I don't remember seeing a reference to your vacuum method. Searched youtube
but didn't spot it. Can you provide a link?

>>>Well, there is an optimal temperature range for an engine. Ford says
it's 192 degrees, but just to be on the safe side I try to run mine around
180 degrees.
Water boils at 212F at sea level with no pressure. But the boiling point
goes down as the elevation goes up due to lower pressure. A radiator cap
adds positive pressure (13-16 lbs is optimal) which raises the boiling
point,
so that water will stay in liquid solution up to about 260F.
Once you pass the boiling point, very bad things happen. The water turns
to steam, the engine cools unevenly, heat is unable to escape, pressure
skyrockets as water turns to steam (a water droplet expands to 2500 times
its
size when turned to steam), the radiator cap vents and dumps water on the
ground, the heads can warp, head gaskets blow, water sprays everywhere, your
day
is done and your engine is cooked.
Note that modern cars are designed to run at hotter temps and it's
apparently quite common to see 230-240 degrees. I don't own anything
modern so
I'll stick with 180-200 thank you!
There is absolutely no reason for a Pantera to overheat. Most Panteras
that I've seen that were running hot, were doing so not because of any fault
with the system, but rather due to poor maintenance--the owner had not
properly bled the air out of the cooling system. Air is a terrible thing
to have
in your cooling system and will lead to all sorts of problems.
While it is possible to get perhaps 95% of the air out using conventional
bleeding techniques, a vacuum-based bleeder such as the one I demonstrated
on
Youtube a couple of weeks ago gets you close to 100% effective and is much
mo' bettah.
