Air pockets in radiator


Air can be purged. While your engine is cool remove radiator and reservoir caps. Place funnel in radiator. Turn heat to the highest position and start vehicle. Add coolant to radiator as needed while vehicle warms up. You should see bubbles coming out of radiator. Fill reservoir to between cold and hot fill lines. Replace caps when bubbling stops but before coolant temperature reaches normal operating temperature. Never remove the radiator cap until engine has fully cooled down.

I have a 2003 honda civic with a over heating problem maybe?. There are no leaks at all, replaced thermostat, pressure test, took it to honda, took it to little repair stations. No one can figure out the...


It could be a circulation problem as you insist,but you know the head gasket can also cause the same problem yes because the head gasket also has water holes on it .so when there is a bent or a cut on the gasket it can cause overheating.thank you

Can an empty coolant reservoir tank cause the temp gauge to rise to ''H'' without the 2003 civic actually overheating?


Yes! If the coolant level drops below the temperature sensor the steam that is generating in the system will cause the gauge to read incorrectly.

2003 Honda Civic runs hot when idling.


Check the cooling fan switch. It appears your auxiliary electric cooling fan isn't going on when at idle. and engine temp increases. While you are driving, air is being rammed thru your radiator as you cruise along, so it isn't overheating, at idle, that isn't happening, and the fan should go on as the temp goes up. When the ac is switched on, the fan is being signaled to operate due to the heavy ac load on the cooling system.

Fuel gauge


The problem is the fuel guage sending unit, this is in the fuel tank, it will have to be changed out.

96 honda civic lxi overheating.


The car is not overheating if the temp gauge goes up and down by turning the lights on and off.  The gauge is giving you bad information.   You can confirm this by starting the car from cold, sitting in the driveway, let the temp go to somewhere BEFORE normal operating temp, then turn on headlights and fan blower on high, watch the gauge, then turn them off.   If the gauge moves significantly from the electrical load, you probably have a short or a bad ground connection.  

You have a short circuit or bad wiring somewhere in the front half of the car.  I don't know what thermostat switch you have replaced ... but it's not the problem .. stop buying them.  
If you are the original owner, was there an accident that may have damaged some wiring?  If you bought the car second hand,  get a carfax and find out where the thing was hit ... concentrate your wiring trouble shooting in that area.

I think it is something OTHER than the temperature sending unit or the gauge
