I am just not willing to turn a blind eye to the manufacturer's recommendation on the basis of hearsay and wishful thinking.
|09-18-2012 04:21 PM|
Show me in writing.
I did just that several years ago with reference to a Cherokee. Zerex strongly advised that I stick with the the original IAT coolant. And their published advice still recommends the same.

You're entitled to your opinion though you should be aware that Valvoline/Zerex disagrees with you.
So aside from your obvious personal purpose in what you said, you really should call Valvoline who owns the Zerex brand and ask their tech support hotline for their advice where you will discover they disagree with your opinion. Here's the #... 800-832-6825. Valvoline/Zerex agrees with me that a good flush with fresh water first is all that is needed to convert an older Jeep to successfuly run G-05.
So it's fine if you disagree with me, I don't really care, but I recommend you finish your argument with Vavoline/Zerex and attempt to convince them they are wrong. Personally, I'll continue doing what Valvoline told me when I asked them years ago about converting my '97 TJ to run G-05.

Thanks Jerry.. i appreciate the help and info..

|tangofox007||According to Zerex, G-05 is not appropriate for TJ year models prior to 2001.|
|09-18-2012 11:17 AM|
Zerex G-05 is HOAT, works well in our Jeeps, and is generally widely available. That's the stuff I use in my TJ.
And Ragman, on your question about using Prestone, read the first paragraph in UnlimitedLJ04's post immediately above yours. I would not use Prestone for the reason he gave.
|09-18-2012 10:35 AM|
alot of info there.. if doing a complete flush on a 2006 that requires the HOAT..
what would be recommended.. i was told by some that i should just use the prestone 50/50 and not the orange dex cool cause it eats the seals up???
going to completelty flush out the system and change the hoses when doing this..

John Deere, Mercedes, Ford, Chrysler and a bunch of other companies use HOAT from the factory now. GM, and a few other companies, uses OAT (Dex-Cool) from the factory now. IAT is old school "green" everybody is familiar with. If you search online a bit, you'll also find lots of people unhappy with Dex-Cool stuff, even in GM products...
The primary difference between IAT and OAT or HOAT is the anti-corrosion chemicals, not the glycol itself. All antifreeze has chemicals that help resist corrosion in your engine, radiator and cooling system. Those chemicals have a specific lifetime and compatibility. IAT lasts maybe 1-2 yrs, which is why you were always told to flush your coolant every year "back in the day". From an environmental perspective, that's stupid...because you get people dumping poisonous antifreeze in their backyard or down the drain, and contaminating the drinking water supply and killing animals. Also, people that don't know jack squat about vehicle maintenance just leave the antifreeze in there for 10 yrs, then wonder why their vehicle starts overheating and the radiator is leaking/clogged with junk & rust...and you get more environmental impact as antifreeze goes everywhere on the side of the road. So to reduce the environmental impact and maintenance requirements, they developed new, better chemistry. These last ~100k miles and ~5-6 years, depending on the application...but the main idea is you change the fluid less often, you get better corrosion protection and your cooling system lasts longer.
Also remember antifreeze color is IRRELEVANT. It's just a dye...antifreeze can be any color they make it. So you can't use color as a gauge for whether it's IAT, OAT or HOAT. Get what's spec'ed for your vehicle and don't mix the types and you'll be fine.
Here's some reading on the subject: http://www.search-autoparts.com/sear...27/article.pdf
Here's an example from that article:

|Trailblazer||Thanks for the heads up guys on the Dex-Cool i thought that was for GM products only,but was'nt sure.You guys are awesome!|
|04-04-2012 08:03 PM|
|Jerry Bransford||Definitely avoid Dexcool. That stuff, as already said above, is bad news. And while I'm a big fan of Zerex G-05, I'm not sure if it is compatible with what is in there now. I probably wouldn't add G-05 without doing a complete drain and flush first. For now, I'd top it off with nothing but distilled water until you can do a complete drain and flush. Not tap water, distilled water. Water cools better than coolant does anyway.|
|04-04-2012 08:00 PM|
use Zerex GO5, it's half that price and is Chrysler approved.
whatever you do, get an approved HOAT antifreeze...do NOT use Dex-Cool.
|04-04-2012 07:56 PM|
You could use the "mixes with any type" coolant. BUT and It's a big one.
If your jeep is still under factory warranty, use what they say, and keep the receipt.
Don't give them an out if you have a coolant related failure down the road.
|04-04-2012 07:52 PM|
|DevilDogDoc||Use the Mopar stuff or Zerex GO-5. Those are the only ones approved for use. Penny wise pound foolish right, you will cause cooling issues in the future if you add Dexcool. Now if you totally flush the system multiple times you can run the old school green, but by the time you flush and fill with that you have spent more than the 25 the Mopar stuff runs.|
|04-04-2012 07:29 PM|
Dex-Cool is bad for any vehicle..just ask anyone who has done intake gaskets, heater core replacements, radiators, etc on a Dex-Cool system. That stuff will gel and eat gaskets and such if to much air is allowed in (low coolant level) or if its improperly mixed with water...
The easiest thing and cheapest would be to add a generic coolant that can be mixed with all others, although it will probably be green in color.

That much for engine coolant?
I was checking the fluids in my jeep yesterday and noticed that the engine coolant was a little low,so i called the local jeep dealership to ask what kind of coolant the '06 tj uses.Well she tells me it uses the Mopar premium pink,so i ask her the price and she say's $24.95.Seeing that i hate to pay that much and to me it looks like the Dex-Cool.Can i use the Dex-Cool instead,or is it a totally different coolant?
