ChadNEND Posted March 19, 2013 Share Posted March 19, 2013 I recentely bought an 04 Mack with a 427 engine. I cant seem to find a block heater on it. Where are they installed in the block, and how hard is it to put one on this engine? Thanks Quote Link to comment Share on other sites More sharing options...
DCR Posted March 20, 2013 Share Posted March 20, 2013 Not sure if this any help, but on my 2000 460 the block connection is located on the back side of the block below the valve cover. Mine was disconnected and it took a skinny guy, not me, to get between the frame and engine on the passenger side to reconnect.

felicello122 Posted March 22, 2013 Share Posted March 22, 2013 I had one on 2000 rd up front near the waterpump. They are fairly easy to install,get the kit from mack if yours doesn t have one. Quote Link to comment Share on other sites More sharing options...
