question on cooling system

[Xwiredtva]

This is why your supposed to flush and fill every 24000 miles or 2 yrs.
Depending on how you drive, where, and how hard you are on the engine do it
more frequently. In a recent rebuild on a Suzuki engine before we even
started we flushed the oil and coolant with appropriate chemicals. This made
it very easy to work on. Once you get it back together, be sure to clean it
out, flush and fill in 5000 miles then every 24000 afterwards. Also I seem
to be the only one on the Suzuki list that doesn't have overheating problems
with my setup, in fact I have underheating symptoms...Makes ya wonder...Also
I've heard of people porting out the coolant routes in the block to increase
the amount of fluid flowing through certain areas, not sure if that works??

this may sound crazy but I thought I'd ask.

question, in working on my Chevy 350 block, (valve job), I noticed that my
cooling system, (heater core, block) is not pristine. in accidentally
finding some heavy hydraulic web sites, I wondered if anyone has ever
thought of some kind of filter in the heater hoses to trap rust, scale, etc,
rather than letting it flow through the system.

some of the stuff I've seen on the web, (not automotive), has been real
impressive looking, at the very least one might use a patch of clear tubing
and visually see the color/flow/ air content of the coolant, might be
interesting.

thanks, Ted.
