the antifreeze/coolant of choice for VW and many Japanese/Asian vehicles. This updated formula is engineered to offer long-life corrosion protection.
The downside of OAT is it is not compatible with other types of coolant (IAT and HOAT). In fact, Ford, DaimlerChrysler and others say not to use this type of coolant in their newer models.

HOAT, or Hybrid Organic Acid Technology, is found in newer Ford, Chrysler and Mercedes vehicles. Using the very best aspects of both IAT and OAT, HOAT is a very protective, long-life coolant.



Perhaps one of the most important aspects to look for when next shopping for antifreeze/coolant is approval from the maker of your car. Currently, there is no "one size fits all" solution that is approved for use in newer cars. And filling your cooling system with the wrong solution may result in serious adverse effects.
Products marked APPROVED have been subjected to years of field and lab testing by your car's manufacturer and are certain to provide the best performance and protection. Also, use of these products will ensure your car's warranty remains intact. The same cannot be said for using non-approved products, which may end up causing more problems than they solve. Some quality antifreeze/coolant producers even print the makes that have approved their products for use. This is always the best way to go."

Hope this helps
