{"text":"1999 Freightliner N14+.\nBlock heater wasn't working. I tried removing the electric cord and it came apart in block heater.\n\nI bought a complete unit to replace.\n\nFirst bolt I tried to remove, broke. The head twisted off in socket. I was able to replace the electric cord but now it leaks where the bolt broke.\n\nThe bolt is a 7/16 head. How long are these bolts. I think I will try to ez out the broken bolt tomorrow.\n\nAny suggestions.\nThanks","pics":"[]","canComment":true}
