I have a 2004 Dodge Dakota 4.7 with a manual transmission and 230,000 miles. At highway speeds the coolant temperature is running high, more than half almost to 3/4. It only seems to do it during the heat of the day in Texas when it's 100 degrees. It doesn't seem to do it in the morning when it's cooler. Is this normal? Is there anything I should do? Thank you
It doesn't seem to do it in the morning when it's cooler. Is this normal?
No, not really. The engine temperature should remain consistent. The time of day or ambient temps shouldn't affect it. (normal temps meaning they don't reach some remarkable high & unprecedented number)
Several things can have a negative effect on the system's ability to cool the engine. Could be as simple as low fluid level or a bad radiator cap. Start simple and check the basic things first.
