Coolant question
Quick Question. Is it alright to just top off the coolant in the reservoir, or will I disrupt the pressure and cause it to leak???

Thanks guys, that's what I thought, but I wanted to ask the experts. The stupid manual that came with my car was meant for the 525 and M5 models, and I remebered something about pressurizing it with an airhose after adding coolant or something. All there is is a stupid 4 page "auxilary booklet" that says some things about the 530 model.
