Ok have an update.. so this morning I put in a thermostat, and temp sensor..day before yesterday flushed the radiator and washed out the coils..refilled with coolant..run under load ran for 8 mins then shut down. Same 3-3 overheat code.Using my IR gun both the upper and lower tank on the radiator were about 210-230 as you moved the gun across them.Upper radiator house 195-200, thermostat housing 165. Bottom radiator house 180. These temps where all at shut down. So now what? Take the radiator to a shop and have it acid dipped?
