Trying to put a Duramax engine in

I don't want to buy a brand new engine to have it not fit into the truck
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hey there. This can be done for sure, but it isn’t a direct bolt in process. This is a project for someone with experience and passion for working on cars, or the budget to pay someone as much as a newer Duramax truck. The challenge with a project such as this is there will be many problems and challenges. The person who takes it on must enjoy creative problem solving to complete the project. You will need the motor, Allison transmission and the PCM and wiring harness for a Duaramax. Those are just the main items. Often times, the biggest expense is all the little items that are needed to complete the job. Hoses, clamps, gaskets, fabrication of brackets, engine mounts, etc. And then there are the unforeseen obstacles that are part of every project of this nature.

The cost of this sort of project will quickly add up. Unless you have some strong sentimental value with this rig, you will be able to purchase a newer truck for the same cost. The only exception to this is if you are doing the entire project yourself, which will take many hours of searching for answers, parts and time working on the truck. It is a very big project that should not be taken lightly.

There are two good sources for the purchase of a Duramax engine. A wrecking yard or the manufacturer. As I stated before, it is going to take a lot more than just the motor. To be completely honest, you will have to make the motor fit, nothing is going to fit directly. If you would like to have an expert fully inspect the car in person, a certified professional from YourMechanic can come to your car’s location to diagnose the vehicle and advice you on the best actions to take next.

Chevrolet has added the Duramax 3.0-liter turbo-diesel engine from the standard 1500 pickup as an option for the 2024 1500 ZR2. The 3.0-liter diesel engine offers fewer ponies but more torque than the huge 6.2-liter V-8 that comes standard on the ZR2.
3.0L DURAMAX TURBO-DIESEL

Get available best-in-class fuel economy for your Tahoe or Suburban, or add more range to your Silverado, with an available advanced 3.0L Turbo-Diesel engine.

The kit comes complete, and we mean complete with everything to turn the non-turbo 6.2L into a turbocharged diesel. The kit includes a new exhaust manifold and exhaust system, new air intake and high-flow air filter, and all the necessary hardware to make the conversion a bolt-on deal.
A Duramax swap can cost anywhere from $3,000 to $10,000, depending on the parts and labor involved. The most important factor in determining the cost of a Duramax swap is the transmission. A Duramax-swapped truck will need a new transmission that is compatible with the Duramax engine.
Overview: The 5.0L V8 Turbo Diesel stands alone between the smaller and larger diesel offerings in the pickup market.
Instead, it will clog up the fuel filter. And whatever amount of diesel that then makes its way to the engine will clog the fuel injectors, making them inoperable. This will result in the engine gumming up and seizing.
Share. A new year means a new truck for the outlet, and this year it`s a 2023 Chevy Silverado 1500 High Country 3.0-liter Duramax Diesel. Yeah, that`s a mouthful. A Chevy Silverado 1500 has been on my list for a few years due to its popularity and my interest in learning even more about the truck.
The 2023 Sierra 1500 now offers the second generation 3.0L Duramax Turbo-Diesel engine (standard on AT4 and available on SLE, Elevation, SLT, Denali and Denali Ultimate), and has been enhanced thanks to several key components and upgrades, including new steel pistons and a revised combustion bowl, returned turbo …
The original 6.2 L (379 cu in) diesel V8 was introduced in 1982 for the Chevrolet C/K and was produced until 1993.
Performing a diesel-engine swap isn`t easy. It takes time, knowledge, and patience. As any conversion specialist will tell you, the level of difficulty entirely depends on the make/model of the engine, the transmission being used, and the vehicle that`s being repowered.
The difficulty of performing a swap varies based on the combination of the auto body and the engine you are working with. Even the most straightforward swap, however, can be tricky. Each engine requires its own electronic system, and your transmission, fuel delivery, and steering may also need to be updated.
Fuel Economy: Diesel engines tend to be more expensive than gas engines, but they offer higher fuel economy ratings.
Performing a diesel swap usurps a big chunk of time. A DIY enthusiast with a good knowledge of diesels—and who is adept at welding, wiring, plumbing, and fabrication—can usually pull off a basic gas-to-diesel or diesel-to-diesel swap in 40 to 60 hours.
Since diesel fuel and regular gas have different properties, they should not be used in the same engine. Diesel fuel is much denser than regular gas, which means it can clog up a gasoline engine`s fuel system and cause major damage to the vehicle.
Because diesel fuel is denser, it can clog up a gasoline engine. Fortunately, there is little risk of damage to your vehicle if you happen to mistakenly fill it with diesel fuel. It is unlikely that this will harm the injectors, seals or other components.

The Chevrolet Silverado 1500, Ford F-150 and Ram 1500 are among the most popular vehicles sold in America, and each one now offers a diesel engine. But is it worth getting a diesel in a truck that isn`t meant for heavy-duty use?

the most relevant questions and answers related to your specific issue

Check engine light refuses to go off after engine replaced
ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.

Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.

To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.

Can front wheel drive car engine power rear wheel drive
ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.

My car engine shuts off after the engine is warm.
ANSWER : Hi There,
What you are describing sounds like an ignition coil pack that may be failing. Ignition coils are prone to this type of erratic functioning or heat cycling when they are beginning to fail due to the temperature fluctuations under the hood which ultimately cause them to shut down causing the car to only run after cooling down for 30-40 minutes. Ignition coils are coated with a varnish-like insulation that becomes brittle over time after being stretched then contracted repeatedly The insulation develops small fractures that open when heated and close when cooled. When open, they allow shorting of coil windings and decrease or eliminate the coil’s ability to function. This process will repeat itself continuously until the coil ultimately fails completely and must be replaced. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your ignition system.

Engine malfunction light, reduced engine power, engine powered down
ANSWER : Hi there. There are a lot of things that can cause this on your 2012 BMW M5. I usually start by scanning the computer for codes to see what comes up. If there are not codes then I load test the alternator and the battery to see if they are failing. Low voltage in the electrical system will cause this. If that is fine, then it is usually caused by a failing throttle body. I have seen a lot of these fail due to the motors in them hanging up. If the problem is only happening intermittently, this can make the issue hard to duplicate, but you can still have tests done on the car. If you are going to have this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to test the vehicle and diagnose the Engine Malfunction Light.

Engine Stalling
ANSWER : If you got a bad batch of fuel this may have caused the engine to run bad and stall as the fuel may have clogged the fuel injectors. If the fuel injectors got clogged then they may need to be cleaned or replaced. The fuel rail should be removed and cleaned out or replaced to get the debris out of the fuel rail. I would also try replacing the fuel filter. You can have the fuel tested for excessive debris or water in fuel to find out if this is what’s going on.

If you need some help with these checks, consider YourMechanic, as a certified technician can come to your home and diagnose the cause of your stalling issue firsthand. Best of luck.

Car engine turns off and dies when car is put in reverse or drive.
ANSWER : Hello there, many common faults will cause your 2008 Nissan Altima to shut off when put in drive or reverse. The first step in diagnosis is to check the transmission for leaks, and the fluid level and condition. Once the transmission fluid is checked most common faults are the torque converter, Idle air control valve, vacuum leaks, or a wiring harness fault. A qualified Technician such as one from YourMechanic will be able to diagnose your engine shuts off when put in drive and make any repairs required.

car runs great when engine is cold but dies when engine is warm
ANSWER : This sounds like there is a problem with the MAF (mass airflow) sensor. When your vehicle is cold, the PCM (Powertrain Control Module) is in what is known as open loop. Open loop is a preprogrammed program put in place for warm up. Closed loop is when the PCM begins using the sensors to adjust fuel ratio. The primary sensor the PCM uses to make decisions is the MAF. I’m leaning toward three possible problems here. The MAF may have been damaged during cleaning, the connector may have a bent pin from disconnecting and reconnecting its connector or the boot that connects the MAF to the throttle body has developed an air leak.

Before condemning the MAF, make sure there isn’t any unmetered air entering the motor after the MAF. This will confuse the PCM and things just won’t work correctly. Unmetered air is what we call it when there is a leak between the MAF and the throttle body.

Of course, make sure the MAF has been plugged in. If it is, disconnect the connector and inspect the pins. It is fairly common for the small electrical pins in all sensors to get bent over when reconnecting their connector.

It is very easy to damage sensors in the area of the throttle body when cleaning it. Carburetor cleaner can damage sensors. The one I am particularly worried about is the IAC valve. These can stick and cause many different idle control issues.

If this isn’t of any help to you, I recommend having a certified technician, such as one from YourMechanic, diagnose your stalling condition for an accurate repair.

Good luck!

I have a 2004 Dodge Ram 1500 5.7 Hemi engine V8
ANSWER : Hi There,

It sounds like you may have a couple of separate issues going on here. The idling problem may suggest you have a dirty or faulty idle air control valve. The idle air control valve monitors the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at idle. This valve is controlled by the vehicle’s computer and will adjust idle speed based upon other measurements such as engine temperature, intake air temperature and electrical system load or voltage. This is also an important function when starting the motor as it allows the motor to run and idle on it’s own once the motor fires. When you accelerate, the engine RPM increases, and as you let off the gas, the RPM slowly returns to the normal idling speed with the help of the idle air control valve making the transition from a higher RPM back down to idle speed while adjusting the air/fuel ratio constantly to allow this to happen smoothly. When the engine RPM drops below the normal range of about ~800 RPM, this often times will cause the engine to stall indicating a dirty or faulty idle air control valve.

Blue smoke coming from your exhaust generally means that the motor is burning the engine oil. This can happen for a couple of different reasons such as worn piston rings or leaking valve guide seals. When this happens, the engine oil is burned in the combustion chamber along with the fuel which is what generates the blue smoke coming from the exhaust. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your vehicle.
