Yes Brian, make sure the tubing will with stand the heat.

Subject: Antifreeze Enema

| I'm thinking out a method of replenishing the antifreeze without any
chance
| of introducing air.  I seem to waste a lot of coolant by adding into the
| expansion tank while the engine is running etc.  Any fluctuation in RPM
makes
| the fluid go all over the place, and trying to get the cap on at just the
| right moment is tough to do without introducing air.  Here is my intended
| method; (1) Make temp filler cap from spare pressure cap by removing
valvery.
| Install this on expansion tank. Attach length of clear tubing to temp
filler
| cap and the other end into container of undiluted antifreeze suspended
from
| ceiling or step ladder as high as practical above van. Start siphon by
| draining off some old coolant. Clamp off tubing. (2) incline van (3) drain
&
| flush using tee in heater hose method - mine is brass (4) remove bleeder
| screw in radiator (5) fill system with pure water through flushing tee at
low
| steady pressure, allowing stream to flow from bleeder. While this is going
| on, run van for few minutes at 2000 RPM with heater open to circulate
water &
| get rid of any air (6) Shut off van, water, cap tee, close bleeder screw.
(7)
| Unclamp tubing (8) Now you have an air-free cooling system of pure water.
All
| that remains to be done is to remove bleeder screw, which will start to
| siphon in pure antifreeze. As each unit of antifreeze siphons in, a unit
of
| water will be displaced by it and run out of radiator bleeder. Continue
until
| mixture is correct proportions. (9) install bleeder screw and pressure
cap.
| (10) Take drive (11) Check top of expansion tank for air, check
| concentration.
|
| Any thoughts?
