Hmmm.I believe on yours, the tranny cooling lines are external from the rad. So I don't think it would be a problem, as long as you don't go with the cheapest built thing on the market. If you get one that is thicker than the original, you may end up with clearance issues between the fans and the exhaust. Other than that, there may not be much else to worry about. But I have never installed an aftermarket rad on a cadillac before, so I don't know what all to watch out for.
