superior engine coolant

[silvertdi]

anyone try the Evans NPG+ coolant?  I've heard good things, wondered if anyone has tried it in the VW community.  Thanks.

I haven't tried it but was seriously considering it until recently.  I just read an article about a week ago where a race car caught fire because of coolant that was the same type as evans.  I'll see if I can find it.  Apparently under normal circumstances it is relatively stable but becomes quite flammable when heated and spilled onto something hot.

That's exactly what happened to the race car.  It was a turbocharged application and the car had a coolant leak.  Some of the hot coolant sprayed onto the turbo and the car burst into flames.  I don't know what regular coolant would do in this circumstance but it does sound kind of scary.  :shock:

Here is the article.  I'm not trying to put you off but it is certainly something to be aware of.

Normal coolant will do the same thing.  In fact I had a rabbit diesel that burned down due to a do gooder throwing some antifreeze onto my melting airbox. (why my engine caught fire I will never know.)

I've run it for several years now, and would NEVER switch back. I'm sure it saved me during this episode as well as others where I had fan problems. Also, you will never have corrosion problems with it, and since you can run an open system, you will never have a hose burst from pressure.

Thanks jimfoo.  That's what I was curious about.  You summed it up for me.

what is the life expectancy for this coolant? 5 years? unlimited???

[silvertdi]

Pretty much forever.  The vendor states 500,000 miles.

wow... their site has way too much stuff!! what do i really need?

NPG+
NPG-
PREP FLUID

is their prep fluid really necessary or can i just flush out whats in there now really well?  difference between NPG+ and NPG-?  Jimfoo what did you do?  i remember reading that you let your system run open...

well i want to dig this thread up, because of my heater core blowing on me, and i was going to put off the coolant system flush & fill (with VW coolant) until the summer, but i thought why not just get it over with now.

i guess this question is more directed to jimfoo, but what were the steps involved to run this coolant?  from what i read on their site it seems like the NPG+ is what we need for our diesels.  i'm assuming that their prep fluid is required, but do I need to buy two gallons of it?  things are getting quite pricey at that point...

also reading their FAQ it seems as though some cars need higher flow for the coolant to work properly?  hmmm  this all seems to be very complicated... without definitive answers i'm probably going to stick with either G12 or prestone orange long life.  (and save big bucks)  although the zero coolant pressure (or very low pressure) is very appealing to me, as it would probably mean no more cooling issues (no more blown heater cores!!!)  :lol:

thanks

Flammable coolant. Hummmm.

Sorry, a bit late on the reply. NPG+ is what you want. The purpose of the prep fluid is only to remove all traces of water. If you can be sure you get it all out any other way, you don't need it. I haven't had any problems with it because of the viscosity that I can tell. It does run a little warmer, but that isn't a problem. I still have mine in, and have just gotten back on the road after my turbo problem back in December, and clutch problem.
I still recommend it.
