I have an engine block heater plus I have an oil pan heater I put on the fuel filters so the fuel can circulate so it dosent blow the fuse on my lift pump till the lift pump heater can get things warm enough to keep the pump housing warm

They I got a question about my lb7 duramax cold starting could we get in contact

Tttttttttt​@@perryhanson7878

lmao

Ran over a speed bump and my fell off as well 🤷‍♂️

Mine had one on from the dealer, but then fell off in my driveway. They just don’t make things like they used 2 😪

What model dmax is his red truck sounds crazy

What also is happening is the alternator is being commanded to not charge during initial startup to not load the engine down when cold

They also make replacement oil seals....

Our city has a 3-minute max idle time with fines of up to $600.00. Ya go figure that out backed by the Health officer. Clean air initiative.

I'm also in Alberta. That -45 and colder weather we had sure did a number on my '04 Yukon lol

@@KyleJewellyeah.. the ol lml didn’t shut off for pretty much four days lol. That wasn’t fun

@@dmaxman321 lol i hear ya. Just a little bit of cylinder washing going on

@@KyleJewellthat’s what they tell me

Yeah that guys just trying to sell

This stuffs a gimmick. If cold starting was this big of a problem, these engines would not last 300,000-700,000 miles & more before rebuilds. Start the truck, let the oil circulate for a few minutes and drive it.

@PndaS2k I don't want to totally discredit the idea, I'm sure there is merit to the topic but I don't think it's as major of an issue as it seems to be in the video

Good salesmen can sell ice to Eskimos

I hear what you're saying. My solution is plug them in, or better yet have a Webasto type heater on the engine and run full synthetic engine oil.

I agree. I’ve had tractors from the early 60s with a circulation heater for the coolant. They used to cost about $30 and were incredibly easy to install. They would start just like it was 80 degrees out.

😊

Thanks for sharing WOW! Sounds like a blast literally 😂 when I was in the Army we blocked the exhaust for back pressure and used ether

Don’t most come with a block heater? Mine did and my cummins also did

Is that a factory setting or aftermarket add on?

@@Oliver0200 elevated idle is a factory setting that can be enabled or disabled on the dash menu. High idle is also an option from factory and can be programmed in the by the dealer where you can set the park brake and set your cruise in park and it will idle up to 1200rpm for PTOs and things. This doesn’t build heat as well as elevated idle, but does keep your oil pressure up if you had to idle all day. Some aftermarket tuning offers high idle options etc depending on the application

Great info

If you live in the northernmost part of the country you should be plugged in in the coldest part of the winter Or at least running 5w40 or 10w30 full synthetic oil. Cold start it , ramp it up to 1200 rpm after 30 seconds and let it run 3 minutes or so , drive off gently.

​@@JohnDiMartino0w40 T6 year round and is great in winter.

I'm running 15w40 is that bad

5f to 20f

Proof?

Not true, may say that online but my lml’s block heater works even at -5 C

In the book on 2015 gmc,it says block kicks in at -15 degrees

Central Wisconsin, so it doesn't get super cold all winter, but for 3 months it's definitely below 30 degrees and plenty of days -10 degrees.

@@michaelzeinert2074do you plug in ur l5p ?

He can't afford to plug it in

How does it do this if the truck is in park?

About how many minutes should you idle it for? 2022 L5P with high idle.

It commands the TCM to stall/lock in the converter

Also individual glow plugs continue to run on/off for a bit even after the engine has started...the ECM and glow plug control module are smart enough to see how “hot” each cylinder is during a cold start, if it sees one cylinder is colder during cold start and isn’t firing completely due to the cold, the ECM will command the glow plug just for that cylinder to stay on longer to help that cylinder heat up and run better on its own. It's pretty smart and some tuners ruin this feature.

@@agger838 That’s pretty cool. I never knew it did that

True that lmao radiant floor heating FTMFW! I spent far too many years rolling in mud puddles, or slush. Not to mention my vehicles rust to crap because for 7 months a year it's covered in salt and frozen road grime. Now just let it melt and squeegie it down the drain.

Depends on year and what not ... I refuse ... hear me out why... active grill shutters manages all the cooling and warming

I noticed the same thing, I’m not willing to risk that high of oil pressure and cause a engine failure

@@jordanoleson8343 I'm always worried blowing the seal on the oil filter.

I have a mechanical gauge on my 12 valve Cummins that tops out at 75psi. On cold starts that needle SLAPS the little peg at the far end of the gauge. God knows what the actual pressure is. It doesn't come off that peg for a good while too. I baby it until the temps reach about 160. The box truck I took it out of had 501,000 miles on it, still had the cross hatch on the cylinder walls. And I imagine this engine has seen thousands of cold starts. Still chugging along happy as can be.

^^^ THIS. Oil pressure is why I let my 2015 LML warm up for a few minutes. I live just off a State Highway with 65 MPH speed limit. No way I am jumping out on that and mashing the throttle. Cold start idle pressure is at 90 PSI. If I get in and drive, it quickly pegs the gauge at 120. Anybody ever try pouring oil out of the jug when it is at zero degrees? Imagine forcing that thick honey through main & rod bearings with 0.003 inch clearances. So you might be saving your cylinders, and wearing out your bearings by driving off in frigid weather.

