Well, it appears finally corrected, resolved. Took it back to original dealer, they found it needed a new water pump housing, something about the original one may look good but its not(warped??). Replaced that and its all good now. Good water flow from the discharge(tell tale) and not scalding hot water, exhaust cover it not hot even after a hard run at 3/4 throttle or more, and it can idle for long periods of time with out any overheat alarm at any time.
