Ethylene Glycol (EG) is the most common base of antifreeze, be it the plain old silicated style, OAT or HOAT.

Propylene Glycol (PG) is the other choice of base for antifreeze be it the plain old silicated style, OAT or HOAT.

The biggest difference between the two is that PG is less toxic to animals and humans than EG, common brand of PG is Sierra, PG is used in the food industry, PG does not conduct heat quite as well as EG but the two are very close. PG costs more than EG. The base stock of anifreeze be it EG or PG makes up 95% of the antifreeze, it is the additive package that is different amoung the types of antifreeze.

All common antifreeze mixtures are a Water - Glycol mixture at a 1:1 ratio, be it EG or PG based.

Evans NPG+ waterless coolant is a nontoxic mixture of glycols, but uses no water so it does not develop the cavitation problems that water - glycol mixtures do. With the Evans waterless coolant you do not get the vapor boiling of water - glycol systems. However Evans coolant still contains a corrosion inhibitor package. One downside to Evans NPG+ coolant is that it is only recommended down to -20F to -30F, so extreme cold applications are a problem. Evans does benefit from being waterless, however, there is no current manufacture that recommends the use of Evans coolant and so the long term wide field use testing is not available. There are FTE members who use Evans NPG+ successfully and it has been benificial in high heat situations, just understand it does not meet warranty requirements.

 

What perfect timing

Just today I called the Evans Diesel Technical Support # 1-866-227-9963 and spoke with Tom very helpful . *** Also please note that TOM stated DO NOT modify your Ford factory coolant system in anyway other than flushing ---- NO drilling of hole in cap, etc this ONLY applies to HOT Rods and other high performance vehicles

I am getting ready to install Evans that I purchased thru Dieselsite.com --- Tom suggested that I drop on by NAPA and purchase their Coolant chemical flush treatment especially if the vehicle has the HIGH mileage cooloant in it today ---definitely must do Flush due to chemical reaction with the EVANS must get all of the High Mileage coolant flushed from system.

However for safty sake I am thinking of doing the chemical flush regardless what current coolant is in place -- Its factory coolant for certain only have 14K miles to date ( Follow instructions on Coolant flush bottle stated Tom ) ---- and do THREE complete flush get vehicle up to operating temp EACH time and make sure thermosate opens and cycles thru Header core etc .

Tom also advised any Ford owner with the 6.0 Diesel to proceed with Caution on installing EVANS in the year models that were having the head gasket issues being Evans has a low surface tension .... I informed Tom I had the 2006 F250 FX4 model year --- Tom still recommended I call Bob R and just double check

So I called Bob R of Dieselsite also today and was informed by Bob that my Model yr has the larger Head bolts that FORD updated due to all of the Head issues --- so I am OK with installing EVANS .

I didnt think to ask about how it affects warranty

Am I reading the previous posts that EVANS will void my existing factory warranty ?

All of the Technical data I was able to pull truly has EVANS with many benefits ---- refer to Evans web link for details http://www.evanscooling.com/index2.html

Lets keep this forum discussion going

I ready need to be certain of pros & cons so I / we may make educated choices best for long term life of our Trucks

Lots of warranty issues are started with YOUR dealer. It would be best to ask them first...some dealers are more mod lenient than others.

 

Bob R of Dieselsite is Incorrect. All 6.0 Motors have the Same Size head bolts. There was a revised/updated headgasket starting with the 05 motor. All 6.0 have the same ability to have head bolt failures do to the torque to yeild bolts that are used. There were a batch of 05 motors that did not have the head bolts torqued properly at the factory resulting in a high number of head gasket failures. The revised/updated headgaskets appear to hold better than the preivous headgaskets. All that being said Any 6.0 can experience head gasket problems or head problems (warping) tuned or stock.


Evans coolant does not meet the FMC requirement of WSS-M97B51-A1. This does not necessarily mean that Evans is bad. Evans did tell you however, that their product has a low surface tension (ie it will find small leaks & weaknesses easier). Using a non-approved product will in and of itself not necessarily Void the warranty. However, if a non-approved product causes damage you are on your own for the repair bill. As BPofMD stated alot of it is up to the dealer that does the repairs, unless FMC sends and engineer out to approve/dis-approve the repair, so it may or may not effect your warranty if you have any type of coolant system problem (ie water pump, radiator, EGR cooler, Oil cooler, heater core).

