A new Ram delivered in October isn’t the same vehicle the day after it arrived from the factory as the day you drive it home from Beadle’s. Between those two days, our service bay puts every truck through a cold-weather prep checklist designed for South Dakota winter — block heater hookups verified, fluids checked at our regional temperature norms, batteries tested for sub-zero starts, and 4WD systems cycled on the lot before you ever turn the key.
This guide walks through what Beadle’s actually does to every new Ram before delivery in cold-weather months — what’s standard pre-delivery work, what we add for SD conditions, and the small handful of things you can check yourself in the first week to make sure your truck is winter-ready when the temperature drops.

What Does Beadle’s Do to Every New Ram Before Delivery in Winter?
Every new Ram that comes off the truck onto our lot goes through pre-delivery inspection (PDI) before a customer takes it home. In cold-weather months — typically late October through early April in our part of South Dakota — that PDI includes a regional cold-weather layer on top of the standard Stellantis-required checks.
The cold-weather work is the result of decades of selling Rams in a state where -20°F overnight isn’t unusual and a stuck block heater plug or a weak battery can ruin a calving morning. Most of it is invisible to the customer — the truck just starts when you turn the key — but it’s the difference between “it ran fine in the showroom” and “it runs fine at 5:00 a.m. with a 25 mph north wind.”
How Does Beadle’s Verify the Block Heater System?
Most new Rams sold in our region come with a block heater factory-installed (and on diesel HDs it’s standard equipment). We verify three things before delivery: the cord is in the engine bay where it’s supposed to be (not stuck behind a dust cap), the cord routes cleanly to a usable plug-in spot, and the heater itself draws current when plugged in.
If the cord is missing or the heater doesn’t draw, we fix it before you take delivery. We’ve seen factory cords get tucked away during transit and the customer not find them for two months — by which point a -10°F cold start has already happened.
For Cummins diesel HDs especially, we walk the cord to a customer-accessible spot and tag it with a small flag so it’s not buried under the front grille on day one.
Best for / Less critical for
Best for: SD, ND, MT, and northern MN buyers where overnight lows below 0°F happen most winters. Less critical for: buyers in milder microclimates or southern states — the heater still helps, but the cold-start risk is lower so the verification matters less.
What Cold-Weather Fluid and Battery Checks Are Done?
Coolant mix is verified to the cold-rated ratio for our climate, washer fluid is replaced with the cold-temperature blend (the factory often ships with mild-climate washer fluid), and on diesel trucks the DEF system is verified along with the fuel filter status.
The battery gets a load test, not just a voltage read. A new battery from the factory can show 12.6V on a multimeter and still fail at -15°F if the cold-cranking amps are under spec. If the battery doesn’t load-test clean, we replace it before delivery — every time, regardless of the calendar.
Engine oil is checked at the level marked by Stellantis for our region’s operating temperatures. For diesels we verify the fuel filter is clean and that the truck has cold-weather diesel (not summer blend) in the tank if the dealer next to the factory shipped it on summer fuel.
Does Beadle’s Test the 4WD System Before Delivery?
Yes — every 4WD/4×4 Ram on our lot gets the transfer case cycled through 2H, 4H, 4L, and Auto modes (where applicable) on the lot before delivery. We listen for the engagement, watch for the dash indicator, and confirm the front axle locks and unlocks as it should. A factory-fresh 4WD system can be electrically right but mechanically stuck if a truck has been sitting since assembly without being cycled.
For Power Wagon and Rebel buyers, we cycle the locking differentials and the disconnecting front sway bar through their full operating range too. If anything feels off, the truck doesn’t go to delivery — we get the repair done first.
How Does Beadle’s Set Tire Pressure for South Dakota Winter?
Tire pressure changes by about 1 PSI for every 10°F change in temperature. A truck shipped from a 70°F factory and delivered into a 10°F cold snap can show a TPMS warning the first morning out — even though nothing is actually wrong with the tire.
We set tire pressure to the manufacturer-recommended level for the loaded condition you’ll be driving (which we ask about during the pickup walk-around). For most customers that’s the door-jamb spec, adjusted for the ambient temperature on delivery day.
A Practical Note on Winter TPMS
If your TPMS light comes on the first cold morning after pickup, it’s almost always temperature-related, not a leak. Check pressure at the door-jamb spec on a cold tire (before driving) and add air if needed. If the warning persists after re-inflation, bring it back to us.
What Cold-Weather Features Get Walked Through at Pickup?
If your truck has remote start, heated seats, heated steering wheel, heated mirrors, defrost cycles, or auxiliary cab heat (on the diesels), we walk through how to use each one before you leave the lot. UConnect’s settings menu has options buried two and three menus deep — figuring them out at -15°F in your driveway isn’t fun.
For Power Wagon and Rebel, we walk through the off-road cold-weather differences too: where the heated grip warmers are routed, how the locking diff behaves below freezing, and what the driver-selectable terrain modes do to throttle and traction settings in icy conditions.
