Not the case at all. Do a search and you'll see that the back sides of the radiators get clogged with road debris. If they are plugged up then it wouldn't matter if you ran with no thermostat at all.
I just replaced my oil cooler and it is the larger style like in the picture in this thread. I would suggest that you NEVER buy a used oil cooler. Most of the time a used oil cooler came from a failed engine. One look up inside and you'll see lots of places for metal debris to hide, waiting to score up the inside of your engine - the very reason i chose to replace mine.

Did the bigger oil cooler make any difference temperature wise?
