I guess I was late in not inventing this by-pass thermostat as MB DOC is saying benz has, I have thought of this for years!!!
Why not have another pump that circulated water after it shut the engine down?. I am glad benz is doing it, but on what engines?
As to the Red-Line Water treatment, I know and have read where guys whom have re-built some high horsepower engines, (muscle car engines, not benz's
,) like 426 Hemi's whom have had higher than normal temp readings after the re-build, and doing all the tricks possible, like aluminum rads, high flow pumps, have used this product and have seen a decrease in temps.
