Ah ha! I think this may be related to my other active post right now.

My car has no separate oil cooler element up front by the rad. What I think that Volvo may have done was to make the radiator wider and then add an oil cooler right at the oil filter mount. You see I'm having an interference problem while trying to fit an Amsoil filter because its extra long. There is a coolant line coming down off of the side of the block that won't let me get this long filter in there. So what they probably did (probably 92 is the first year for this) is just use engine coolant to cool around the filter base and then make the rad larger to add more cooling capacity. That's why Amsoil thinks that the filter will work is because its worked on older models and will work on the newer nonturbo models.
