First post & First time Honda owner.

My engine fan is not working even with the AC or Defrost turned on. Further, I only have heat at idle. When I start to drive the temp. gague drops to cool and there is no heat. When I stop the idle surges a little then evens out and the temp. gague begins to show warming.

The engine has never overheated. I left the radiator cap off tonight to burp the system. The blower motor works fine. At idle, the cooling system seems to flow well.

I am stumped. I will change the thermostat tomorrow but I don't think that is the problem. What controls the fan?

 

the thermostat is probably your problem, Fans dont always kickin till the engine gets to a certain temp. If the thermostat is bad then the engine will never stop coolin itself to let the temp build up, then the fan wont come on.

 

i have that problem, during winter my temp will raise then i take off and my temp drops.. and if i turn off the blower it starts warming again

 

Had this problem last winter. Here's a link to that thread.

I found later that my fan doesn't even work anyway. I have been driving over a year with out a working cooling fan with no over heating problems what so ever. I live in florida where its 90+ in the summer in traffic. I figured if I've gone this long with out one. Why fix it. Honda put an oversized aluminum radiator in the 4g accords and the engine in mostly aluminum anyway.

 

maybe i should change mine... i have had it sitting on a desk for over a year now
