OK I have a 1954 with the 235 engine and am having issues with cooling while at long idle periods. I have done all the suggestions but nothing solves this issue. I can put a shop fan in front of truck and idle it a day so its and airflow issue with the fan I guess. I have read that the Flex A Lite 118 works on these trucks with a controller installed in the cooling fins. I just want to be sure before I pull the trigger and get this fan. ANY suggestions will be welcome thanks
