What is your question?
Engine heats up in 8 to 10 minutes idleing, did not change thermostat yet because upper and lower hoses feel about the same temp I don’t hear any noises in engine, engine does not want to idle after heating up
What makes this problem better or worse?
Gets worse as engine runs
