hi

i went to cummins yesterday and got a new block heater plug b/c the stock one was "wasted" so to speak. well i put the new one on and plugged it in last night.....went to start it in this morning and she was ICE cold! any ideas whats going on? i really could use this thing in the mornings

thanks in advance

 

probably the heater element itself is bad.

 

how would i replace that? doesn't it go into one of the freeze plugs?

 

It IS a freeze plug, basically. Unscrew the nut that holds the cord to the heater, pull the cord out, and you will see how to take it out.

Be ready with a bucket - or drain the radiator first.

 

dave, id be able to pick up a new heater/freeze plug thing from cummins? and how would i install it? i remember my friend did a freeze plug on his chevy 350 i think he used some sort of permatex and hit it with a hammer into place?

thanks again

 

Cummins.

It just bolts in, it's kind of like one of those emergency expandable freeze plugs.

 

thanks dave! ill go pick it up tomorrow

 

Check for continuity between posts.

 

just put the new blockheater and cord in 50 bucks from cummins! hopefully it works because she didnt want to start this morning at 8 degrees

 

sweet! let us know how it works out for ya.

 

worked awesome! grid heater light didnt come on, the normal barely one revolution start! thanks for all the help

 

I got mine just as the one from cummins but I paid much less than the dealer was asking, I don't remember where got it but I asked this question about a year ago and found a place where to get it for cheap. The brand is fleetguard and comes with cord and all.

 

just had my block heater rig checked and I'm glad I did; the cord AND the plug/coil were absolutely wasted, beyond redemption

fortunately the water pump and thermostat were being changed out so the radiator was already emptied.

doesn't really get that cold right here on the shore of a large body of saltwater (Long Island Sound) but I like to plug both my diesels in to tuck them in at night (use a timer that cycles on from 0500 to 0800)
