Just so you know(about coolants)

tjkj2002 · **Posted:** Sat Feb 09, 2008 10:22 pm

Ther was some discution on the KJ country board about the correct coolant to be used in our KJ's.The correct coolant is HOAT/GO5 coolant,not DEX-COOL(red),not eythlene glycol(green),and not that "universal" coolants(like Prestons).Follow this link---http://www.gohtsn.com/article_321.shtml----to a report from the NARP panel regarding the NAD(National Advertizing Department,part of the BBB) regarding Honeywell's(prestone/valvoline) claim that there OAT extended universal coolant is not so universal and can damage cooling systems in Crysler and Ford vehicles that are made for HOAT/GO5 coolants.

Just thought I would post so you all wouldn't get the wrong coolant and ruin your KJ.HOAT/GO5 coolant can be gotten at the dealer or ZEREX makes it,seen it at Advance Auto Parts,Checkers(Kragens),and Auto Zone(at least hear in CO).It's pricy,about $10.99-$11.99 a gallon.

Product Description
AMSOIL Antifreeze & Coolant (ANT) is formulated to provide benefits far beyond those found in today’s conventional antifreeze and coolant products. This revolutionary formulation provides maximum antifreeze and cooling protection in the most extreme temperatures and operating conditions. And unlike conventional ethylene glycol-based products, which are highly toxic and even fatal, AMSOIL Antifreeze & Coolant is formulated with propylene glycol. It is biodegradable and requires no special disposal costs or procedures in most areas. Above all, its low toxicity limits the threat to children, pets or wildlife.

AMSOIL Antifreeze & Coolant provides even greater benefits:

Lasts Longer
AMSOIL Antifreeze & Coolant contains a proprietary poly organic acid technology. It eliminates the need for supplemental coolant additives and recharging cooling systems. AMSOIL Antifreeze & Coolant provides extended service life in all gasoline and diesel vehicles. It can be used for seven years or 250,000 miles in passenger cars, light-duty trucks, vans and recreational vehicles. It lasts seven years or 750,000 miles in over-the-road diesel trucks. Also for motorcycles, ATVs, snowmobiles and closed marine applications. AMSOIL Antifreeze and Engine Coolant lasts longer than conventional products.

Compatible With Other Fluids
AMSOIL Antifreeze & Coolant is dyed neutral yellow and is compatible with all ethylene and propylene antifreeze and coolant formulations on the market, including DEX-Cool®, Sierra® and Zerex®. It is also compatible with fully formulated diesel anti-freezes and other organic acid technology (OAT) and hybrid organic acid technology (HOAT) formulations.

Stops Leaks
AMSOIL Antifreeze & Coolant adheres to metal. It self-seals hairline cracks in welds and seams to prevent leaks, without additional stop-leak products or fibrous materials.

Prevents Metallic Corrosion
Independent tests reveal AMSOIL Antifreeze & Engine Coolant surpassed standards for metallic corrosion. It plates metal to protect even when exposed to acids and salt spray. Standard allowances for loss in aluminum and solder are less than 60 mg. AMSOIL Antifreeze & Engine Coolant lost 0 mg in aluminum and less than 6 mg in solder.

Standards for iron, steel, copper and brass allow a maximum loss of less than 20 mg. AMSOIL Antifreeze & Engine Coolant never exceeded a 3 mg loss in any of those metals in a testing period that was run for 10 weeks, three weeks longer than required tests.

• Formulated for heavy duty and automotive applications

Didn't now that Amsoil decided to go the propylene glycol route,the worst type off coolant ever made,I expected better from Amsoil.Oh well not every company is perfect.

What are you talkin’ about Troy? :wink:

This stuff should work miracles by how expensive it is! :shock:

The newer improved Amsoil Coolant is its own breed.

It’s been a while since I’ve read the test data on it, they recently revised the product about two years ago, and now the stuff can be changed in intervals of 7 years or 250,000 miles in passenger cars and up to 750,000 mile intervals for over the road diesels, which is really cool.

At the time, they were the only company that had the poly organic acid technology, and as far as I know, they are still the only company that has this type of technology. I do remember that the new technology was the best “tested” anticorrosion coolant on the market (as tested by an independent lab) that bonded to various types of metal including aluminum keeping the radiator and other parts corrosion free. I had 247,000 miles on my Chevy Tahoe with the original radiator and Amsoil Coolant mixed with distilled water. As mentioned above, the coolant actually seals hairline cracks. Some of the original testing notes showed that the coolant also protected against liner pitting and was highly resistant to corrosion of aluminum, iron surfaces, and solder points. Like I said, it’s been a few years since I have read the tests results, but as far as I know, everybody that I know who is running it loves it!

< on the fence awaiting more info from Amsoil on HOAT/GO5 application. I am currently running it in my KJ's but if it turns out to Not be the best for the application I will switch to whatever IS best.

