Coolant/Radiator Problem?!

[angilfyre]

Hi..
I have a 1994 325i 4door sedan. The problem that I have is the radiator has a hole in it, by the drain plug. So I am replacing the radiator, all of the hoses (upper, lower, overflow), the expansion tank and cap, belt on water pump, sensor attached to expansion tank and replacing the antifreeze with BMW coolant. Would it be better to take it to the dealership to get repaired? Because I see that getting all of the air out of the system might be a problem, making my cooling problem return.

I had a very similar problem with mine a few months ago.
I bought the radiator and did it myself.
It is not hard to get all the air out just time consuming.
There is a small screw next to the radiator fill cap. It is basically a bleeder screw. Fill the radiator with water/anti-freeze, put cap back on and let the engine warm up to normal level. Turn the car off and open the bleeder screw untill steam start coming out. Fill radiator up again and repeat the process until when you open the bleeder liquid comes out.
