ENGINE BLOCK HEATER CABLE ('89-'17, 6.7L - 5.9L)

  • About This Product
  • Reviews
  • Install And Tech Information


Don't be left out in the cold! Make sure your '89-'17 Dodge Cummins Turbo Diesel engine has a block heater cable so you can warm the engine for easy starting in cold weather.

The Cummins engine has the block heater installed, but many times the dealers did not order the engine block heater cable with the '03-'16 trucks.

The heater cable plugs into the block heater which is underneath the exhaust manifold and next to the oil filter. There may be a black cover on it that will need to be removed to get access to the block heater. Easiest access to the block heater is from underneath the truck.

This is a direct replacement part for the '89-'17 trucks. Heater cable is 6 feet long.

Purchased this for the inevitable trips to visit family in Up-State NY and and New England during the winter months. Easy install (wait until oil change), utilized rare earth (Nd) magnets found in big box stores to ensure solid placement on the inner-well of the fender. 1 magnet was "jb-welded" inside the fender and the others were taped to the cord/head. The JB-Weld magnet was for a constant position, but not necessary.

I installed this block heater cable on my 2005 Dodge Ram 2500 with the 5.9L. I was able to install it quickly and easily after simply removing the air intake tube. Then I routed the cable to the front of the vehicle with black zip ties. I've had it on for about 2-3 weeks and it's worked just fine. I plug the truck into a timer that kicks on about 6 hours before I leave in the morning. Thanks Geno's Garage.

Great product. Install was a snap, works flawlessly. Only improvement would be to incorporate a cap for the plug to maintain cleanliness of the prongs.

Part fits as it should and works as it should. Buy the plug protector as so as it is hard to find local.

Purchased for my '16 Cummins dually, fit perfectly. My one suggestion, don't waste your time trying to install without removing intake duct from turbo to airbox! It takes less time to remove the duct than to realize you are not as flexible as you need to be.

It's hard to find a truck in California with the winter prep group. This block heater cable makes it easy to ensure my Cummins is already warm before I start her up in the cold mornings. I will especially love it when I move to the east coast in a few months. Easy to install and very nice to have.

Purchased and installed the engine block heater myself. Had a little difficulty determining if the cord was making full contact with the male end of the heating element, as it was hard to screw the amphenol nut on. Otherwise, great product and easy to install - took 1 hour max.

Easy to install and the perfect length to reach my left tow hook. Tucks nicely into the bumper for hiding. If you are thinking about a heater cord. This is the one.

I needed to replace my damaged cord on my 02 before winter rolls in. This product fit perfectly and was relatively easy to install. I was able to remove the old one and install this one without removing any of my intake. A necessary product for any Cummins truck! Geno's was quick with the shipping and easy to work with as usual!

Good product

Like it so far haven't had to use it yet. Install pretty easy and straight forward and routing cable is a breeze as well.

It's they cord you need
Oct 27, 2015  |  By Scotty T
Just as advertised, this is the cord you need for your Cummins block heater. My truck was equipped with the block heater but no cord for it, rather than spending $45+ at the stealership I got this one from Geno's at less than half the price shipped to my door. Super fast shipping, came in 2 days and will be keeping my truck warm this winter for all those early 4am work days. Install took all of 6 minutes with a simple adjustable wrench. Can't go wrong with this purchase!