​@@Bloodbain88I've seena 100psi guage peg out on a 02 Cummins on idle in the cold. That same truck pushes 30 psi on idle hot. Personally I'll let it run for 15 mins

Pump rub fix if it’s 4x4

Ya but all these items besides the ventech require input/actions from the owner/operator, someone needs to plug it in, put the cover on etc.. as your aware people are getting lazier and dumber where the ventech has its own brain so they make sense in alot of applications

@@JackWorkz True, LOL But the video is about cold starts which the Ventech does nothing to help with cold starts all it does is make the heater warm up faster. LOL

@@rangervapes571 fair enough 😃, definitely not something I would spend money on

Isn’t the thermostat supposed to do this?

thedieseldudes.com/search?q=lhg

Which oil? I'm running 15w40

Should be thick enough to leave good film but also thickens in the cold

It will work if it’s deleted

WD40 the cylinder with the injectors turned off with a hot motor.

Whatever you do don't break it off. Or you'll be looking at 30hrs of labor to pull the head to remove it possibly. Try getting the engine hot before trying again

​@@agger838 You don't have to remove the head. There are kits out there to remove broken glow plugs

@@agger838 I don't have a code on that glow plug so I could just leave it but since I changed all the others I wanted to keep it uniform. Based on the videos I have see with the air hammer tool I order, mechanics said it will save the headache and break free all the carbon causing it to be stuck. I have been moving slow with the ones that were hard. Kind of like when I changed the exhaust manifolds. The bolts took me a long time to get out but I was able to do it without out breaking any. I think if I had to pay for a broken one I would just get a new engine at that point.

@dustinryan9671 if u or a the mechanic breaks the glow plug they will try to weld a nut on if thy doesn't work they'll usually want to pull the head. I opted to roll the dice and drill mine out. I ruined the threads being off center. I then had to buy a time sert kit and that worked and saved my butt from probably buying a new head

20+ Duramax has dampers on the front that open close as needed to keep the engine at temp in cold weather: "There’s also an “ice mode” that activates when ambient temperatures fall below freezing. By working in conjunction with onboard sensors and a thermometer that monitors outside air temperature, ice mode prevents movement of the aero shutters until ambient temperatures rise above the freezing mark or until powertrain temperature has reached a healthy operating temperature" Pretty neat really, I had my truck for almost a year before I found out about this feature , I was just washing it and went to rinse the dirt from the radiator and I couldn't even see it, all the dampers were closed

Ya its a cool concept but my philosophy is keep it simple! What happens when them shutters get stuck in the closed position?! To many things to go wrong and fail. To many sensors and moving little plastic parts to break. All that moving shutters and stiff behind the grill makes it that much more expensive after a crash. Lol All these new trucks have just gotten nothing but cluttered and over loaded with gadgets and bells and whistles. I don’t need a shutter thats electronically controlled by a thermostat and the PCM to determine how much air flow to let in the front of the truck *eyeroll* . I get the theory and philosophy behind it to help warm it up faster blah blah blah. If i want to maintain a higher temp in -30 degree weather like here in gunnison colorado like it will typically get in jan, feb, ill out a pizza box inbetween the radiator and the intercooler, that way the intercooler still gets fresh cool air and the radiator is being blocked off, wither completely or partially depending on what I’m doing l. But hell i barely even drive my second gen HO 24v in the cold or the snow. Its a garage princess in its heated garage during the winter months. Just to many things to go wrong on these new trucks. They’ve gotten way to complicated that in 5-10 years when they are broken down and all the little plastic pieces have broken and sensors have stoped working, their isn’t going to be anyone that knows how to work on them, or wants to anyways. To many sensors, modules, to many cheaply made plastic parts and moving parts. 20 years from bow it’ll be interesting to see whats broken down on the side of the road because of a $15 emissions related sensor. Or a lot full of non running or drivable diesel duramax trucks because no one has the means, knowledge or capability to work on them. And the dealers all went under, no more OE support. Itll be real interesting. I know one thing, my all Mechanical p pumped HO 24v 6 speed Manual transmission truck will be driving down the road with no problems! I could even run it on waste oil motor, waste veggie oil, atf. If theres a diesel fuel shortage, no problem theres a lot of vehicles with engines and automatic transmissions will be sitting around with good burnable Oil in their engines! Try that with your 2020 dura-maxie pad truck. In all for keeping things simple, reliable, easy to maintain and fix. All this technology and sensors and modules and cheap plastic garbage isn’t making it easier on those of us that are technicians in the industry. Ive worked at the gm dealership, the dodge dealer, Been there done that. They aren’t going to get any better. We ad the consumer get what they cram down out throats. Take EV’s for example, bimbo biden and his democ-rat cronies cramming electric vehicles down our throats even tho its something we done need or want! Def, fluid now this is a funny one…it comes in a plastic jug that in a cardboard box. Wtf?!
