Crap Jack, we just threw the old cord away from when we installed the new heater in my sons truck last week end. If I had known that in time, I would have sent you the old cord. It was just fine, we just got all new stuff.

 

Actually, the whole cord install can be done from under the truck. I did mine in about 10 minutes without even jacking the truck (4X4). Check my album for some photo's of the installed cord.

 

Just got mine from the big brown truck tonight....does it matter if the brass grounding clip goes on the top or bottom?

 

No slide under the P side unsrew the cap and plug it in.
Holes for the wire clips, route it to tow hooks. Real easy

Why is it between the turbo and oil filter seems like a hot place to me.

Should I remove it in the summer??

 

I just installed a new block heater and cord on my sons truck and I put the ground on the bottom. I don't believe it makes a difference though. The element doesn't really care.

 

It does not matter. Think of it this way, depending on how far the block heater element is threaded into the block the ground could end up on the top, bottom, left, or right.

 

I would think it kinda does matter. The "clip" is on the plug not the "tightner" When you plug it into the heater itself it will either be on the top or the bottom, because of the way the two male prongs in the heater are interted into the female ends of the cord.

Perhaps the polarity of the prongs and the cord doesn't matter but I assumed they would.....

Either way I plugged it in so they would be on the bottom and it worked. Success.

 

No, polarity doesn't matter here. It's a simple circuit with one component, the heater (a resistor basically). A resistor or heater can flow electricity either direction through it. The grounding clip does not matter either, as long as it has a good clean connection to ground.

 

It's okay. I appreciate the thoughts anyways.

 

Ah hah said the blind man to his deaf wife.

Thanks, got it.

 

The block heaters are not threaded in on the ones I have worked on. They are held in a freeze plug opening by a "T" on the back of the heater and tightened in place by a little locking screw that also has an o-ring seal on it. I installed the new one with the element hanging down in the coolant system.

 

You guys got a good deal on the heater, I just paid $56.00 For mine!

 

My dealer only charged me $10.00 for the cord. Yea it sucks that it didn't come with the truck.

 

Yes, $35 is a ripoff for the cord. You can buy the exact same cord from the Cummins shop for about 1/3 of that. PN is 251919. The cord has been a $10 option since the '03 model. The third gen trucks are rated to start without plugin down to -20F.

 

Just checked with my Dodge dealer and they want $45 and change for the cord. Where is this Cummins Shop? Is it online if so what is the address?
