Expansion tank M3
I have my radiator out on my E36 M3.
Should I expect an expansion tank with the ETD aluminum radiator and if not how critical is a new expansion tank, I like to go quality but have to watch money.
Why would you have to drain the entire system? The block coolant should be fine left alone right?
I found out that to loosen the fan on 3 cars the best tool is a thin screwdriver about 7" long as you can wedge it against the pulley housing and a nut and lock it straight above near the metal above the therm housing. Play around it is a sweet trick IMHO. I just used a cresent wrench on the 32m and it had foam on it to cushion the soft blow, real easy.
