Follow th inlet of the radiator back to the water neck and on the top of it is a small 10mm bolt just back it almost all the way out and coolant will begin to seep out keep the radiator full and let it go for a couple minutes then replace. I typically will do again the following day to make sure there is no air in there. I know the USDM SR20s is prone to all sorts of heating issues and i dont baby my car so i like to be careful.
