I was just wondering the same thing just popped into mind and your question came up I wrapped my cooling hoses and currently I just changed the spark plugs all of a sudden I have a engine code saying engine loop open, deleted it and then insufficient temperature came up so I thought it could be thermostat or IAT sensor maybe it is due to my hoses not being able to breathe not there is basically brand new everything in the car at this point although my fans don't come on as much as they should
