    Hi am a big honda fan , i have had 3 rover coupe tomcat , honda engine models , i have had 4 Civics , and this is my second accord ,i always had honda cars , for the last 12 years , i have never had any problems with them , my accord has now started to play up a bit , just a few days ago started to overheat , now can't figure out the problem , the fan does not come on when the temp rises past half mark , and i have tested the fan with a jumper and it does work just not coming on when the car heats up , and there is no leaks , and 1st thing i did was replace the fan switch , hasnt made a difference , i checked the relay and all fuses everything electrical is fine , hope someone can help me out , i have bought a thermostat i will try and fit it on tommorow ,i have attached an image on my engine bay if anyone wants to have a look , cheers

    Oil leaks on the dizzy would suggest overheating and seals perishing. the thermostat will one possibility or a clogged radiator core.

    If you take the fan switch connector off and bridge the two pins together does the fan come on then ?

    That's odd then that it doesn't on automatically. Maybe new switch is also faulty ?

    Did you get round to changing the thermostat ? Has it made any difference ?

    yes i was thinking the new fan switch may also be faulty , and i havent changed the thermostat i spoke to my mechanic friend he says its definitely not the thermostat when he checked it last one of the hoses was cold and one hot, so he told me to take it down to him tomorrow so he can test the switches ,

    one thing i should mention is i hear a faint beep from the engine bay , when the car is running when you open the bonnet ,

    What makes you think the car is overheating as you say there are no leaks and the gauge is only half way?
    If the car has been running for a while and is up to operating temp the top and bottom hoses should be hot indicating the system is cycling normally if the bottom hose is cool or cold then the thermostat is not regulating the coolant..

    Thank you , and does overheat it goes past the half mark shooting up , but i usually stop the engine before it gets too hot , the smaller hose that goes to the thermostat is the one that stays cold and the top hose the bigger one usually gets hot ,although my mechanic has told me the thermostat is fine , he did his checks , either way i will get the thermostat changed tomorrow just to get that off my list of suspects .

    From that it would sound like thermostat is at fault.

    You can do a resistance check on it as engine warms up, the resistance should go down. With engine up to temp the resistance should be close to 0 ohms.

    What you are looking for is very hot at the top of the rad and hot at the bottom of the rad although cooler than the top, gen on most cars you have trouble holding onto the top hose but you can normally hold the bottom hose , this proves the coolant is circulating and the rad is doing its job,if this is not the case something is blocking the circulation 90 percent the thermostat.
    Some fan switches work on a open circuit ,ie when you pull the connector off the fan will run,some work on a closed circuit ie the switch connects the circuit at a specific temperature.
    The sensor for the gauge and the fan can be separate so don't be fooled ,maybe the gauge sensor is playing up and giving a false gauge reading.
    You need to correctly assetain if it is actually overheating before you delve to deep.

    Hello and welcome.

    I have had in the past a car overheat because the radiator cap was not sealing properly, this means that the boiling point is lower (as system in not pressurised correctly) which causes the car to over heat. Cheap and easy fix if it's that and cheap try if not.

    so today i finally got the chance to get under the hood again , i was about to start replacing the thermostat , i decided to check the antifreeze in the car , and i was shocked to see it was all gone and i only filled it up a week ago , at my mates garage , because it wasnt leaking immediately we crossed that off the list , so now its come to light there is a leak , so i thought ill deal with that first , and if that sorts it , it should , then i won't need to replace the thermostat , or maybe i will because i bought it already , i want to ask for some advice , shall i use those coolant sealers , like k seal? are they any good , from my guess it most likely leaking from the heater matrix , or the core , i don't think it leaks from the water pump , any help and advice will be appreciated ,
