    Was the car overheating when you started changing all the components? Has it run at the proper temp since the head gasket was changed?

    Need more info on when it started along with mods. You could have a block in your coolant passages somewhere or it could be a FMIC blocking all the air. Perhaps your fans aren't turning on.

    Are you noticing any coolant level change after driving and it starts to over heat? Is your reserve still full and clean? Coolant in your system, is it still a normal color?

    To go along with the coolant level/color notes...any sign of coolant in the oil?

    What made you determine the need for a head gasket change, that seems a major project for a car that's overheating?

    yea i did that

    i changed thermostat 2 months ago

    all the coolant gets shoot back out to the reserve and it boils...normal color coolant

    because the car is over heating thats why i did a head gasket change...my cousin told me that head gasket was no good because we can hear something boiling from inside my engine...

    I've never heard of a head gasket being diagnosed quite like that. Normally you'd look for evidence of coolant in the oil or exhaust. Another simple trick is to take the radiator cap off the car when cold and start it up. Watching the cooling flow within the radiator can give you an idea of well, if you get excessive bubbling/foaming, you have head related issues.

    Did you change the stat/head gasket at the same time? If the problem became worse immediately after you made the changes, perhaps you made it worse with the changes. I've seen stats that were 'new' and bad, or accidentally installed backwards.

    is that overheating a lot or just a tiny bit over the normal level. Change your rad cap. Stock ones are at 0.9, get a 1.1bar or 1.3. Did you burp it after the coolant flush?

    I had the same issue, i had a cracked overflow tank and the car would leak a little coolant at a time while driving on the highway, so bit by bit it would get hotter while driving on the highway. Check if your overflow tank is cracked. If you find nothing wrong then you need to do a leak down test to figure out if the head gasket was defective.
    Good Luck

    Is it overheating at idle or while driving? If at idle, flush the radiator, and get a new radiator cap. Also try burping the system. Basically, leave the rad cap off. Start the car, let it warm up to operating temps. You will see bubbles coming out of the coolant at the rad cap if there is air in there.
