Im not really 100% sure what u mean when u say you need to bleed it before it overheats.... but heres what I know...



if you are low on coolant, the nature of our upper rad hose (being slanted downward to the engine) it will be full of air. so when u install the new rad, pour some coolant directly into that hose before connecting it to the rad (it wont spill out as long as your careful trust me), this will keep you from becoming airbound which causes your car to overheat almost immediately.



as far as "bleeding" goes, there is no such thing. You can drain or you can fill. if you get air in the system it works itself out (squeezing the pipes does help here, or you can simply run it with the cap loosened [not off]) the "bleeder" we r talking about here could just be the little wing-valve at the bottom of the rad, just under the lower hose.



ur more than welcome to pm if u have an issue, i actually just did this not even a month ago
