1993 Honda Accord, 4cyl - Engine temp rises when at idle. Top radiator hose is hot, bottom radiator hose barely warm. Is that a thermostat issue? How can I make sure before I try to replace?

    how high is the guage going? Do the radiator cooling fan(s) operate when the guage reaches about halfway?Coolant comes out of rad. back to engine from bottom hose , so I would hope it's cooler , otherwise your rad. is not working.Sounds like normal operation.

    Yes, after driving a while and then idling at a stop the temp gauge goes up just short of the red zone. Then when I take off again the needle moves back to the middle range. The radiator fan only goes on after I've stopped and turned the vehicle off.

    Coolant levels are full inside the radiator and the overflow.

    Ok, thanks Zip. So, doesn't sound like anyone thinks it's a thermostat issue?
