Thanks. Well I was just wondering about the pump noise beccause the one in my 89 560 is almost quiet just like light silent hissing. There is no accident history so I dont think that is why the Rad was replaced. The owner told me the Rad was leaking and so that is why it was replaced as I just asked them again today about it. hopefully I can get this car for $15 since I have to replace some dinged chrome moudlings and fix a leaking A/C that was fixed already. My mech told me to go for it and the problems he saw were minor fixes. I will keep you guys posted