Here is a TSB about the use of propylend glycol coolants

You must weigh the pros & cons for yourself and decide what course of action you feel is best.

 

Here is a link to a huge amount of information on Evans and other coolant for the PSD
http://www.ford-trucks.com.com/archi...art=1&vc=1.htm

 

There's actually a couple different types of OATs. Dex-Cool is one type and uses 2-ethylhexanoic acid (2-EHA), and Rotella ELC is a totally different type. I wouldn't put Dex-Cool in my truck, but Rotella is okay. I haven't considered the Blue stuff, but I would imagine it's as good. We run generators with that stuff in it as well.

Here's a great page that breaks it down:
http://www.sancarlosradiator.com/antifreeze_coolant.htm

Another option is Final Charge, which is the same stuff as Rotella ELC:
http://www.finalcharge.com

 

Personally would not use any OAT coolant in any coolant system. The Rotella ELC is repackaged Texaco/Chevron/Delo ELC.

 

Great information guys. I'll have to read through this again tomorrow... errrr... today after I get some sleep...

 

I'm a little confused here and a search didn't yield a firm answer for me.

Went to WalMart intending to pickup 4 gallons of Valvoline Coolant that others had been saying they procured at WalMart and was equivilent to the Ford Gold.....

But all WalMart had was Prestone Extended Life. From the packaging it appears the coolant is yellow/gold in color and the packaging says "Prestone® Extended Life Antifreeze/Coolant is compatible with ANY antifreeze/ coolant – regardless of color – for use in ALL makes and models of cars and light duty trucks."

The guy at the counter confirmed that the Prestone Extended Life was the same as Ford Gold hence I picked up 4 gallons.

Now I'm wondering.....

Can anyone confirm for sure if I can / should use this coolant or not????

 

Check the back of the gallon for something stating it meets the FMC requirement of WSS-M97B51-A1. This is what Ford recommends for the 6.0. If it does not mention this, you might want to find one that does.

 

Not to change the subject, but to get clarification as to why some of you are installing "coolant filters" and WHERE do I get one? Is there an ideal place on the engine to install it? ...I'm interested in this because I've seen enough of you that have them.

Thanks.

...and I will be sure to change my anti-freeze out with a HOAT version.

 

I personally wouldn't touch the Prestone......its not worth the chance....go get the Motorcraft. Guys I'm not as smart as some of you but I learned a lesson the hard way about this antifreeze stuff in one of my International DT466e truck engines on a 02 IH rollback tow truck. Cost me a $12,000 engine from not putting the proper antifreeze in it and not checking with test strips. Engine block cavitation! It's not the ole days anymore....this stuff will drive you crazy but you better perk up to all this antifreeze tech talk......

 

Quick friendly follow-up

Please refer to electronic string of messages contained within for additional information

I have no special interest --- but after my research decided on EVANS NPG+ Waterless Engine Coolant REFER to following web link for more details Evans Cooling Systems - High Performance Engine Cooling and Power Production. --- YES it cost more than the Motorcraft or any other manufacturer but in my humble viewpoint it was worth it

Also installed the Coolant BYPASS filtration system offered by www.dieselsite.com

Hope this helps

HAPPY NEW YEAR to all

 

Went ahead and returned the Prestone... No need to take the risk......

Should have just went to the dealer and purchased Ford Coolant in the first place. I was out on the town shopping with the wife today.... WalMart didn't have gold coolant, neither did my local Shucks , nor Sears, nor AutoZone, nor PepBoys.....all of them, even when asked, said they only carried the so called universal antifreezes like Prestone's OAT or the GM DexColl.

Finally stopped at a larger Shucks downtown and was able to pick up 4 quarts of Zerteck G-05 for $14.95 a gallon.

Now comes the fun. Changing the collant this weekend. Biggest concern - disposing of all the old collant and water used to flush. Seems like thats going to be a heck of a lot of fluid to dispose of.

 

I purchased mine from dieselsite.com. It was a quick and easy install. I have pics in my gallery.
