(Note: If this message is repeated 3 times, I apologize, but it seems to
be tripping some editing process at the IML which prevents it going through.
I've removed the word which I think is causing the problem, we'll see if it
goes out this time!).
Whoa! If you are running pure coolant (which is usually just another word
meaning Anti-Freeze, by the way), something is goofy here. You should be
running a 50% or lower solution with water. Over 50% is a mistake, as the
effect of raising the boiling point reverses, and also the solution becomes
a much poorer heat conductor, and is too viscous in the bargain.
If a competent mechanic filled your system, you are probably all right, but
at least take it to a radiator shop and have him use his hygrometer to tell
you
what mix you have. If someone has put the new snake-oyl type
non-antifreeze "coolant" that some unscrupulous vendors are touting as a new
"scientific elixir" in your car, this may be your whole problem. If it were
my car, I'd drain the radiator, block and heaters, then flush with clean
pure water, and refill with a 30% solution of ethylene glycol anti-freeze
(the common green stuff) and 70% water, and see if that doesn't help your
problem.
Adding a coolant recovery system has no effect at all on the operating
temperature of your car, it merely catches any overflow and returns it to
the cooling system during cool-down. If you've noticed a difference, it
must be because it is now keeping your radiator full of fluid, whereas
previously, you must have been driving with a less than adequate fill level.
As long as the fins are covered in the top tank with the engine cold, your
system will be cooling as well as it can.
As far as cleaning out your system properly, as we said previously,
directions for this process are in the IML archives (I know, I wrote part of
them!).
