Cooling problem: Runs hot at cruising range,okay at idle.
Relaced water pump, impeller, gaskets. Back flushed thermostat openings and hoses. No help still runs hot. Can't find poppet valve could someone tell the exact location so that I can check this, maybe it does not have one? Getting flow thru the tell tell.
