I've heard nothing but good things about Evans Coolant. Like the idea of zero pressure cooling system and no water. My ole 7.3 is due for some cooling system work, (hoses thermostat etc) so why no put a forever coolant in a forever engine.

Is it hype? or the real deal? I'm leaning towards using it.

 

Sorry, I'm not an Evans fan. There are some who have had success using Evans in their diesel, but I wouldn't.

There have been enough bad experiences with Evans in 7.3's a few years back to solidify my opinion that it shouldn't be used in a 7.3L PSD no matter what Evans claims.

In my opinion if you're looking to upgrade, back-flush your engine as lined out in the thread I created here: Gooch's Coolant Flush Procedure and In-Depth Coolant Information and then refill with a heavy duty OAT Extended Life Coolant.

This, after having been in the cooling business for years, I can attest to it. Using the proper coolant and doing proper maintenance is key. Anything that is maintenance free is pure BS and might as well be snake oil.

 

I know they have reformulated and now have a Diesel specific HD coolant available. Could it be the product has changed since your observations?

Could you briefly outline the bad experiences you speak of? The reason I ask is because your the first person to say anything bad. Appreciate your response.

 

There were documented problems in a few different threads on other UBB forums, IIRC, it was PSN and FDP. Heck, one might have even been here at FTE, I can't remember (CRS Syndrome, sorry).

Also, how much would 8 gallons of Evans cost to purchase?

Stewart

 

In looking around, the cheapest I could find was $170 bucks shipped for a case (4 gallons) from Amazon. That means $360 bucks for 8 gallons.

For a little over $100 bucks, you can get 4 gallons of ELC which, after flushing the coolant system, will last you up to 7 years/750k miles, or 10 years/1 million miles with an extender depending on which brand you get.

Stewart

 

What does Evans offer you over a heavy duty OAT ELC, besides almost 4 times the cost, for however long you plan on owning your vehicle?

Stewart

 

Logic or cost does not apply in an automotive enthusiast forum. We spend money on crap that looks good and makes us feel better. It's a hobby.


Well they (Evans) make lots of claims just like any company selling something different that is purported to be "better".

Some of the claims make sense on the surface such as zero pressure cooling systems. Certainly hoses, water pumps, heater cores, radiators and leaks would be greatly reduced. No water ... so corrosion is gone. Boiling point is 375 deg so the coolant will still be able to transfer heat beyond the "over heat"and it never freezes solid and expands. Passes JD cavitation standard.... JD sells it and puts it in their tractors.

But if it has some unintended consequences that you or anyone else knows ... that's why I'm here asking. Seek to understand then to be understood. I'm just looking for more facts. Seems like the right thing to do.

...just sayin'

 

Never thought about using it in the truck but I use it in my KTM with no issues. It really helped during the hot races and I haven't noted any adverse effects on the aluminum or magnesium components.

 

Oh, I don't quite agree with that statement.

Ah, see, that's what I mean when I say I don't agree with your first statement.

We spend money on what we feel is logical (doesn't matter what others think), and if we can afford it, because it makes us feel better.

To prove my point, would you still be considering Evans if it cost more than $360 bucks? At what point does cost cause your logic to be applied? At $500? $800?

It's all a personal thing.

My point is, what is logical for me and you, may not be logical to someone else. That's why I asked you those questions. If spending $400 (+/-) dollars on coolant doesn't phase you when there's no appreciable, usable improvement (my subjective opinion, not necessarily yours or anyone elses) over what's already available, then I say go for it.

And yet according to Gooch, Ford specs state the water pump seal for the 7.3L PSD is made to seal and operate in a high pressure system. Does that mean it will fail in a low/no pressure system like Evans? No, I'm just pointing out a difference.

But not eliminated.

I've read where one Evans user (I believe the thread is here on FTE) had a couple leaks and lost coolant. By the time he got his issues sorted out, it had cost him a lot more money because of how much Evans coolant costs.

He got fed up and eventually ditched the Evans and went back to a pressurized coolant setup.

But don't let it get low due to a leak. One user lost his engine because the Evans got too low in his engine.

Yep, it does prevent cavitation. But just like a HD ELC, don't let it get low.

Shoot, you got me! I'm stopped in my tracks by the freaking cost so I never asked Gooch why he didn't like Evans for more reasons than he's posted.

I wish I could give you facts. All I can do is repeat what Gooch has stated and relate what I've seen posted by people who have used it, both good and bad.

For me, I'm as happy as a fart in a wind storm with a HD ELC and Evans cannot make me happier, so I'll stick with my Delo ELC.

Stewart

 

If the Evans coolant would eliminate the oil cooler from clogging up, then it would be one of the cheaper bulletproofing options for the 6.0 PSD.

 

If I run this in my 5.4 will I have the same HP and torque as you PSD guys? I'll just go ahead and order a few cases assuming yes I'll get some for the wife's 01 highlander too, that thing will be belchin black smoke in no time! Thanks guys!!!

 

As I research this product I've found only two camps... lovers and haters. I'm neither at this point. Like the idea but not all good ideas are worth a darn.

The guys who love it are those who really push the pedal hard (racers, truckers, boaters, farm equipment) or the automotive community who restores cars/trucks. Not all but a vast majority. I read one review from Canada where power went out and many vehicles lost their engine heaters in the dead of winter. Between freeze out plugs popping, leaks and engine cracks one guy said nothing happed to his engines.

The haters seem to be those who lost the coolant while driving (physical damaged to radiators etc.) and had to add water or those who didn't get all the water out of their existing system and the coolant turned nasty. There is also the ... what I'll call automotive accountants who compare cost to gain.

It's almost like the dino oil or synthetic's debate years ago. There appears to be good science and supporting tests for the Evans coolant. The real-life issues are subjective but important... and equally true.

Claims of increased fuel mileage seems overstated but fleet useage seems to bear this out. The old car restorers love it... actually swear by it, but again, automotive hobbiests and cost is not the biggest priority.

The reformulation of the product seems to be a result of the product issues at the user end, as a result of misapplication or incorrect usage. There are multiple products now, and some additional products to help prep the cooling system. In addition most vehicle owners do not anticipate cooling systems issues and therefore do not see the need. However I did read where those who had overheated previously or continue to overheat as a result of hauling in hot conditions or running severe grades in mountains, switched to Evans coolant and this group liked it the most.

*So far I've concluded the stuff is good for severe applications. Especially snowmobiles (extreme hot and cold) racers and heavy haulers.
*Efficiency claims are overstated.
*Cost is high but seems to pay back for fleet useage. Can be recovered and reused indefinetly.
*Will not turn to steam until 375 deg so it continues to transfer heat beyond what is typical for traditional coolants.
*Works best in vented cooling systems

I have not been able to find out what happens if it mixes with engine oil (head gasket failure) or if it gets into an automatic transmission.

So far most good or bad claims by users are anecdotal.

...just sayin'

 

Properly mixed antifreeze has almost no chance of freezing -74F to -84F depending on the brand. When temperatures start dropping below about -50F they don't turn off their equipment.

 

I totally agree, I have never seen any "lifetime liquid" that is worth it, in fact lifetime is just a sales gimmick that I never listen to. If you look at statistics you won't even have your truck as long as you may think...............WASTE!
