Should You Warm Up A Diesel Engine?

Diesel Engines are great for pulling power and fuel efficiency, but only when they are up to operating temperature. What is the best way warm them up to operating temperature. Should you let them idle, high idle, or drive them? @AdeptApe on Venmo or [e-mail] on PayPal for donations, thank you so much for supporting the channel!

[@grasscutter88]

you wait for the oil pressure to change? what does that mean?

[@clarkstonguy1065]

@@grasscutter88 Oil drains back to the oil pan when the engine is off. When it is really cold out and the oil is the consistency of honey or even peanut butter it takes a while for the oil pump to suck it up and pump it through the engine. It could be well over a minute if it is like -40 degrees out. So on an older vehicle with an actual reliable oil pressure gauge waiting to increase engine speed above idle until it moves form zero to normal is a really good idea. These days most gauges in cars and light trucks are more like fancy idiot gauges that mostly read normal all of the time unless something is really wrong, so it may not be as reliable of a method.

This is one of the biggest benefits of electronic controls. It limits fuel rates and rpms when coolant and oil temps are low.

In a nutshell. The fastest warmup time with the least amount of engine load is what it boils down to. That mindset/advice has proved to be good rules to live by for me. Two other key things he said about those cars is nothing killed the engines faster than a bad thermostat and the engine running two cold and never ever over full the automatic transmission.

[@oby-1607]

An old trucker taught me to never put it under a load until you see the gauge move. If the gauge doesn't move, don't move the truck. 1000 rpm warmup after initial startup and idle settles down.

[@corywillbanks6348]

I work in the gas compression industry on cat g3600's. The most important thing on them is that your oil temp never exceeds the jacket water temp in fact the ecm will shut the engine down if there isn't enough differential between the two. Since the pistons are oil cooled they don't want the hotter oil to expand them any larger than the cylinder liners. As a general rule of thumb I never start to drive or load anything until coolant temp is up to 160 degrees. Good videos man it's nice to watch someone with a good head on their shoulders

[@cwj9202]

Cory, I am puzzled by this part, "...oil temp never exceeds the jacket water temp...", because there have been excellent industry tests demonstrating the benefits of engine oil temperatures exceeding 212° F, the primary one being evaporation of water from the oil.

[@corywillbanks6348]

Chad Jessup yessir it does promote evaporation but for the oils we run at temperatures that high the viscosity is usually out of spec also at high temps the oil will break down quicker and when you're talking a 240 gallon oil change we try to squeeze every penny out of it. In certain applications like running on landfill gas they will raise the temperature of the jacket water to promote more evaporation due to the corrosive nature of the gas it will form acids in the crankcase when it mixes with moisture but most all of our gas isn't corrosive so we run lower temps, jacket water at 190 and engine oil at 180. We also run a straight 40w oil to help with oil life as multi viscosity oils (15w-40 etc) have a shorter life comparatively.

[@peterronson2823]

Amazing to hear your comment. We run g3600 generator sets and ended up cracking the cylinder liner due to this very fact ....oil temp over Jacket water temp .. Adem alarms but does not shut down engine when this happens

[@corywillbanks6348]

Peter Ronson awesome where are you located? What size of engines are you running? It may be because ours is a different application but it will shut down if oil exceeds water by 7 degrees and will alarm at three degrees,

[@peterronson2823]

We've got a pair of g3612's and a g3616 in full cogeneration application. Toronto, Ontario. Ours when it failed cracked the liner scuffed up the piston but fortunately all the parts stayed in the cylinder. I can't remember what finally shut down the engine but it was not the temp differential alarm in the ADEm. My memory is that shutdown has a long timer too...so damage is already done. We added external valves on the JW circuit after the failure to make sure the JW temp stays high and gets up to temp quickly.

Great video, follow strictly on warming up my small diesels for a minute before rolling out. Thanks

[@joealbert7773]

Pretty much spot on. No need for extended warm-up, but you should take a minute or two before you start to load the engine. One thousand rpm for idling is the proper way if you have extended idle time. Also, as you move the vehicle you should remember that the transmission, rear axles, and wheel bearings need to be warmed so their lubricants can come up to temperature.

[@user-jp7rk1uf2n]

I have seen a lot of wheel seals taken out in cold weather.

