read your other post about the idle, as for the ovearheating, did you burb the system?

if not, it is quite simple.
let the car cool down.
open the radiator cap.
start the car.
add coolant/water until the radiator is capped off.
add radiator cap and lock up and your done.

 

Thanks, i filled it with water since i had more liquide than water, its working fine now, tahnks alot!
