i guys, i have a 6cyl ED. Lately if i drive it around for a while in the middle of the day( or whenever its stinking hot) it runs cold enough, but if i turn it off, then get back into not long after, the temp gauge is way up and doesn't come down again till i start driving and it gets some airflow going into it. Whats the go there, is it a blocked radiator or is this just what happens normally? I haven't noticed this prob at night or in the cooler months tho. Thx for any help
It's normal for your temp guage to go high after you switch your motor off. There are 2 reasons for this. Firstly when you turn your motor off, the water stops flowing. So the water that is in the motor heats up hotter then normal. Secondly hot water like hot air rises, and where the temp sensor is located is one of the highest points in your engine meaning the hottest water in your engine will end up there.
