<div class="moz-cite-prefix">The heat transfer of Evans is less than
water so theoretically one would need a bigger radiator to run at
the same temperature. Running at a higher temperature is no
problem at all though, I have run most of my cars on a thermostat
with a higher opening temperature. It runs more efficient that
way. The advice to run an engine without thermostat is of course
idiotic.<br>
I run my JH on 86°C instead of the standard 74°C (hot states) or
82°C. This gives a better cooling because of the higher delta T.
Standard blue/green coolant. The electric fan comes in around
around 98°C and switches of at around 92°C. No fixed fan. Even
with the higher engine output because of DellOrto's DHLA 45 there
are no issues.<br>
A warning! Do not use the red/purple coolant as it can ruin
gaskets/seals in older cars leaving you with coolant in the oil or
oil in the coolant.<br>

The waterless coolant does not cool as well, however it
does not boil either up to 180°C. It is also bloody
expensive as you do not only need the coolant but the prep
fluid as well. If you cooling system is OK steer clear
from it.<br>

<p class="MsoNormal">I've searched the archives looking
for any discussion regarding how often to change the
coolant in the BN7. If the answer is there...I missed
it. I'm running a 50/50 mix of antifreeze and tap
water and it tests o.k. as far as freeze protection.
This mix has been in the system for a number of
years. Does coolant "go bad" with age? Any thoughts
about the waterless coolant being sold on the market?</p>
