As part of the 2020 Chevy Silverado 1500 and 2021 Chevy Tahoe, GM released the 3.0-liter Duramax diesel, which is a small block inline-six. Now a significant feature of this engine should be known to prospective buyers. design of a Duramax diesel.
In addition to the Sierra 1500, the Yukon, and Suburban, this engine officially powers the GMC Sierra 1500, GMC Yukon, and Chevy Suburban in 2020 and 2021. It does not appear on either of GM’s full-size SUV versions (more to follow).
The engine generates 277 horsepower and 460 lb-ft of torque at just 1,500 RPMs in the half-ton Silverado and was designed specifically for these vehicles.
It is also equipped with a low-pressure EGR system, variable geometry turbocharging, and a lightweight aluminum block.
In all seriousness, inline-6 diesel engines are leading the way in new technologies. There is one notable exception, however.
Would you mind telling me what that one thing is? People pointed out that after 150,000 miles the oil pump belt resided in oil and needed to be thoroughly inspected. The fact that the belt is surrounded by oil rather than a chain or gear drive raises some concerns despite the fact that the belt is positioned in a semi-permanent position. It is important to note that the belt must be dropped to be serviced. Those were not typos. A belt inspection is required after 150,000 miles, meaning the transmission must be dropped. This has been criticized by many people.
Due to the frequent occurrence of this issue, an engineering interview was sought with the GM. This engine’s belt cannot be replaced unless the transmission is removed. Since the engine was created, this engineer has explained why the belt was selected. design of a Duramax diesel.
In a nutshell
Even though it’s ridiculous to remove the transmission to examine the belt and it costs around $1,000 to have the belt checked by a mechanic, the inspection is only one time.
Our favorite isn’t this one either. In our opinion, the benefits of diesel outweigh its disadvantages. The Silverado 1500 achieves an incredible fuel economy of nearly 30 MPG.
The belt will be studied closely by GM and they will assess whether they need to redesign it or substitute another belt. In that case, we’ll let you know. Just be alert when shopping at the moment.
In order to take the Duramax beyond 550 RWHP, more fuel is needed, and the aftermarket can build injectors with high flow and factory-like reliability. Injectors are fitted with EDM-cut nozzles for increased flow rates between 30.00% and 500.00% (and more if you have air) are offered by two of the most prominent manufacturers of the Duramax common-rail fuel system. design of a Duramax diesel.
These comprehensive injectors are a great choice for those looking to reach 600 horsepower and beyond. You get the most performance-oriented injectors on the market when Bosch parts and equipment are used in their production and testing.
