Default My 2001 Honda ex is over heating?

There is no leaks, it's not the heater core, it's not the thermostat, it's not the hoses and it's not the radiator cap.

All my anti freeze goes into my reserve tank and then never comes back out. Because it don't come back out of the reserve it overheats and then the fluid in the reserve blows out the top.

I quit putting fluid in the reserve and added to the radiator. And when I look 2 days later my reserve is filled to the brim and my radiator is empty and then it overheats and blows out the top of the reserve. I want to try and get ideas of what it could be here before I go and spend lot's of money. I have heard that it could be a warped reserve tank. Any ideas?

and I have already flushed the radiator out.

All fans are working properly! One answer said I was losing water from the water pump, but my question to you is wouldn't I see a leak on the ground?

Bleed the air out of the system. There is a bleeder valve on or next to the thermostat housing. Fill it cold and when you feel the upper hose get hot, open the valve a little until you don't have anymore bubbles, just fluid coming out. Only should take a few seconds. If it still overheats, you blew a head gasket and exhaust is over pressurising the coolant system.

hate to say it but you need a new Water pump. you can try to bleed out the air and it very simple remove the radiator cap put the heat up on high and let the car idle but from what your say in you need a water pump the exact same stuff happened to me and i mean everything about 6 months ago so i replaced everything with the cooling system and i mean everything starting with the small stuff working my way down the line to find the problem so i ended up have to replace the water pump. HONDA has big issues with water pumps see your loosing the anti freeze through a hole on the back of the water pump anywhere a seal is no longer present if you can do it yourself it'll take about 5 to 6 hours and cost about 300$ if you need to take it to a shop your looking at any ware for 800$ to 1000$ bucks

have you checked your radiator fans? you have two electric fans on the back of the radiator; one is the primary radiator fan and the other is the air conditioning condensor fan. if the radiator fan isn't working the car will overheat at stops and at low speeds. you should see and hear the primary fan running when your car is at a stop and the engine temp is above Normal. if its not running, turn on the A/C. if you turn on the A/C the condensor fan should come on. if the A?C fan comes on then the engine temp should drop. if neither fan works then you have two bad fan motors.

in almost 90% of the cases the problem with overheating on Hondas is a bad radiator fan motor. there is a temperature switch that turns the fan motor on that could also be bad as well as a fan relay but the chances are that the fan motor is burnt out, particularly if you've done everything with the fluid side of the equasion.

hope that helps

well i had the exact same problem on my honda. its the head gasket, trust me, i spent loads of money on mine before replacing the gasket, they didnt work. then when i replaced the gasket the head also had to be realligned, cuz of repeated overheating, so have it replaced asap. it now works fine. i HAD ALL THOSE THINGS REPLACED WHICH U HAVE BEFORE THE GASKET AND NONE WORKED. and its not the pump. if it was the pump, you reservoir wont be full, it shud be empty
