"Antifreeze/coolant chemistries are different. Products that contain Organic Acid Technology (OAT) chemistry are NOT approved by Ford and DaimlerChrysler for HOAT/G-05 applications. Products using OAT chemistry may be damaging to cooling systems that specify Hybrid Organic Acid Technology (HOAT) chemistry based on OEM recommendations." per Valvoline (Zerex). In other words, don't use Dex-Cool.

HOAT. It'll say so on the jug if it is.

Correct. Beware, though, as the sales person may try to tell you that the Dexcool will be just fine. They will especially do that if they don't have HOAT in stock. If that happens, go elsewhere, even if it is a dealer.

$20 more for the correct coolant vs. $400 installed for a replacement for a plugged radiator from using Dexcool. Hmm. Lemme think about this.

I would just like to add my personal experience with Dex-cool. When I purchased my PT it had 30,000 miles and the previous owner had drained out the system and put in Dex-cool. At 66,000 miles I started to have my own overheating issues and after much time spent on troubleshooting I found out I had a plugged up radiator. Now I have performed all services on this PT since I got it and the only thing that explains the LARGE amount of crap found in the radiator was from the corrosion that was caused by the Dex-cool.

Now I no there are other things that can cause there to be junk in the coolant but I checked and there is no other damage.

I converted my 89 firebird to dex-cool, wanting to never ever have to do the water pump again and all. Within 40,000 miles, the whole radiator was completely clogged. I don't like dex-cool at all.

Zerex G-05 HOAT is available at the counter at Napa. Thats it. Used to be pepboys and autozone had it, but no longer.

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.
So basically is we dont use collant with Propylene Glycol we're ok basically? I use green prestone 50/50 prediluted. Says its safe to mix with any color coolant and safe for all cars.
