Just ordered it and in the mail. Weather should be turning here back to more pleasant temps in the next few weeks so I will do a flush and fill with the NPG+.

My only concern is what happens if there is still a tiny bit of water in the system?

Did you order their water flush kit?

I am now.

Thanks George!

One thing dose concern me though. I see that it is capable of handling much higher heat, but shouldn't the objective be more to lower the operating temps rather than just running a product that can handle higher temps?

The main selling points for me is the better warding off of hot spots and the steam prevention which are 99% of the causes for our HG issues.

Do tell me more. Never heard of this stuff.

+1 please, searching now...

Chris White has had several posts on this. The stuff is very slick if it leaks out but it does prevent hot spots and the cooling system can be run at a much lower pressure.

Please please please don't put this in a car you are taking on the track.
In fact, please think about replacing coolant with distilled water and a bottle of Redline Water Wetter if you are tracking your car.

Its not just 'the other guy' who might spin on your dropped coolant.
A coolant dump = your own personal skid pad generator!

Yes that is the objective, to have temps in a normal range. Evans wont work as a bandaid for a broken cooling system.

Not having hot spots, no steam, much lower pressure, and better lubrication is the reason I'm using it. It's slippery as hell once spilled. Check the rules if you race your car.

I agree. Seems that even if it runs a little hotter than just water/water wetter, the benefits far out weigh that issue.

If they are not in R&D yet, they def should consider making their own oil additive with this same technology.

I don't think you'll see much hotter temperatures. The Evans coolant is thicker. As long as your coolant system is up to spec, you shouldn't have any issues. I blew a cometic gasket. Whatever I can do to keep things running better, I'm game. My Duarmax uses it, and it's designed to last the life of your cooling system.

So Tood, did you ever switch to Evans? If so, any comments about it? Running cool enough? Blown any head gaskets since or have any overflow since?

+1 Interested in your experience as well.

Someone over on the bimmerforums used NPG+ in his 4.4l v8 e39 to convert to a zero pressure system (e39's are notorious for cooling system failures due to blow outs from fatigue and plastic parts).

I didn't know that! My e46 daily driver blew it's coolant tank like an over-filled balloon--made quite a pop when it blew.
