I am wondering if anyone out there is familiar with the Cat D-318 engine...? I want to install a freeze block style heater in it. I see one place where I could possibly install it? There is a panel on the side of the block that has a threaded square plug. Can I use that port...?
Check out this thread, it's about a D4 7U that has a D315 which is same as a D318 except that it's a 4 cyl. instead of 6 cyl. http://www.acmoc.org/bb/showthread.php?4918-D4-block-heater
