I have a 2005 Honda accord 4cylinder with about 243k miles. I was in dead stop traffic last night for a good 45-50 mins and the temperature gauge starting going very close to the max temp. I did a quick google and put the car into neutral and revved it at about 1500rpm to reduce the heat (which brought it down significantly). After getting home I went to check the car thinking the radiator fans went out but both are still running fine. Oddly enough, my coolant seems extremely low for refilling it 4-5 months back.. I was trying to track down a leakage point but couldn’t quite identify one yet. Not sure if anyone might think it might be due to something else.. I did take some photos of possible leakage spots…. Thanks guys!
