Anyone know whether a 2F and 3F-E have the same frost plug holes. The factory part# for the block heater is the same for both but the instructions just list the 3F-E. I am assuming the blocks are basically the same. It's meant to go in the 2nd hole but that means taking the headers off. What if I just put it in the first hole instead. Will it just not heat it as well?
