Hi my name is brad i see you are haveing a problem and i think i might know the problem. if you have done all of that to your car and it still over heating you might have a blown head gasket one way to check is to pull your thermostat out and fill your coolant leaving the cap off then start you car let it rrun a few minutes and if you see bubbles the radiator its the head gasket even though you wont have coolant in your oil or out the tail pipe. if you check that and ther is no bubbles i have one other spot for you to check ( dont know if you have the 1.5 or 1.6 sohc ) but if you have the 1.6 sohc with the mpfi you should check on the throttle body at the idle air control valve(IAC) you will see two small line`s that have coolant some times on hondas with high millage the line will fill with crud and that can cause a problem.. if you have any other honda needs please let me know

My 1998 Honda Civic is overheating. It has plenty of water and oil. Can only go about 5 miles before white smoke starts and the temperature gauge starts to rise


look for bubbles in the radiator while the car is warming up (be careful of hot coolant spitting out of the cap) if there or little bubbles it could be a good indication of a blown head gasket or cracked head

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'd start by checking the head gasket. Engine misfiring when first started in the morning or extra dirty coolant might be an indication too.

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 CR-V; Hot temperature gauge


Kind of, it's over heating, probably do to a stuck thermostat in the closed position, have it replaced, and if you keep driving it with it hot like that, you can end up with serious engine problems.
