It seems to me that if the 4 row is the same dimensions physically but with 4 rows instead of 2, it would run hotter. The reason is that they are trying to squeeze twice as many cooling lines in the same radiator. You would lose cooling space. I would think a clean system, efficient water pump and elect fan with a shroud would do more than just a four row radiator. 229 bucks is a good price, but a local shop will make up a new radiator around here for about 175....Russ __________________________________________________ Do You Yahoo!?