[@JC-gw3yo]

Whole heartedly agree with you on an easy warmup on diesels. When our engines are started, let oil pressure build at minimum RPM and after a few minutes, drive off under empty load until close to operating temperature. Never push a cold engine. Up here in Montana, we see -40 F. We use oil pan and block heaters. The newer 5-40 synthetic oils are also a big advantage for sustained cold driving. PS.. you will have to keep your window open and breathe outside until your heater starts throwing heat to keep your windshield from fogging up.... you won't experience that in AZ Haha

Very sound advice. On the older diesel trucks and equipement, we used to idle them for long periods to warm up, and once started for the day they stayed running, often idling for hours at a time. With the modern diesels, it's pretty much fire them up, idle for 30 seconds or so, then drive or operate conservatively until up to operating temperature. That's pretty much in line with your advice.

[@Jack-qn4vt]

Dariusz D, correct :)

[@KingOath]

Did you even listen to the video? The pressure may be there but the engine isn’t properly lubricated until the oil warms and thins and begins to flow through the engine at the right rate

[@bramshobbyshop757]

Dariusz D concerning gasoline engines: gas engines use an open/closed loop fuel trims. When cold, a gas engine will operate under open loop, meaning the ECU commands the engine to run with the injectors dumping fuel into the combustion chambers in an effort to increase overall operating temperatures. Gasoline is a solvent: so when in open loop, the engine runs extremely rich. If left to idle before the ECU commands the engine to go into closed loop (14.7:1 air fuel ratio), the cylinders will wash down, causing premature wear. If it's super cold, say around 10 below 0, then yes, let it idle, but if not, jump in and take off. The lack of immediate oil pressure in the cold will not negate the loss of lubrication by letting a gas engine idle in open loop. Carburated engines of course are a different story, but with EFI, it's a whole new story.

[@edpettit6563]

Getting your oil up to operating temp before stressing the engine is what's most important in warming up a gasoline engine I think we all agree. The best way to do that is to start driving as soon as you start your engine but under very light load conditions until your oil temp is up to its operating range. In the winter it might take 20 or 30 minutes for that to happen just letting it idle. So cold oil combined with rich idle conditions means minimal lubrication. Idling a gas engine for more than a minute will shorten the life of your engine without a doubt. I know this goes against what most of us were taught but if you think about it, it will be obvious to you. Plus if your one of those tree hugging people your catalytic converter will not be able to change CO2 into O2 until it is heated up either. So not only are you damaging your engine warming it up by idling in an evironmentalists eyes you may as well be clubbing baby seals.

I have a John Deere 4045 Diesel engine that starts wide open on an irrigation pump, it is equipped with block heaters and electric oil pump so it is at 180 degrees and 30lbs of oil pressure before it starts.

I love the 2nd part and will be looking forward to it . That's a failure I haven't run into before . As for warm up I've always figured to get oil pressure , wait a few seconds more then slowly bring it up to about 1000rpm until I've got enough air to release the brakes and then ease out . It's a very subjective discussion without a defined end . well done .

I start my 12 Valve and then open my driveway gates. Move truck outside using low gear and idle rpm. Park truck and then close the gates. Drive away normally and don't get on it until coolant temp is normal. If towing heavy it is warmed up until temp registers and then I take it easy for 5 miles until trans and rear end warms up.

[@Kaegis]

Our marine SOP's stated 2mins idle, then easy load use till engine temps rise then full load after that. If it was a generator, it would be 2mins idle, then 1800rpm no load till temps rose, then bring on load. Our main propulsion diesel engines (PDE) were 2mins idle, 850rpm no load till temps rose, then full use. Keep in mind that our PDE's were 90Litre MTU V16, so 1000rpm was midrange operation.

[@zacharyprovance3128]

Growing up on the family farm, we would always start our tractors up in the fall/winter and idle them for about 4 or 5 minutes and then bump them up to around 1300 to 1500 RPM to speed up the heating process. After about 15 to 20 minutes or so we'd go to work. We put anywhere from 8k-15k hard hours on all of our machines and they never needed a rebuild (short of our cotton picker but it was already heavily used when we bought it).

Many years ago in the U K a company called Coventry Climax (nice) made an aluminium fire pump engine, small and hand portable. The same engine became a successful race engine as it had lightness and power. As you mentioned with regard to the standby generator, it was not exactly the same. The pump engine had larger tolerances for max oil flow immediately. If it used twice the oil and wore out quickly- so what- got to put that fire out!

[@basvanderhoek9293]

I have a 1982 Citroen CX Diesel in Vancouver Canada. the oil is 20-50 all year round. I must be doing something right, its still going. What I do not do, is drive any distance shorter than 12 kilometer. Watching your video made me feel good, thanks.

