Bobby 3/22/2010Well the fan would still kick on to cool the engine even in the winter. The cooling fan can run after the engine is shut off to bring the tempereature of the engine down. Even if its cold outside the engine is going to get hot especially on highway trips when the engine is working harder. Sounds like it is operating fine. If the fan is staying on an excessive long time after the car is shut down and draining the battery then there could be a problem. But it is normal for the fan to kick on even in the cold to cool the engine. If you think its kicking on more than it normally does then maybe its worth checking the temp sensor, but again don't assume just because the weather is cooler the fan shouldn't be coming on thats solely determined by engine temperature and an engine gets hot and needs to be cooled even on the coldest days.
bluey1970 3/22/2010Thank you, makes sense. But this scenario has never presented itself in the 15 yrs I have owned the car. The temp gage stays exactly where it always has, and the car never runs hot - I am just overly keen to changes to a system that has been the same for many years.
the car has 223,000 miles and i was wondering if the sensors were malfunctioning. thanks again.
Bobby 3/22/2010223,00 miles has the engine ever been replaced or overhauled? the engine could be getting older and creating more heat. Have you replaced the thermostat recently that could be causing the engine to run hotter if that is sticking a bit. Just a couple things to think about. It could definately be a sensor too most likely temp sensor.
bluey1970 3/22/2010Yes, 223K miles is on the original engine. interestingly enough, i had the thermostat replaced last summer when the AC was repaired and converted to R134a. the car never got warm for several years before that - but after I had the thermostat replaced, i started having the kind of interior cabin heat i remember from a few years ago. the accord always heated up fast. perhaps the two are related? the engine temp gage is always in the same place, too.. thanks for your thoughts and comments.
