Well ive finally decided to replace that radiator. the swinging point was a friend of mine parting out his family S70. (litle brother..um,,totaled it.) which is bad if you are them but good if your me. which i am. So I have the rediator and am prepared to take it and the car into my "trusty" local mechanic and he assured me that it wouldnt take any longer then four hours to replace my faulty radiator with the good new one. being a natural born cheapskate Im thinking four hours is a pretty highball estimate and mechanic is attempting to recoup his loss of profit from my providing the part. am I right? should I tell him that I will not accept anything over two hours? I could have a reasonably humorus situation on my hands here, but a potentialy hazardous one for my beloved 850.
