Antifreeze?

Gaze · Oct 12, 2008

Saw I was a little low today so I went to top it off, but the cap said to read the manual. The manual makes the following claim:

The recommended mixture is 50/50 ethylene-glycol and low mineral content water. Never use pure antifreeze. Only Mopar Antifreeze Coolant, 5 Year/100,000 Mile Formula (glycol base coolant with corrosion inhibitors called HOAT) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% distilled water.

CAUTION: Mopar Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769) may not be mixed with any other type of antifreeze. Mixing of coolants other than specified (non-HOAT or other HOAT), may result in engine damage that may not be covered under the new vehicle warranty, and decreased corrosion protection.

I dropped by wallmart to take a look for the stuff since they carry a lot of Mopar branded fluids.. no luck. Has anyone else filled with another type of antifreeze? Anyone know where (other than the dealer) to pick up the HOAT stuff?

you must stick with the same colour.

if its green use green and red use red. the blue stuff is cheap and fairly crap. red and green have different properties so alloy engines don't corrode for example. red is normally made by basf and is usually the best 5 year stuff. i'm sure lots of make will do the proper stuff.

this: http://www.commaoil.com/ go to products..coolant...red

give you an idea of different ones available from just 1 manufacturer.

Walmart, Autozone, Pep Boys, and Advance Auto... none of them had what I needed.

Went to my Jeep dealer and a gallon of it cost me $21.50. It's a non dilluted mix, so I should be good for a while.

Use caution when selecting coolant...

See full excerpt from the manual:

Selection Of Coolant
Use only the manufacturers recommended coolant, refer to “ Fluids, Lubricants and Genuine Parts” for correct coolant type.

CAUTION
Mixing of coolants other than specified Hybrid Organic Additive Technology (HOAT) engine coolants, may result in engine damage and may decrease
corrosion protection. If a non-HOAT coolant is introduced into the cooling system in an emergency, it should be replaced with the specified coolant as soon as possible.

Do not use plain water alone or alcohol base engine coolant (antifreeze) products. Do not use additional rust inhibitors or antirust products, as they may not be compatible with the radiator engine coolant and may plug the radiator. This vehicle has not been designed for use with Propylene Glycol based coolants. Use of Propylene Glycol based coolants is not recommended.

Adding Coolant
Your vehicle has been built with an improved engine coolant that allows extended maintenance intervals. This coolant can be used up to 5 Years or 100,000 miles before replacement. To prevent reducing this extended maintenance period, it is important that you use the same coolant throughout the life of your vehicle. Please review these recommendations for using Hybrid Organic Additive Technology (HOAT) coolant.

When adding coolant, a minimum solution of 50% recommended Mopar Antifreeze/ Coolant 5 Year/100,000 Mile Formula HOAT (Hybrid Organic Additive Technology), or equivalent, in water should be used. Use higher concentrations (not to exceed 70%) if temperatures below 237°C are anticipated. Use only high purity water such as distilled or deionized water when mixing the water/engine coolant solution.

The use of lower quality water will reduce the amount of corrosion protection in the engine cooling system. Please note that it is the owner’s responsibility to maintain the proper level of protection against freezing according to the temperatures occurring in the area where the vehicle is operated.

NOTE: Mixing coolant types will decrease the life of the engine coolant and will require more frequent coolant changes.

Mopart Antifreeze/Coolant 5 Year/100,000 Miles Formula 6.8 Liters is recommended

This post is one of the great reasons why I joined this forum. I would have just grabbed any old antifreeze. Thanks everyone for the information.

Good to know! Thanks!

I wrote to Prestone concerning the use of their "multi/mix with anything" antifreeze, and it's use in my PT cruiser. The answer was, yes, you can mix it. You can also use the hydrometer to check the freeze point. There is a concern about the pH of the mix, and how often to check it. Anyway, I've used the Prestone stuff for 3 years withiut any trouble. You may want to contact them about using it in the Patriot. I will, when it's time to do mine, in case anything has changed.

The colors are marketing gimmicks designed to make you think you need the same color and pay more. Read the statement and warranty on a bottle of Prestone (other generic brands have it too).

Welcome to the site! I hate to start off on the wrong foot, and I'm sorry for using a political term, but your post borders on misinformation. Using a non-compatible anti-freeze, even after a flush unless it's thorough, may have horrific results. It may react even with a small amount of the old coolant, and turn to gum, plugging up the entire coolant system, not only the radiator. There's at least one such tale of woe on this site. Anyone dong this, use extreme caution!

Quote from The Family Handyman: The Difference Between Green and Orange Antifreeze
It’s never a good idea to mix two different colors or types of antifreeze. Mixing two formulas won’t cause any dangerous reactions or explosions, but it could turn your coolant into a sludgy chemical mixture that won’t be able to flow properly through your cooling system. Coolant needs to be fluid in order to do its job, and a thick coolant could clog up the cooling systems, leading to other potential issues in your vehicle’s engine. The bottom line? Don’t mix different colors of antifreeze.