An Amsoil Rep here in PA told me to NOT use the Amsoil coolant in any Dodge, Chrysler, Jeep vehicle. He had used it in a Chrysler that he had & it ruined it. I really appreciated his honesty. He told me that the coolant is the only Mopar fluid he would use - otherwise, all Amsoil. That's what I've done. FYI

Wow, great information. I’ve never used the product in a Chrysler/Dodge/Jeep application. Although, I know several Dodge Cummins guys who run it. I’m on the Dodge Cummins forum a lot and there are many guys who are using it well into high mileage and are not noting problems. What is even more interesting is that Amsoil recommends the product for Chrysler/Dodge/Jeep vehicles and says that it is fully Universal. :shock:

In order to be universal, it has to meet or exceed each manufacturers requirements. I’ll give Amsoil Technical department a call tomorrow and find out the scoop. Maybe, just maybe, Troy is on to something. :wink:

Surely Troy doesn’t know what he’s talkin’ about, really, when is Troy every right? :lol:

If that stuff is bonding to the insides of the engine and radiator, what do you think its doing to the heat transfer of the radiator and engine?

Bonding was my poor word of choice, Amsoil says it “adheres” to metal. As you can see, the boiling point is 225° F at 60 percent mixture. The guys on the Cummins forum, based on their experience, have said that the Amsoil coolant keeps their trucks running cool. I’ve heard the same from the powerstroke and Duramax guys. I emphasize Dodge because the debate is whether or not it truly works in the newer Chrysler Products.

That's kinda a real poor number there.

HOAT/GO5 coolant has a boiling point of 265 degres at 50/50 mix,270 degres at 60/40 mix,and 276 degres at 70/30 mix.The freeze points are -34 degres at 50/50,-62 degres at 60/40,and -84 degres at 70/30.

Any coolant can go to 250,000 miles,or even 1.5 million miles.It's not the miles driven it's the length of time that it is your cooling system.Chances are you'll never make it past 6-7 years on any coolant from the fact the rubber raditor hoses will go bad before then as will the thermostat.

I know the US military would never use the Amsoil coolant,not for the cost but for the fact it does not have a high boiling point.The "up-armored" Hummers in use in Iraq and Afganistan have a normal engine temp of 230-240 degres,the Amsoil coolant would boil when the "old tech" ethylene glycol(the green stuff) is working better.

the boiling point increases by 40° to 45° F if a 15 psi radiator cap is used.

The best way to truly know whether or not any fluid or lubricant is working effectively is to have an analysis performed. In this case scenario, we are talking about having a coolant analysis performed. This method of assessment is the only way to fully know the condition of the coolant, the stability, and the duration. A analysis does the following:

Level I
The following tests monitor coolant maintenance levels to ensure proper engine metal protection, glycol levels for freeze and boil point control, nitrite for prime metal pitting protection and acidity for adequate corrosion protection:

Visual (color, oil and/or fuel contamination, magnetic/non-magnetic precipitation & odor)
pH
Glycol
Freeze Point
Boil Point
Nitrites
TDS (Total Dissolved Solids)
Specific Conductance
Foam
Carboxylic Acid (ELC only)

Level II
Level II testing monitors the corrosive attributes of the coolant itself - acidic or alkaline - in addition to metal movement - the corrosiveness of each metal affected. This level includes all Level I tests plus:

SCA # (Supplemental Coolant Additives)
Total Hardness
Corrosion Inhibitors - Iron, Copper, Aluminum, Lead, Tin, Zinc, Calcium, Magnesium, Phosphate, Borate, Molybdate, Silicate

Level III
Level III testing identifies possible sources of problems detected in testing levels I and II, such as combustion gas leaks, air contamination, electrical ground problems, localized over-heating, chemical breakdown or other contamination sources inside or outside the system. It includes all tests in Levels I and II plus:

Contaminants - Nitrites, Nitrates, Chlorides & Sulfates

Level IV
Level IV testing identifies the type and degree of degradation acid formation resulting from any cooling system problems identified by Level III testing. It includes all tests in Levels I, II and III plus:

Acetates
Formates
Glycolates
Oxylates

Wouldn't it just be easier to use either the MOPAR branded coolant or the G-05 Coolant. Both of which are specifically formulated for our vehicles. Thus there isn't a need to worry about what should or shouldn't be used in your cooling system.

I agree with both of you,that's why I started this post to make sure everyone knows the correct fluid to use and be safe.

I totally agree. On the flip-side, the MOPAR branded coolant or the G-05 coolant doesn’t necessary conclude that it is the most superior product for its application. For most people, it truly doesn’t matter. And I understand your point; if it comes from the factory is must be suitable, right? No disagreement there! There are a few people out there who simply want to make sure that whatever product is being used is simply the most efficient. Efficiently, by definition, is any product that has laboratory and real-world qualitative and quantitative data that proves its quality and effectiveness. Threads like this has nothing to do with arguing which product is better. Instead, these threads help educate each other and promote better choices. Even if Mopar branded coolant, engine oil, and transmission fluid were the chosen choice, they still should be monitored and changed at the first signs of wear and breakdown. Different driving styles, different environmental impact, and the individual differences in mechanical well-being produces different results. This is exactly why I take oil samples, because an oil analysis will show me what changes I need to make. Fun stuff! Now, if I could only find a good mounting place for a by-pass on the KJ, then I would be happy!

Great information Troy, I will add this thread to my KJ folder. By the time I need to change my coolant, I’m sure there will be new and improved stuff out on the market. Maybe we can get JJ to take a sample of his Amsoil Coolant and assess its effectiveness.
