While the "conventional" cooling system was explained, I was disappointed there was not a reference to the revamped cooling system designed for the Chevy 5.7L LT1 V8 (that debuted in 1992?). Much was made of the "gear-driven" water pump used on the LT1 at the time, whose purpose was to eliminate the constant uneven belt tension on water pumps, which caused water pump seals to fail. (And it apparently worked, because those water pump seal failures caused me more cooling system failures than all other causes combined, in the 1970's and 1980's GM cars I had. Starting with my first LT1, and continuing into LS1 and LS2 engines, no more water pump failures!) Also, the LT1 "reversed" the coolant flow through the system, claiming better efficiency. I guess I'm just surprised that those advances didn't warrant so much as a footnote, as they may have been as effective at strengthening cooling systems as the addition of coolant overflow reservoirs, which became standard in 1974 GM cars (and which may have saved many 1971-73 Chevy Vega aluminum engines from warping, had they debuted in 1971!).
