[kelton]

Im sure you checked but do you have enough coolant?

[customchord]

Its most likely you temp gauge senor...it's the one wire sensor under you dizzy on the head. There like 12 buck from Napa.

[Bcozzi71]

yea check that ...you SHOULD have a code if that is the problem atleast i did

[jdm_accord_ex]

thanks alot guys. ya cause i know i wouldnt pass smog if they seenn that. but 12 bucks nt bad ill check it out

[benji]

Just to double check, you bled your system, correct? Using the nub on the thermostat?

Im having the same problem, i got my accord last year in the summer, i got the car with the overheating problem but it does not reach the H. i changed the thermostat and still the same, coolant is always full everytime i check ( never need to put any)
the needle stays a little past the middle at times but when i start to drive it goes back below the middle ... help ?? ...lol.... 180k auto

You all checked to see if your fans or working?

[Hondateck2010]

yes the fans is working. does both have to be on ? cause i thought the other one is for the A/C

[ex_style90]

Well something like that. Facing the car, the fan on the left is for the engine, and the fan on the right is for the radiator...

thats exactly how my car is.... i dont know what the problem is..

The Left fan is A/C the right fan is the radiator.

Do both fans run when you turn the A/C on?

[Cygnus]

The Left fan is A/C the right fan is the radiator.

Do both fans run when you turn the A/C on?

Both fans should turn on with the A/C Running. Passenger side fan is the main fan, driver side is the condensor fan. Easier for people to understand when you say driver/passenger rather than right or left because those are relative to perspective.

is i havent started it in 3 days and right when it stared up it shot straight up to hot

If it jumped straight up to full hot on the guage when you switched the ignition on, and there was no chance that there was any heat in the motor then the guage sender unit is grounding straight to earth, or there is an earthing short circuit in the wire from the guage to the sender unit.

It doesn't sound like the same problem at all. It may be fan related (i.e. fan not working, or coming on at too high a temp), but if it isn't then my bet is that your radiator is failing to radiate adequately. This could be from:

Internal scale build up in the rad

'Fin rot', the thin metal fins (black painted copper or bare aluminium) on the outside of the rad are slowly oxidising away, though it may not easily be visible because the black paint often holds it together, until you touch it and they crumble

The front of the rad could be blocked with debris impeding air flow through the core. This could also be debris in front of the air con radiator, blocking flow to the coolant rad behind.

To check if the problem is simply the rad not radding properly, try switching on the heater a fan when it gets hotter, the temp should drop.
