Hi folks, great site and glad to be here. My son bought a 2005 9-5 Arc 2.3, which means when his car developed a coolant leak, and he said he needs a new radiator, I went searching for vehicle specific forums like the rest of the family fleet. I figured I should join and hopefully add to discussions sometimes and not just take advantage of every one else's past experience....like with the CBV valve. I also tend to bump existing threads instead of creating new ones on oft repeated topics.
