1993 Honda Accord Q&A

1993 Honda Accord Question: HOw can I check to see if my thermostat is working?

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? -
Answer 1
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. -
