Well I think my head gasket is on its way out. My car was overheating for awhile until I change the radiator,t-stat, all sensors (except engine coolant temp) and all hoses (except one back heater hose)

Now the car doesn't overheat after I top it off with coolant but after a week or two I notice a would lose a decent amount of coolant. I don't see no leaks and the car only smokes white when u start it in the cold mornings. what else should I do now?

Trouble Shoot.

Check the colors of all your fluids.
Degrease your whole motor.
Check all fluid everyday.
Look for new leaks.

sounds like youre actually burning the coolant off. Ive seen it happen a few times.

To check for the headgasket theres a few things you can do. Check the color and smell of your exhaust, if its white, its possibly coolant. Also look at your spark plugs, burning coolant can cause plugs to turn white. Check the colors of your oil and coolant. You can also test using a leakdown test, bubbles in the radiator neck indicate either a cracked head, blown headgasket or cracked block. Another thing thats another easy way to check is pressure testing the system.

Well the oil and coolant isn't contaminated. However I noticed that there was some white smoke out the exhaust after the car warmed up but it doesn't smell like coolant or anything really. I remember my friends civic when his head gasket was shot it made clouds of white smoke. I know the water pump is ok cuz I see the water swirling in the radiator but could it be leaking through the seal or gasket maybe? By the way the motor is jdm and I am assuming it has atleast 100k by now. I am gonna run afew test soon to check my motor's health.
