2002 Honda Civic is overheating. Anti-freeze goes in to the overflow tank but doesn't return into the radiator. The tank keeps filling up until it overflows. Already changed the thermostat, radiator cap, and there are no leaks in the system.

Raise the car front end as high as possible with a floor jack, fill the coolant tank to the top, run the engine until it reaches just short of overheating, shut it down and run water over the radiator, this will burp the air out. Repeat as needed. Don't let the coolant recovery tank run dry during procedure.

should be able to fill it in two places 1 is the radiator or the overflow tank but put anti freeze in it underless you are going to fix it right away

The anti freeze is poured into the radiator water and it is necessary as the water should not freeze when in cold weather which can cause serious damage to the parts sepccially the water pump, radiator, engine water jackets/ ports..

IT DEPENDS SOME OLDERS CARS USE GREEN ANTIFREEZE.MOST NEWER VECHICLE USE DEXCOOL ORANGE ANTIFREEZE.YOU NEED TO LOOK UP TO SEE WHAT TYPE ANTIFREEZE VECHICLE USE BEFORE PUTTING ANY IN SYSTEM.IF YOUR CAP SAY COOLANT THEN THATS WHERE YOUR ANTIFREEZE GOES.

Did you make sure you filled the radiator up and got the overflow tank up to the correct level? Sometimes when you flush and drain the system and fill it back up air pockets can get trapped in the system. Start the jeep up with the radiator cap off and wait for the coolant to start flowing and when the air pockets make their way through they will escape and you can add more antifreeze.

Also, did you make sure you installed the thermostat so it is facing the right direction?

Good Luck

anti freeze goes in tthe over flow tank if there is no fluid in there check you radiator if it is full replace the cap it allows the fluid to transfer from the over flow to the radiator

I want you to take a couple of spark plugs out and examine them. If you find Anti-freeze on them then you may have a blown headgasket. A very common problem of driving a car until it overheats. I really do hope im wrong. Since it is an overhead valve engine with the cam shaft above...its a 1000.00 to 1500.00 dollar job to have it properly repaired. From here out im just going to explain why this happens...
When a car overheats - be it a faulty thermostat...low coolant...or a faulty water pump or improper coolant mixture ratio. The engine gets so hot that it actually makes the top of the engine change shape... it actually changes enough to damage the head gasket. The head gasket keeps the explosion inside the combustion chamber. Keeps the water in its coolant jacket. and keeps the oil inside its ports. When the Headgasket fails. Sometimes coolant gets into the oil (makes a milky residue form on the inside of the oil filler cap...or makes the engine oil look like chocolate milk.) or oil gets into the coolant (makes your coolant have an oil slick on top) It can also cause water to get into the combustion chamber and when the engine is running - blast the combustion back into the coolant (causes the coolant overflow to overflow or spray) or oil gets into the combustion chamber causing the plugs to get fouled (dirty). worse case...all the above happens. I hope this helps in figuring this problem out...i really do hope im wrong about a blown headgasket . As even i tremble in fear of it happening to my car. Good Luck!

i would change the tremostat and see what it does

head gasket problem you need to get it to a good garage before you ruin the motor

i had the same problem until i changed my water pump,so you might want to get that checked out
