Re: Continued overheating issue

At idle possibly water pump has inadequate flow. A supplemental pump or high flow replacement may help out. Higher engine rpm would cause better flow from original pump simply due to the faster pump speed. Smaller pulley on pump may also help as it would overdrive the pump.
You have nothing to lose by trying a smaller pulley or installing a larger inlet tube (lower rad hose) or a supplemental pump.
