can it overheat if it idles little bit high?? or if it has air in the system ??? also if it's drowing it back to the resivor??? please help it's a jspec s5 TII

If it's throwing any coolant/water into the reservoir you're either overheating or your radiator cap is defective.

Any air in the system is bad, use the bleeder screw on the radiator neck where the main hose connects to it to bleed the system of air. The manual will explain this better.

The car should be able to idle at 8 grand all day and never overheat since there's no load.

so it doesn't matter if it idles high it won't overheat?? am thinking i got a bad radiator cap i can hear air coming out out it sometimes

A high idle won't cause the engine to overheat unless there's a problem with the cooling system. The cooling system is designed to keep the engine alive when it's generating 200+hp. How much power do you think it's making at idle?

is it possible its your coolant seals? that would cause air in the system and coolant in your overflow

do you get the dreaded clouds of white smoke?

You need to test your coolant for hydrocarbons. Napa sells a block integrity test kit

It sounds like you have a minor coolant seal problem. I believe theres a method to test it in the FAQ sticky at the top of the main 2nd gen page.
Edit: looks like its not there for some reason. Basically, when the engine is cold, you take off the fill cap and start the car. If you see lots of bubbles, you have a bad coolant seal.

First make sure you just don't have a ton of air in the system, make sure you thoroughly bleed the system. The coolant seal test that sideways7 is talking about doesn't always work, so don't get too excited if you don't have bubbles, because you still may have a seal issue. I'd follow turbine's lead and get your system tested for hydrocarbons, thats a sure fire way to knwo. I don't recommend using the JB weld as a band aid, It'll gunk **** up and make it a bitch to clean everything when you want to rebuild. The worst that could happen is you would have to rebuild the motor, and once you have all the parts together thats a 3 hour job.

okay i don't see any white smoke at start up unless if i don't turn the car on for a couple of days,also i have not seen really any bubbles , but i do know that i had to bleed the system but don't know if i did it right but am pretty sure that i did it right , like i'll fill it up and the the add coolant will pop up and when i turn off the car i can hear the coolant going to the reservoir any suggestion???? please

Sounds like a seal to me, the best way to find out is to get the car tested. I had the same issues, my car would smoke horribly if i let it sit for more than like 8 hours. The car would emitt a grotesque smelling smoke screen that no one could see through. I know it sucks to hear it but your coolant seals may have failed you but the only way to find out is to get the system tested for hydrocabons, and pressurized.

where can i take the car to be tested for ?????
