Prestone Univseral Anti-Freeze

[SurfGuitar141]

OK...so Chrysler says you "must" use the special red (HOAT) anti-freeze, but not one auto parts store around here sells it.....

I made a command decision to substitute that product with Prestone Universal 5 year / 150,000 mile anti-freeze. Prestone claims it's good for any make or model vehicle, and can be mixed with any color anti-freeze.....

So how critical is it that Chrysler vehicles use the red stuff......????

All Prestone coolants are OAT which is Dexacool.Don't do unless you want issues down the road like plugged radiators,intake gaskets eaten away,and a disolved water pump impeller.You also can not mix HOAT coolant and OAT coolant as it will cancel out any protection so you might as well just run straight water then.


You can go to a Ford dealership and get there Gold antifreeze which is also HOAT coolant or Napa and get(or order) Zerex GO5.

I got mine at NAPA. Check there.

Ditto even says this warning on the lable of Zerex GO5 HOAT that OAT is not the same and will damage a system made for HOAT.
Also as a side note you will want to use distiled water and not tap water in the mix.

Listen to Troy surf. Mixing Hoat with Oat aint going to float the boat, very well at all.
I would be immediately headed to a dealership and have a flush done on their machine and make it right again. My recent dealer flush was not very expensive and left my system totally clean and Hoat filled.
The system should be flushed every 5 years or sooner anyways.

 

[SurfGuitar141]

I didn't mix the 2, I flushed the system then used the Prestone Universal.....

 

[tommudd]

Looks like to me you may be doing a flush again real soon.

You don't have a Chrysler dealership in your area?:shrug:

I made the mistake of using Perstone crap in a pinch very shortly after buying our Heep and ended up needing a new water pump less than two weeks after pouring it into the expansion tank!
I just go to the dealership and buy HOAT from them. Doesn't cost more.

Okay, I do know the difference between coolants. And I also have a slight understanding of why some automakers use one verses the other... like what kind of metal it will come into contact with in the engine. My Buick used Dexcool originally and I flushed the entire system over and over, ran it clean with pure water, and flushed some more, then finally started running the regular green stuff without having any issues for years.

Would this type of thing not be a possibility with the Jeeps?

Only if you have a custom made waterpump without a plastic impeller and have the whole cooling system coated inside so the OAT coolant does not eat the gaskets.

Ugh, a plastic impeller? Small wonder... it would eat the crap out of that.

Yep and every aftermarket version is the same way also.

My aftermarket water pump had an aluminum impeller on it which was quite a surprise to me considering the factory pump was plastic.

Do tell. Which one is it?

It's not just the water pump you need to worry about.
