EchoIntegra

I apologize if this is posted in the wrong place.

I have a 95 integra ls. I have been slowly losing coolant and can't figure out why. I don't have any leaks, my oil doesn't have water in it, my water doesn't have oil in it, no white smoke coming out of the exhaust. The car runs great and seems to have all of it's power. I was thinking it has a blown head gasket but there is no indication of it. Any ideas?

how about when you sit in traffic/let it idle for awhile, does it over heat?

Put a pressure tester on it. Pressurize it to 15 psi or so. First, see if the reading drops. If it does, hunt for the leak. If no visible leaks are present, leave the tester on there for a good 20 minutes or so. Take the tester off and start up the car. If you see a puff of white smoke, it's leaking into the combustion chamber

pretty much this

3 really common leak points

1. the cap
2. the radiator
3. the block or head warping allowing coolant to blow by

You will usually be able to smell antifreeze if it leaks into a hot engine bay. Sometimes before you see or find it.

you can smell it in the exaust too... it will have a sweet smell to it
