I am like torvill from evidence cooling systems today we're going to convert
this rare 1959 ferrari to evidence waterless coolant
now the first question is why why are we going to do this well water or water
based schools have used to cool engines for over a hundred years for good
reasons
water transfers heat better than anything else but water has its
challenges it cause corrosion and it has its limitations
so first water's freezing point is too high and his boiling point is too low
with water is low boiling point you have the formation of water vapor or steam
and the system is under pressure
Evans protects at both ends of the temperature scale for - 40 degrees to
375 degrees
that's right Evans bholasar 375 degrees and that provides a huge safety margin
between the operating temperature and the boiling point and boiling and no
pressure with Evans waterless coolant will avoid the effects of corrosion and
electrolysis as well
so first it's important to purge the system of water and that means getting
all the old water-based school and out
so before we get started we want to make sure we have all the right equipment or
well prepared to do the job
so first thing we'll need is a lower high volume low pressure blower there's
a lot of different types that we can use that will do the job
we also will need our Evans high-performance wireless-n coolant so
we have enough product on hand to make sure we can fill the system
we also want to use the Evans prep fluid
this will do a good job of chasing that old water out and flushing the system
clean before we add the high-performance wireless-n collant now when we're done
we want to test for water content and the tools we can use for that are a
refractometer and that will help us to gauge the water content another means to
do that is using the test strips that will indicate by color with the water
percentages
the last thing we need to do is put a sticker on the radiator to prevent
anybody from mistakenly adding water afterwards we want to keep it waterless
yeah
here we are underneath is 1959 ferrari about the drain the system and i'm here
with peter lim borrow from Lombardo motor cars in Berlin connecticut now
before we raise the car we took off the radiator cap
so now we're going to open up the petcock here remove the coolant from the
radiator and then we're going to open up a blocked drain and move the coolant
from the block and once we've done that we're going to lower the car and blow
air through the system to remove all that coolant that's left behind
now that we've been to the radiator coolant it's time to FG empty the engine
block of : so in this car we've located the engine block drains here now it's
important to remember each card is different in the location of the block
trains may be in different places but once you locate and have access to them
it's a very important step to get the cool and out of the engine block
so now peter is going to put the radiator cap back on before he begins
blowing high volume air through the cooling system this will force all the
remaining cooling out through the radiator and through the block
yeah
ok now that Peter has completed blowing high volume air through the cooling
system and we've got that remaining coolant through the block and the
radiator and catch basins below
now it's time to button everything up put the hoses back with the black train
back and the petcock close it up and put the prep fluid in and run that through
the system
now we're going to fill the system with prep fluid flush parts of the cooling
system with any residual coolant
now it's important not to use water to flush the system so Peters taking the
radiator cap off and he's filling the system now with prep fluid and then
we're going to run the engine for about 10 or 15 minutes until it reaches
operating temperature with the thermostat open and then we'll know that
the prep fluid has circulated throughout the entire system
now that we've run prep fluid through the cooling system we open up the block
train to get the cooling out of the block and we open up the radiator to get
all remaining cooling out of the radiator and we blew high volume low
pressure air through the system to force out any remaining old coolant and the
prep fluid
now this is what the prep fluid look like going in and this is what it looked
like coming out just to demonstrate how important it is to use the prep fluid
and blow it all through to get all the old coolant and prep fluid out of the
system before adding the high-performance wireless-n :
after we fill the system with the Evans wireless : we're going to run it again
and let the thermostat open to temperature
just as we did before with the prep fluid and then after we let that run
we're going to test for water content to make sure we're below the three percent
level
now that we've completely filled the system and we let it run for about 15 or
20 minutes let it get up to temperature brought the car back in let it cool down
so now we can test for water content so we're going to take a little sample
right out here out of the radiator and use our refractometer to test
yeah
and we can see through looking at the refractometer that we're at 55.5 on the
brick scale which means we're at three tenths of a percent water which is well
below the three percent tolerance so that means it's a successful conversion
as an alternative to using a refractometer to test water contact we
can also use test strips
now we draw a small sample of evans waterless coolant from the radiator and
we're going to use the test strips to dip in there and then match up to the
corresponding color to indicate that we've got the correct water percentage
as you can see we're close to zero percent water by the color matching and
lastly once you put the radiator cap back on
will apply the Evans warning sticker on top of the radiator and that should
prevent anybody from adding water to the system
ok now that we've completed the successful conversion Evans waterless
coolant we know that this car is protected for the rest of its life
because Evans is a permanent coolant that will last the life of the engine
we want to remind you of a few things never work on a hot engine
please make sure that it's cool down all the way before removing the radiator cap
and please dispose of coolant properly responsibly and environmentally safe way
and also please refer to the written instructions before beginning your
conversion to Evans waterless coolant
thanks
yeah
ok
yeah
