Good article.
My rule of thumb for cooling systems -
1 Your block and heads water passages are dirtier than you think.
2 Your radiator is dirtier than you think, and possibly fouled with rust/well water instead of distilled water.
Not sure if you read thru all the posts, especially my posts near the end,
My engine heads, intake are freshly rebuilt 1 month ago the break in oil was removed and I have changed oil already after already putting on 1K miles.
It doesn't have water but anti freeze along with wetter.
The rad (Be Cool type) is clean, been flushed, and not 2 full summer's use...
I'm hoping it's because I never placed a thermostat in the engine and it's a new (tight) still...
Only time will tell with the new 'stat installed.
Thanks.
