Fred ... my car is ERA 757 , .... I blocked off the
oil cooler this summer and ran
oil temps in the 140 to 180 degree range when just cruising . If I get on it , they will go to the 200 degree range .... and our ambients down here in summer are in the mid 90 to upper 90 degree range . Since we haven`t seen any cooler weather yet ( still in the upper 80`s ) , I don`t know what the
oil temperature will do in cold ( for us ) weather. Our typical winters are lows in the low 30`s and highs in the mid 40`s . I made a cardboard template and then cut a piece of 1/8" Lexan out for the shield so the oil cooler could still be seen . I followed Doug`s advice and put a small piece of tape on the oil temp. gauge to remind me the cooler was blocked .
