Thought I'd share this with the group in case some of you are thinking of doing something to the Oil Cooler due to the cooler temps and the colder ones still to come:
I just completed blanking off part of my oil cooler today. Now I am running a consistent 200°F even in Stop/Go Traffic conditions. For the last few weeks with the cooler weather, I barely could get the temps up to 180°F. The plate covers the bottom 12 of the 19 rows, and is nothing more than an aluminum "No Trespassing" sign that I found at Home Depot painted flat black and cut to fit the SETRAB 19-Row Cooler and velcro'd to it. Z IT GO did the same, except his covers the top part of the cooler instead of the bottom. The Aluminum sign was perfect - easy to work with (cut it with a pair of good regular scissors) and paint (Roll Cage paint good up to 275°F from an Auto Store), but sturdy, inexpensive and lightweight.