[@pauljanssen2624]

It's a good thing to warm up a diesel engine depending on how cold it is depends on how long you warm it up allowing the oil to get to the turbo and the Pistons to warm up so you don't end up with piston slap and wrist pin knock from not warming up your diesel it's not a bad idea to read the owner's manual you'll find a lot of tips

[@alexstromberg7696]

It takes less than a second for the oil to get there

[@lcee6592]

I worked in a NASCAR shop for 7 years. ANYTIME we started a “cold” engine, the oil was heated (to 210 deg) and circulated thru the engine before starting it. Not letting any engine warm at least 3-5 minutes raises the chance of excess bearing wear/ damage. While today’s synthetic oils do flow better at “9 degrees” than older conventional oil, it does not flow that good. 1-2 minutes warm up is not enough in below freezing temperatures. All engine oils have an optimum temperature operating range. Room temperature and colder is not in that range.

[@fredg8199]

JFC. This is not a nascar engine! Anyone who lives in a cold climate (Like Canada!) will have enough common sense to gradually warm the engine after the initial 2 minutes. For example. If hooked to 140,000 pounds, starting my day in Btfk nowhere I would open hood, check the oil and other fluids, do a visual for leaks, check steering, Then I would start engine, do a proper walk around, check tires, etc, come back to the engine area, do another quick visual, close the hood! At this point you can start moving WITH LIGHT THROTTLE INPUT! You do not Jeff Gordon the thing and hit the rev limiter even if at 180 -200 °F, that is just plain stupid! Axles, tires, wheel bearings must be gradually warmed too! At -40°F you could easily rip apart a driveshaft or do unnecessary wear to the tranny or diffs. To make a long story short...This is not grandpas 6v71 using straight 30 weight conventional oil. We run modern electronically controlled engines. :)

[@aronderksen7055]

I live in Canada and we use block heaters on all of our equipment. We have several aftermarket circulating heaters and those things can actually get the engine up to operating temperature. We have to actually be careful about it because if you leave it plugged in to long it will boil all the water out of the engine. To be fair these things draw over 1500 watts and do not include any sort of max temp switch.

[@michaelpperrault]

Thanks for the info, someone tried telling me that I should leave the engine at a low idle until warm. I've usually increased rpms over a 1000 almost from the get go, and it takes a few minutes to "air up", by then I'm going down the road . You touched on idling in cold climates, I drove for an outfit out of Yellowknife, NWT. The idle on their trucks was preset at 1500 rpm to maintain heat, both for the engine and for the sleeper.

Every new car owner as well. Any car I drive, if it's first thing in the morning, I always let it warm up. Start it up, rev it to about 1800 RPM after 1 minute, wait until the engine temperature needle gets to about 20%. At that point, the engine's almost done warming up and I can go.

[@bretolson279]

@@electric7487 lol I think I would let it just idle until the temperature gauge is about half way to normal operating temperature, then go drive it

Just a note, many of the large Gen sets I have worked with have an electric oil pump that will pre-lube the engine before it starts. I often wish I had this on my trucks!

[@Smiling_mike]

Enjoying your destruction segments! Education thru explanation and visual aides work for me, thanks!

[@Grabatire]

It would have been good to mention that a piston is 'cam ground' during it's manufacturing process. Meaning it is slightly oval shaped and not perfectly round until it has reached, or nearly reached, operating temperature. A cold piston will have some piston slap on the skirt which can result in piston damage if put under even a light load too soon. A short skirt will suffer more damage than a long skirt. Just something to keep in mind.

[@billpurves6297]

The C series cat engine went to a 3 piece piston. The piston head and skirt are separate and held together with the wrist pin. The skirt is built perfectly round and according to cat can be put under full load as soon as it comes off high idle. The old 2 cycle Detroit also used the 3 pice piston. They were well known for standing up to cold weather operation.

[@mandavaler]

I usualy wait until the temp gauge has actually moved above the C to drive off

[@michaelbenoit248]

mandavaler, on my 7.3 when I’m creeping after idling for a few minutes, then when I’m driving, I can feel the motor bog down a little then take off @ no throttle on torque. Then once it’s done that then I’m good. Every motor is different but that’s what I do. When it’s a little warmer above 70 I let it idle a little about a few minutes. Luges oil additive helps reduce dry starts & all that stuff. But I treat it like it doesn’t have it in it. When it’s under 60 I let it idle about 5 minutes then slowly drive off, then once I feel it’s warmed up then I give it a little more go-go, rarely NEVER full throttle. Until about 10 minuets later after warm.

