There is a thread on the 951 board about this as well, but since I am contemplating using this on my wife's 928, I thought I'd ask here. The car is an '82 and has new coolant hoses, water pump, thermostat, and I will be replacing the heater core shortly, so everything should be up to snuff, with the exception of the radiator (which I believe is original to the car). I don't have any issues aside from at stop idling when the car is hot, and that is because I haven't installed an aux fan in front of the radiator (it was missing when we got the car and has been on the "to-do" list ever since). I have perfect faith in the ability of the cooling system to work fine the way Porsche designed it, as long as it gets maintained, and I am pretty religious about doing so.

I think the main advantage of using Evans is the low pressure aspect, which should make things like the radiator and heater cores last a lot longer. The anti-corrosive benefit also sounds good.

If it lives up to its billing, Evans should be awesome stuff for a 928. The problem is, I have never heard of anyone doing so (and yes, I searched the forum). Anyone have any real life experience running it?

 

Anyone? I can't believe that the subject hasn't been addressed here before. With the cost of a replacement radiator being what it is, I would think someone would have at least considered it.

I guess I will give it a try and report back. Wish me luck!

 

I am pretty sure it has been done here, if you can not find a thread here, I know it has been over at the Corvette forum.

 

Twice the cost of Xerex G05 from what I Googled. reviews are apparently good from some of the forums that I referenced. it's a waterless coolant and there is also a racing version.

 

The second review here is a 928 owner.

 

It..works, but what problem is it solving that a good system shouldnt already have?

If I bought it, ya, I'd give it a 'good' review too, I didnt overheat...but..im not now.

 

As our cars age, things like the radiators and heater cores are going to start giving out. Running a low/no pressure system ought to help longevity considerably. Plus, there are some additional benefits, it's not corrosive like water based systems and it allows additional performance benefits, if you believe the literature. That's why I am asking, y'all do all sorts of mods, so I would have thought if there was something to this, some one here would have tried it.

 

How about..replace things that are 'starting to give out'.


Cuz..I dont see NPG making weak things better..they're still aging, still going out..

 

You do realize that pressure will accelerate a failure, right?

I'm not as well known on the 928 board as I am on other forums here, but I am fastitidous about replacing parts in the name of "preventive maintenance". That's not the issue here. I asked about this product to see if anyone had experience with it, not to receive trite answers. Evans may or may not be a valid option, but if you've ever replaced a $1000 radiator or done a heater core replacement, others might appreciate having an alternative.

 

Then..fix it.

NPG doesnt heal a failing item...the fail clock isnt stopping.


Age & Heat will fail plastic end tanks eventually..probably rather have it fail under pressure slowly (drip) before its weak enough to catastrophically do so.

Its thicker, pumps harder, costs more than mostly free water..it WORKS..but..it's not solving a problem that should be resolved via normal maintenance I dont think.


It's a great product..but I dont think you sleep any easier with it, than without it in 99.99999% of cars.


Maybe cats can drink it or something.

We ran it in our race car for some time, didnt solve what was clearly a marginal OEM cooling system no longer able to manage a 650Hp problem...we tried out the marketing..

I -have- had to do the $1000 radiator replacement (proper alum one), I have not had to do the HC, but..if its gonna go, its gonna go at this age. I doubt it's giving you much more time before the inevitable. [Mr. Anderson...]

 

It's Propolyne Glycol instead of Ethylene Glycol. Not sure of what this chemistry difference means, but what problem are we trying to solve? Old age?
I will continue to use manufacturer's recommended coolant in my new aluminum radiator, it works fine.

Anyone used this or any feedback on this type of product.

Recently discussed a few weeks ago & here: https://rennlist.com/forums/928-foru...eir-928-a.html

 

All that reading and no consensus !
From what I read it makes your motor run warmer and a thicker viscosity seems to be the downside. With my S/C I was looking for another option for the summer cooling issues.

 

i have been using it in my 951

been just fine, not running any warmer that i can tell

using the racing version, less viscosity

just more expensive initially, but is supposed to last

runs less pressure, easier on hoses; no corrosion as with water; i'll drain and reuse if necessary

until the manufacturer's recommended change interval- a couple more years at this point

don't think i will put in my 928 though--mainly due to the initial cost (which includes a special flush prior to use)
