What Is the Warranty on a 2007 Duramax Turbocharger?

There are a few things you should know when buying a turbocharger. First, you must ensure a warranty covers the product you purchased.

The warranty is in place to protect the original purchaser from any defects in the performance of the Stealth Turbocharger Products. In case of a defect, the warranty covers the entire product cost or a portion for one year. If the warranty period is exceeded, the manufacturer will credit the purchaser for the original purchase price or replace the product. The customer must contact the manufacturer within 60 days of purchasing the product. In such an event, the purchaser must provide the warranty claim form and ship the turbocharger to Calibrated Power for inspection.

In addition to warrantying the Stealth Series Turbocharger Products, Calibrated Power Solutions, Inc. also offers performance tuning. It provides tuning services for a variety of applications, including agricultural equipment. Recently, the company expanded into the agricultural sector, giving tuning for John Deere platform vehicles.

The limited warranty covers the product’s performance but does not cover damage caused by improper cleaning or other improper maintenance. The warranty does not cover parts or engine components that have undergone a powder coat or chrome finish. In addition, the warranty does not cover any claims subjected to power washing or bead blasting.

The warranty covers defects in materials and artistry. This warranty does not cover damage caused by abuse, misuse, or modification. Also, it does not cover the costs of shipping or labor to remove or replace defective parts. Therefore, it is essential to maintain a good maintenance schedule to maintain your equipment’s performance.

The warranty will not apply if parts are used in competitive activities or races. The warranty does not cover parts damaged through improper installation or break-in. In addition, the warranty does not cover parts that have been altered, modified, repaired, or serviced.


Before you get your turbocharger replaced, it’s essential to understand why it failed in the first place. Failure to diagnose the root cause of the problem can lead to an expensive repair. Here’s what to look for. In addition to detecting the failure, diagnostic tools will also reveal warning signs such as codes.

The first thing you need to do is to check the cylinder bore. Ensure that the cylinders are lined up correctly and are not bent. You can also perform a torque test to see if the turbocharger is working correctly. The cylinders are connected via a shaft.

Next, visually inspect the oil supply and drain lines. Check for kinks, cracks, and obstructions. Also, look for rust or corroded flanges. Also, check the exhaust manifold flanges. You may need to replace the exhaust manifold gasket.

The 6.6L LML Duramax was introduced in 2006. It met global emission regulations and was introduced to the market in 2006. It met the rules and was more powerful and reliable than its predecessor. These trucks were also equipped with a six-speed Allison transmission. They also came with more horsepower and torque than previous engines.

A turbocharger failure can cause several symptoms, including slow spool-up, low power, EGTs, and black smoke. If your turbocharger leaks boost, it can lead to an overheated engine. This can result in problems when towing and if you encounter any overheating.

The new turbocharger on the 2007 Duramax trucks has an improved oiling system. It has a dedicated feed for the turbocharger, which allows for faster oil delivery and increased pressure at the turbo. Enhanced oiling provides lubrication for the turbo, which contributes to lower engine temperatures and increased durability. In addition, new Duramax pickups come with an oil pan made of laminated steel and an aluminum upper section. The aluminum section adds strength to the pan, while the steel lower section provides damping.

The P2263 diagnostic trouble code signals a problem with the turbocharger. This code can be caused by various causes, including a faulty turbo bearing or a worn-out turboshaft. Furthermore, the turbocharger may have obstructions that cause the vanes to malfunction.


When you install a new turbocharger in your 2007 Duramax truck, you are taking responsibility for the safe use of your vehicle. Aftermarket parts can solve these problems and improve longevity and performance. However, some features may have defects and require repair. Here are some things to look for when purchasing a new turbocharger.

GMC’s LBZ and LLY motors are at fault for this problem. These engines are commonly used in medium-duty trucks and pickups. This problem occurs when the primary web cracks around the crank journal. If this happens, your vehicle can suffer from a loss of horsepower or a turbocharger failure.

The engine management system knows what boost pressure should be, and if it goes below that level, it will set a DTC or diagnostic trouble code. The code P0299 indicates that the boost pressure is below the expected level. It can occur multiple times in one or two critical cycles, but you can still replace the turbocharger.

There are numerous problems with LLY-powered trucks, including overheating. The radiator and fan in the front of the turbocharger are too small to cool the engine adequately. This causes an overheating problem, which can lead to blown head gaskets. However, GM addressed this problem with the 2004 1/2 redesign. The company also added an EGR cooler, which helps prevent the engine from overheating.

The stock turbo on Duramax trucks can produce over 500 RWHP, but they require tuning and supporting modifications to handle the extra power. However, some owners want more power and are looking for more reliable performance. These owners may also be looking for EGT control under load. For these reasons, they may be considering a factory turbo replacement.

If your 2007 Duramax truck is sluggish, it may indicate that your turbo has a problem. The engine codes will tell you what’s wrong. If the problem is not engine related, the turbo may have a sensor problem. The sensor may be gunked up or dirty. A dirty turbo can also lead to problems with the engine’s performance.
