Re: Radiator hoses 1 Hot 1 Cold Help
How far did you drive? As long as the coolant temperature of the coolant which circulates the engine is within limits, i would not bother. You probably didn´t drive enough to have the thermostat to open. Or it opened just a bit, so that the hot coolant entered via the upper radiator hose, but the airflow through the radiator cooled the coolant that much, that it is much lower in temperature and didn´t heat the lower hose. But as said, as long as the engine coolant temperature is normal, you should be fine.
