Block heater woes -301

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Have a 78 545B loader with 301 engine. I've put 2 new 1500wt block heaters in it. First one 10? yrs ago which worked once or twice before burning plug end up.Post melted. Put last one in Dec 24. It set alot because of tranny issues. Fixed trans over summer and put about 75 hrs on since. Have been pluggin in for cold starts and everthing was good,until today. NOT WORKING! Stone cold. Have used heater maybe 10 times. It had a non working unit in it when I bought it. It is mounted in a thick plate (1" thd) bolted to the front of block on rt side below and toward rt of water pump. (engine in backward) There is a narrow water passage running length of block where it is. The element is about 5in long and does not touch block but is very close fit. Is it too confined and cooks itself? last was zerostart brand. The 190 and 7020 tractors have a diamond shaped plate at rr end of block (according to parts book) that uses a hooked heater with plate.  That port has a water manifold bolted there which goes around block and feeds engine and trans coolers on other side. There is a diamond plate on front left side of head. Would that tractor heater fit in the head and work? I'll have to get the plate off to see how much room is inside there. Inet shows a 400wt little short version element that would fit in my current location but is 400wt enough to warm it in a couple hours? I'd like to stay with the 1500wt heater but can't get them to live. Any help appreciated.
