Fast heat?

[amauri]

My question is for you guys with some of the newest RAMs, Do your trucks make heat that fast?

Takes my third gen about 10 minutes.

Starting with 2019, Supplemental Cabin Heat option is included with Cummins diesel package.

Supplemental Heater
Packaged with the 6.7L Cummins® Diesel I6 engines, the supplemental heater keeps the back of the vehicle warm on cold days.

On my 2019 3500 HO, I have heat coming from the defroster within a couple minutes even at temps of -15F and not using the block heater. The electric aux. heat works well.

The old Suzuki Samauri that I had a few years back had ya all beat for fast heat. 10 degrees out start engine roll down 40 foot driveway and had warm heat coming out of the vents. By the street corner about 600’ later the heat was hot . When I first bought it I thought that I’d freeze my back side off in it with the canvas top. Was I ever wrong. Only down side was the heat was ether full on or full off. As cheap as those cars were they were tough as nails.
Now all my ram’s have poor heat unless you are towing. The 13 has those two radiators way too much cooling power

On follow up, my 17 heats very fast too. Heated seat and steering make it feel warmer too. When we were camping in the Northwestern US, remote start and heated seats made starting up very comfortable with outside temperatures in the 20s.

I noticed the trucks cooling fan engages, it sounds like a turbo prop. Very efficient.

I started this morning in mid 40 outside, 1.5 miles was very hot in the crew cab, no plugged in, no heated seats, no heated steering.

In the past only European fca vehicles had the electric cabin heaters. I’ll have to do some digging to see if that has changed

I had to pop back in on truck heat... I had to turn off the auto turn on feature for heated seat and steering wheel... we were in Arkansas last year with outside temps in the low 20s. Started truck, went down the road, got too warm, shut off the steering and seat heat manually, but kept immediately coming back on seat on high. My Ford and Chevy passengers were amused. Finally, pulled over, placed in park, turned off auto feature, shut truck down, restarted, and continued on. The high setting on the seats can toast your buns. Not sure what outside temp triggers it and not sure if updates may have fixed it. Sitting inside the mancave and hardly ever getting cold down here, hard to test.

Anyone else have persistent steering seat heat. Like I said, at the time in auto mode, could not turn off without turning auto feature off. You'd figure manual controls would override it at least until next startup.

Cheers, Ron

Service info confirms The 19 models are equipped with electric cabin heater. More modules and more chance of having to remove dash panel to make repairs. These trucks are getting to be very plush indeed

Ford has had a rapid heat system, electric heater. Available in the super duty for a while now. It works ok not great but some heat at start up is way better than none at all.

 

[R.Taylor]

My '19 3500 will make warm air as soon as soon as you start it.... Even when it's 32 outside. Other than that, It over all does heat up quicker than my '06 or '18 did.

Pretty certian our 2015 ram eco diesel had pre cab heating. Nothing great but helped.

 

[shorthorn]

My '14 doesnt heat up too bad, with the exhaust brake on and set at High Idle. Nothing beats my Audi Q7 TDI Daily driver though... It has an auxiliary electric heater to heat the cabin until the engine is up to temp. That would be very nice on these pickups! My 05 Cummins was the slowest warming vehicle I have ever seen... I contemplated putting a space heater in the cab on an inverter or something... it was awful!

Preheating coolant year-round always a winner. Temp must always rise to same op temp, cold weather just means a longer rise.

I think of this way:

Summer? Needs 100-F heat rise
Winter? Needs 150F heat rise.

Either way, it’s a long climb. Preheat means less fuel burn year-round as well.

Heating the lube oil without cooking it more of a task. But it can take 45 highway miles big truck or little (with early HPCR and older) to get it to op temp.

And, as to winter fronts, on my ‘04 ONLY the MOPAR piece fully covers the heat exchanger cross-member top to bottom. In the below 31F ONLY specified operating range, it’s great.

Were that not offered, I’d make one.

That electric rapid heat system has to put some draw on the electrical system... I'd imagine when you get that feature, dual alternators are standard?

As I stated on post #21 above, that feature is std equip with the 2019 Cummins diesel package. A 2nd alternator is not included.

 

[Prairie Dog]

It would be very interesting to find out what the power draw is of the Rapid heat system...

It's all about Emissions, the engines must heat up fast to comply with the latest regulations.
A lot of heat can be made internally by timing the injection events a little differently.
That simply wasn't needed in the past.

Gas or Diesel doesn't matter, all need to do it fast.
My last Class8 needed just 5-8 Miles to reach fully operating temperatures, water AND oil.

The heater is located in the heater box downstream of the heater core. It consists of three 400W resistors, which translates to 100 amps at 12 volts.

Operation is automatic, based upon the following conditions being met:
-Engine must be running at 700RPM or greater
-Outside temp is below 68F
-Coolant temp is below 158F
-Battery voltage must not fall below 12.6

It's almost as if they thought it through.

This only produces heat if called for by the control settings I hope?
