Sorry Deserhonda I wasn't trying to go against your suggestions, I think he should definetly start with checking fans and working back, checking hoses, etc.. I was saying that if the timing belt hasn't been done in a while it should be done anyway, and usually you replace the waterpump, etc, while your in there doing that, right?
I'd still put money on the waterpump 
Good luck copa708, if you are planning on doing your own work on a 210k car, I think you might want to purchase a service manual 
No need to be sorry my friend.. everyone is entitled to give opinions and opinions will differ ,,
I agree with you that if timing belt need to be done, replace the pump at same time .. but he says the fans do not work , so i want to help him fix that ,,,,,,Now he said that lower hose feels cool ,, if so , it could very well be the water pump fins worn and not circulating the coolant.. but he needs to chk the coolant level and the t-stat first ..

i just purchased a new timing belt because it makes a loud screeching sound... i also got the other belt incase it might be that one.
FYI - Timing belts don't make loud screeching sounds - the tensioner bearings could. But it's usually your drivebelts that do that.

Didnt you all say that there was a kit on ebay that you could buy with all the belts, bearings,etc... that he would need. This is probably his most cost efficient bet if hes hearing the screeching anyway right? Not quite sure just like the info my belts are way past due at 168K now and getting really worried!! hey if you all dont mind could you post that link for the kit? Thanks guys

I don't know the rules for posting ebay links on this forum, but if you have basic motor skills you just have to type in "Accord Timing belt Kit" in ebay search.. check it out.

i just replaced my thermostat and i'm sure the other one probably worked too. also i just put in new coolant, i drained the old one out and just put new coolant in there. so i guess it should be the water pump which i'd probably have to change anyways along with the timing belt. this is all fine and dandy as long as it fixes it... if not well then i guess it's probably due for fixing anyhow.

You are bleeding the air out using the screw on the top of the T-Stat housing, Right?
I don't think the car has to be running to do it. just park on level ground.

You mention the lower radiator hose is cool when the top one is hot? That is how it is supposed to be. If the lower hose is cool then the stat is opening and the pump is circulating the hot coolant to the top of the radiator - down through the radiator, to cool it, and back into the engine.
If the stat sticks shut - the engine temp gauge will rise quickly and, if not shut down, the coolant will boil out but, the radiator will feel cool as there is no circulation outside the engine.
The A/C fan is supposed to run whenever and as long as the the A/C dash control is turned ON and the fan control is in at least #1, (lo), position.
The standard fan will run when the radiator temperature calls for it and usually cycles on and off at idle or slower speeds but, rarely runs at speeds over 40 MPH unless it is really hot, accending a hill or pulling a load.
Another problem could be a highly restricted/contaminated radiator core. At idle - there is not sufficient coolant flow without higher pump force.

Radiator temperature? Is there a sensor in the radiator too? If there is I think that is just for when the car is off.
The fans are controlled using the temp switch on the t-stat housing while the car is running (has a green two wire plug). When you shut the car off, if the radiator temp is high the car will turn the fans on untill the radiator temp drops. That's what was happening in my case, the fans would always turn on after I turned my ignition off.

WOOOOO YOU ARE TOTALLY WRONG.......... first off ,when engine is at normal operating temp the lower radiator hose is supposed to feel hot,, not as hot as the top hose but HOT,,, if it is cool the t-stat is stuck CLOSED...when the t-stat opens it lets coolant that has been stroed in the block , circulate,, coolant then will go through radiator and that's where is gets cooled..
If the t-stat is stuck open , coolant in the block will not stay there long enough to get hot,, thus you got a temp gauge reading low.. or not enough heat from the vent ..
BOTH fans are supposed to run with a/c on,, or when coolant temp rwaches a certain temp , which is the setting temp for the fan switch,, when coolant temp r4eaches that , it will open the switch , switch will ground the realy and fans will kick on...
BOTH Fans should always cycle on and off wether you got the a/c on or not..
the reason that the fans do not run as much when you go faster or hwy speeds is because the fastr you go , the more air flow you get through the radiator , so it will cool the coolant down , thus you do not need the fans to cool the coolant down..
Yo copa have you tried anything at all that i have adviced you ?? man,,,,, you got to try to do some things , Noone can come over there and do it for you my friend ..
Also go to the post POOP LOAD OF INFORMATIONS ,, click on it, and go to overheating , read up , i twill make you understand better how the system works ...

i realize this, but i'm not an expert in this. opening my hood and looking at it won't help me much. if i knew what to look at then i'd stand a chance. but so far all i got is "maybe the wiring" or "maybe the water pump" or "maybe the thermostat" but i doubt it's the thermostat because i just replaced that 2 days ago.

Where are you located? You should probably have someone that does know what they are doing look at it, sorry to say.

Us techs do not have a crystal ball when it comes to diagnosing a car,, there are more than one thing that can cause a problem , that is why we have to diagnose and do the eliminating process.....
there is more than 1 thing that could make the fans not work...from a bad motor to a bad fuse, relay, t-stat, no coolant, radiator cap. coolant leak, fan switch, wiring .....being at this end i cannot surely say what your problem is for sure ,that is why i will not say,, replace this or that and it will fix it,, A good tech will diagnose the problem,and replace only what is needed and to do so there are some steps a tech must take....
that is why you got to do the work ,, BUT .............
Please do not get offended or insulted when i say this ,,But if you do not know the right hand from the left when it comes to cars, i think you should leave it to a pro.. take the car to a shop that specializes on Hondas ,,or the dealer .. ..........Also if you plan on working on your car you might want to invest in a service manual, buy the one from HELMINC.com

the switch that makes the fans come on when you turn the car off, is the one located at the end of the top radiator hose engine side..the one on the t-stat housing is to make the fans come on while engine is running
