Zerostart 3500022 Engine Block Immersion Heater for Cummins, Paccar, 3/4" NPT Thread | CSA Approved | 120 Volts | 750 Watts

I am thoroughly impressed with the product's quality; it meets my needs perfectly. The attention to detail and craftsmanship truly stand out, making it a worthwhile investment.

Will fit 2016 Ram 2500. I cross referenced the Cummins part number to match this. Installed without issue. Most likely would also fit through 2024 as Cummins used the same oil coolers at least up through this point.

Perfect item and works great

2003 Ram 2500 Block heater, the install was easy and it work prefect.

Replaced my stock block heater in my 2001 Dodge Ram 2500 with this. Easy to install, working great and cord is long and durable feeling. Very happy with this part.

Perfect

I installed this only a week ago and have used it twice and it works well so far. Make sure you have a pan below to catch the coolant that escapes when you remove the old one. A good idea to have the new one prepped with Teflon tape or other acceptable sealant on the threads and ready to grab quickly to limit the coolant loss. I lost about a pint during my install. Common sense tells me it may be a good idea to run the engine for a bit before plugging the heater in so it has a chance to get immersed in the coolant. I don’t know if plugging it in dry would damage it, but I’d rather not risk it.

It's newly installed, fits my 2005 dodge ranm 5.9.

easy to install , same as the stock one

Perfect fit. Get a 5/16 clear tube about 2 feet long to drain radiator fluid into three 4 liter jugs Take off airbox and tube to turbo with 8mm ratchet with a 1/2 in ratchet use a 8 inch long extention with a 1 1/8 socket and a snip bar Replace with new part and dab some liquid teflon. Make sure the have the 2 plug post diagonal because the plug has a 90 degree and you will have it facing down this way. I paid 47 bucks for this part, price is outrageous right now Cheers

I bought two of these after the block heater on my Cummins died in the middle of winter. I live in Canada and the winters here can be brutal. I don't like cold starting my diesel engine unless I have to. I installed one of these a couple of years ago. Install was straight forward. You don't need to drain coolant.. You just need to be able to switch them quickly. The new one threaded in perfectly. No leaks. Has worked perfectly through 2 Canadian winters. I also like that this is made in the US.. Good quality block heater. I now have 1 for backup.. Just in case.

Been on for a few months going strong.

Works good. Fit was perfect for my 2012 ram 2500 with 6.7 Cummins