[@bdjm8595]

Good info here!!! On my 03 Dodge I always plug it in and have added a trans heater and a battery tender to the plug on the bumper. Makes for a very happy start and drive away on cold mornings !!!

[@richardblanchard2743]

Your destruction of the week video brought out an old memory. I had a pickup that someone had worked on before me and they forgot to tighten the bellhousing bolts. As I drove the truck I would hear a strange clicking sound as the transmission moved around flexing the flywheel. Eventually the torque converter bearing failed, leaking out the transmission fluid. The flywheel didn't come apart but was cracked pretty bad.

[@k.kristianjonsson4814]

So in the end it is a compromise: Get up to operating temperature as soon as possibly, but not in the brutal way. Start the engine, idle for a minute or two, then put some load on the engine to rise the temperature faster by driving away, but under light or moderate load, increase load as the engine temperature goes up. Another thing, modern oil doesn't get thick. SAE 5-40 or 0-40.

[@AdeptApe]

+Kristian Jonsson The most widely used oil over here is 15W40 and it is a bit thick when cold. Those wider range multigrade would definitely flow much better in the cold, that is for sure.

[@smoadia85]

That will be 0W-40 or 5W-40. Those oils pour point is around -30 deg C or lower on average.

[@ilikeboost4764]

Kristian Jonsson exactly what I've heard. And it makes sense.

[@Romans--bo7br]

Kristian Jonsson..... He is NOT addressing little diesel engines in pickup trucks, cars, etc..... we do NOT use 5-40 or 0-40 oil in Heavy Duty diesel engines in HD trucks.... semis, Off hwy mining trucks, Heavy Equipment, etc, etc. The main focus Of The Video is on heavy-duty diesels in Semis or class 7&8 heavy-duty trucks (all diesel) in general.

[@gregpenner2876]

I tend to watch the oil pressure gauge and bump up the RPMs to match the cold start pressure as it warms up till about 1K RPM. Don’t forget that there’s other components that need to warm up as well like trans,rearends,and hubs. I’ve literally blown out hubcaps before when the vent was too stiff and couldn’t vent properly and I started driving too fast too soon at -20°f. Also cold scoring is a thing.

[@user-jp7rk1uf2n]

I've seen drivers take out wheel seals starting out too fast at 20 below zero.

[@blacksheep6888]

As a qualified diesel fitter, I agree with what you have said, well explained

[@chasl3645]

I would think you'd want battery backups for critical loads. That would give gen sets a few minutes to warm up. They could also buffer loads so generators can be a bit smaller.

[@SeriousSchitt]

Shit, now you tell me dude. I've been cold starting and idling my diesel engine for a quarter of an hour, sometimes half an hour, before taking off, thinking I was doing it the world of good. I've been doing that for the last 16 years in the same truck!

[@murphtahoe1]

Great video with solid information! A question for you would be if this is transferable in regards to proper warm up for a non commercial diesel such as a 7.3 Powerstroke? Thanks for the great videos!

[@surveyguyor8958]

sure. On mine, I drive it soon after starting, but I just run at low rpm's and slowly. it's not just the engine, but the cold transmission, and rear axle. everything is cold and stiff and need to warm up, it all puts a load on the engine, but there's no way to warm it up other than to drive it, just take it slow and no high rpms for a mile or two

[@Q_Branch]

Failure is such a good teacher.

[@TheBirdandEagle]

Thank you. Simple and to the point. Excellent.

[@Mikheno]

There was a great article a few years back, on an RV web page, about warming up your diesel pusher before going all out. Pretty much what you said. They recommended taking off right after oil pressure came up (one minute?) but go easy for the first few miles. Once coolant temps bumped up a little (noticeable rise on the gauge) you were good to go. From that point on run like you normally would. If it's really cold (teens or lower) plug in the block heater for an hour or so before starting. Either way don't sit at a cold idle waiting for the engine to warm up. Preheat the engine or take right off but get it warm as soon as possible. JMO

[@mountfields]

When cold, I always crank the engine over for 10 seconds or so with the fuel pump OFF to prime the engine with oil, so when I turn it to start the bearings aren’t dry......... (perhaps unnecessary, but that’s what I was always told)...

[@joeking1019]

makes perfect sense

[@apatriot1762]

Perfect example is my 2013 dmax. It has factory high idle. When I remote start it runs for about 30 seconds or so before the idle jumps up until it reaches temp. It’ll do this any day colder than 70 degrees or so

[@wilk128]

In the winter, I unplug it, start it, increase the rpm. Then i go back inside, where it's warm, and have another cup of coffee or two, before going out and hooking up the trailer.