What most cold-weather buyers overlook
The cold-weather feature most often missed at pickup is the remote-start runtime setting. The factory default is usually 10 minutes — fine for southern-state weather, sometimes too short for SD mornings when you want the cabin warm and the windshield clear. We can set it to the longer runtime in UConnect during your pickup walk-around if you ask.
Quick Reference: What’s Done for You vs. What to Check
| Item | Beadle’s Handles It | You Should Check |
|---|---|---|
| Block heater function | Yes — verified before delivery | Plug it in the night of your first hard freeze |
| Battery cold-cranking | Load tested at PDI | Note any slow-crank symptoms early |
| Coolant mix | Verified for cold-rated ratio | No action needed |
| Washer fluid blend | Replaced with cold-temp blend | Top off as needed |
| 4WD engagement | Cycled on the lot | Engage briefly during your first cold week |
| Tire pressure | Set at delivery for current temp | Re-check on the first hard cold snap |
| Remote-start runtime | Set to your preference at pickup | Adjust through UConnect anytime |
Best for: any new Ram buyer in the SD/ND/MT region taking delivery between October and April.
Not strictly needed for: trucks delivered between May and September, when most cold-weather work isn’t seasonally relevant — though we still verify the systems for the next winter.
How to Verify Your New Ram Is Winter-Ready in the First Week
Most of the cold-weather prep happens at our shop, but six quick checks in your first week confirm everything is dialed in for your specific use case and home temperatures.
- Locate the block heater cord: It should be tagged or visible in the engine bay. If you can’t find it, call us at 605-460-6254.
- Plug in before the first hard freeze: A 4-hour pre-warm before a cold start is enough on most modern Rams; longer doesn’t hurt.
- Verify remote start works: Test from inside before the first sub-zero morning. Confirm runtime is set to your preference.
- Cycle 4WD or Auto mode briefly: Engage and disengage on a clear road to confirm the system is awake.
- Check tire pressure on a cold tire: First thing in the morning, before driving. Compare to the door-jamb spec.
- Test heated seats and steering wheel: Run them up to high once to confirm operation. Verify defrost works on the windshield and rear glass.
Key Takeaways
- Beadle’s pre-delivery inspection includes a regional cold-weather layer on top of standard Stellantis-required checks for trucks delivered between October and April.
- Block heater function, cold-rated coolant, cold-temp washer fluid, and battery load test are all verified before customer pickup — not assumed.
- 4WD/4×4 systems are cycled on our lot before delivery; locking diffs and disconnecting sway bars on Power Wagon and Rebel get the same treatment.
- Tire pressure is set at delivery for the current temperature; expect a TPMS warning on your first hard cold snap that’s almost always temperature, not a leak.
Frequently Asked Questions
Does my new Ram come with a block heater?
Most new Rams sold in the Northern Plains region come with a block heater factory-installed; on Cummins diesel HDs it’s standard equipment. We verify the cord is present and the heater draws current at our pre-delivery inspection. Confirm with your salesperson during the order or build conversation if you want it called out specifically.
How long should I plug in the block heater before a cold start?
A 4-hour pre-warm is enough for most modern Rams in temperatures down to about -20°F. Below that, longer is better — overnight on a thermostatic timer is a clean solution if you have one available. Plugging in indefinitely doesn’t damage the truck.
Why does my TPMS light come on after the first cold morning?
Tire pressure drops about 1 PSI for every 10°F temperature drop. A truck delivered at 30°F and parked overnight at -10°F can drop 4 PSI through no fault of the tire. Check pressure on a cold tire (before driving) and re-inflate to the door-jamb spec. The light usually clears after a short drive.
Does Beadle’s swap the washer fluid for cold weather?
Yes. Factory washer fluid is often a mild-climate blend that can freeze in our temperatures. We replace it with cold-temp blend during PDI for trucks delivered in the cold-weather window. Top-offs are on you for the rest of winter.
Can I adjust remote-start runtime myself?
Yes — UConnect’s settings menu has remote-start runtime adjustment buried a couple of menus deep. We can set it for you during the pickup walk-around if you tell us your preference. Default is usually 10 minutes; longer is available for cold mornings.
If my truck doesn’t start in the cold, what should I do first?
If your truck is under warranty and won’t crank or starts roughly in cold weather, call our service department at 605-460-6277. Don’t repeatedly attempt cold starts that drain the battery. We’d rather diagnose and fix it under warranty than have you fight it through a winter morning.
My Take on Cold-Weather Prep at Beadle’s
In a state where -20°F mornings happen every winter and a no-start day can mean missed cattle work or a kid stuck at school, the cold-weather prep on a new truck isn’t a sales feature — it’s just doing the job right. Our service team has been refining this checklist for decades because the customers who buy trucks here actually use them, often hard, in conditions the factory PDI checklist doesn’t fully account for.
Most of what we do happens before a customer ever sees the truck — block heater verification, battery load test, coolant ratio check, washer fluid swap, 4WD cycle. The customer-visible piece is the pickup walk-through, where we slow down and make sure you actually know how to use the cold-weather features your truck has. Take that 15 minutes seriously. It’s the difference between figuring out remote start in your driveway at 5:00 a.m. and having it ready to go.
