Ok. New & clean looking rad. Newer but old water pump New tstat New sending unit (supposed to match original in ohms/temp according to service manual/Mitchell) resurfaced & checked head & new gasket Flushed: heater, block/head, & rad. Rad & block wasn't too nasty. Heater hose had a turd in it. Heater had crap in it. Flushed clear. It throws heat now..... It will run hot @ idle or 2000rpm, just keeps creeping up;;. Verified with scanner that it is indeed getting over 230. Upper hose gets hot, so I know the tstat is opening. Heater works, so I would think the water pump is ok. Upper and lower radiator hoses are not discernably different temperatures. Thoughts? Ideas? Thinking of pulling the WP to check the impeller. If not, I'm at a loss.
