Having to add antifreeze every 2 or 3 days..
 

I have a 95 civic coupe ex with at least 6,000 on the motor by now and I just now added about half a coffee cup or less of antifreeze to keep it where I open the cap that I just see green. Engine is not running hot or near it. Always change gears at or before 3000RPM.Also, no leaks under the car. Anyone know or is this normal?

Check the condition of your oil, if it looks like a milkshake then you're head gasket is bad and the AF is mixing with your oil. Can also have oil mixed in with the antifreeze so check the condition of that as well.

did you bleed the system?
when car is warm listen for any hissing and look for any wet spots

Well when I looked inside radiator I didnt see no signs of oil in it. Same with oil which looks the same as to when I had it changed....6 days ago.

Sry for DP but no didnt bleed it.After driving around in it when I turn it off I just hear I guess motor or intake winding down? I dont think its a head gasket problem because theirs no smoke from exhaust like the 240sx did when I blew gasket on it. I called brother and he said its prob still going threw the system since it just has 6,000 miles on it?

There's a lot of little hoses on the back of the engine and the manifold that can leak. Inspect them, especially looking up from under the car. Check for leakage out of the hole in the water pump near the alternator.

Leakage like air? Cause nothing is leaking under the car. I also checked all the hoses and the ones with clamp are obviously really tight.I dont really know what to do with the hoses that have no clamp and just slide on?
