If it is, than turbo pressure can over pressurize the system and not allow for coolant to re-enter the system. As for me, I dont have the throttle body heated anymore.
Can't say you don't learn something new everyday................sure would like to know how this happens at the TB !!!! ?

LOL. I knew there was a reason to pull the thermal wax unit off that TB.........damn that thingy.

how fast does it overflow cause b4 my engine popped it would run for about 45 min of light throttle driving b4 anything then if you got on it it would start overheating. did this for prolly 3-4K then one day after bringing it home hot when I started it next it ran shakey and puffed thick white smoke. coolant seal had a crack in it

I am not a heater expert but my lame understanding is that the "heater" get's it's heat from the engine. So when you turn on the heater you are essentially dissipating that heat quicker.

YOUR COOLANT SEALS ARE SHOT !!!!!! , I experienced the same thing a little while ago after overheating badly and not knowing it . the symtoms I saw were the same , normal temps , even at idle , then suddenly it would shoot up to 220 + , constant overflowing of the coolant bottle and lots of bubbles coming out the fill neck.
My checks were ...............
1. filled it and started it up , stick my finger in the filler hole for a little while , while the water is still cold of course ! after removing my finger the water shot about 20 feet into the air , this suggests that the system is under a lot of pressure way before it heats up.
2 . Filled it up again , started it up and let it puke ! I then took a lighter and lit it at the open filler neck ! guess what there was a nice blue flame burning on the filler neck like a low pressure tourch ! , this suggests that some king of combustable gas is present (gasoline?)
3. last one I did was to fill it back up , start it up , let it puke and heat up (overheat) then shut it down and allow it to sit overnight . I then pulled the plugs the next day and guess what ? WATER ! and lots of it , if you turn it by hand you'll be shocked to see just how much was in there !
Don't deny it , the sooner you deal with it the sooner you can get back to enjoying your car !

Wow thats alot of good info. my denial on my coolant problem started on saturday and from what the title says i didnt think i would find my possible answer here. This problems been bugging me since saturday when i started up my car in the mornin. Hearing that buzzer going off for the first time ever is a nerve wrecker.
time for more troubleshooting

The first one is very good, because normally the only time there is expansion in the coolant system, it's when the temperature of the coolant rises. (Direct relationship between temp. of your coolant, and the volume/expansion of coolant.) If the coolant is expanding before it's heated up, you know the expansion is due to another variable, and the only likely variable is the combustion that would be over-pressurizing the coolant system.
The 2nd test is just flat out ballsy, but shows the same facts.
![Icon16](https://www.rx7club.com/images/smilies/icon16.gif)
3rd test is also viable and has been discussed before.
Do a pressure test first, and then try some of these if you need more evidence to justify tearing into the engine. Between the pressure test, and the three listed here, you should know with 95% certainty if your o-ring is compromised.
![dunce](https://www.rx7club.com/images/smilies/dunce.gif)
I agree though, sounds like the o-ring seal is compromised. Good luck!
