I am really curious what running the evans coolant would do. Here is
their response when I asked about the cooling capacity of the
coolant vs. water:<br>
<br>
"water will better dissipate heat. That's a given, but the thing
about even a 50/50 mix, water will still create vapor barriers in
the motor due to the internal metal temps. Our coolant does not
allow the coolant to turn to steam pockets like water does. Ours
stays a liquid and pulls much more heat from internal metals, which
in turn, lowers internal temps. Our coolant does not generate
pressure as well. The only thing generating pressure in the system
is the water pump. So there is no wear on gaskets or seals as well
as the hoses are not subjected to the high pressure either. "<br>
<br>
So, it would seem that if you do not have the pressure cycling in
the cooling system, your components might last longer. Not having
steam pockets would be a plus. What would be interesting would be to
see what the coolant temp settles at with the Evans coolant, vs. the
traditional 50/50 mix. My guess is that it would be somewhat
higher. They do make a big point about needing to make sure that
there is no more than 3% water contamination in the coolant. It
might be a bit challenging getting to all the places to dry out your
Vanagon cooling system - so the initial fill might involve filling,
testing for contamination, and draining and refilling until you were
in the correct range.<br>

type="cite">That's what I found interesting about the video, and
the fact that there's no pressure build up, hence the hoses last
longer and the heads/water pump, too. I replaced all the cooling
system parts a couple of years ago, almost all, if not all the
plastic parts replaced with stainless steel or aluminum pieces.
Some people are using long life coolant in their vans, so why not
a "for life" one? A 5-gallon bucket might cost me $200.00,
contrary to thounsands to replace the heads, gaskets, hoses... it
kinda sorta makes sense to me. But what do I know, I've had my van
for almost fifteen years and driven about 140,000 miles with all
kinds of problems and issues, mostly due to ignorance, and/or not
doing a good job fixing something the first time. It's been said
that if it's not done right the first time for being in a hurry,
somehow there's always time to fix things a second or third time.
I think I haven't learned that lesson yet for some mysterious
reason.

".......we have seen this type of corrosion in steel head as
well as aluminum. The culprit is actually the acids that
form over time due to the electrolysis. Our coolant will
eliminate all the corrosion factors along with the
electrolysis. Our coolant is also phosphate free."<br>
