That's good for the Cummins in my opinion.The block heater is recommended by Ram to use when the outside temperature is 0°F or below, I use mine to help get up to operating temperature quicker. I have a smart plug programmed to turn on a couple hours before I plan on leaving if the outside temperature is less than 40°F
Why would you need it there?By gosh, I have had to use mine, even down here in sunny Southern Arizona. Though, not all night. I only plug it in when I get up in the morning.
I use it only after "cold" nights in winter. Because diesel engines do not like to start or idle cold. Even if only 40 - 50 degrees. Its far far healthier for the engine to be able to start warm. Prevents blow by into the crank case, and extends the life of batteries and the DPF filter.Why would you need it there?
I use my block heater whenever the overnight temp is -15C or lower. If it is really cold outside I also have a heated battery blanket and a 2 amp smart charger on a second cord. I use a timer to turn them on about 3 hours before my departure time. Makes a huge difference in how fast it warms up and reducing the painful sounds of that cold startup.
i agree. I too park in a heated garage, don't use block heater but I do have a battery tender on it because I don't drive it a lot. Parked outside, anything below 32F or 0 C, truck gets plugged in. That also runs the in-car warmer which means no snow or frost to scrape and the seats are decently warm without having to remote start the truck. The electricity is WAY cheaper than the gas you burn to do the same job and easier on the truck.Have it on my 16 Laramie. Truck stays parked inside most of the time in heated garage. So don't use alot. However if parked outside in Montana winter, it's helpful for shorter warm up time. I've started mine in -50, with and without the block heater. Truck likes it alot more with than without.
Good cold weather feature
I'm in Oregon of the West side of the Cascades. I drive an '09 2500 6.7. The coldest we had this winter was about 20 deg. but, like some others I leave my block heater and a Battery maintainer on all the time. It starts immediately, and I do believe that it causes less wear on the engine.
