Uncovering 6.6 Duramax Diesel Problems of the 2006-2007 Chevy Silverado HD / GMC 6.6L LLY/LBZ Duramax

Here at ABCO Diesel Inc., we know that having a 6.6L LLY/LBZ Duramax engine in your 2006–2007 Chevy Silverado HD or GMC Sierra HD can be both a blessing and a curse. If you need assistance navigating these typical concerns, our skilled technicians are available to help you keep your vehicle in top shape.

Understanding 6.6 Duramax Diesel Problems

Lack of Emissions Control Parts

As much as GM tried to fix the problems with earlier models, some emissions control components are still missing from the LBZ/LLY Duramax common issues. The results of performance and fuel economy may be affected by this. Have faith in our staff to meet your unique requirements with an array of personalized solutions.

Turbocharger Troubles

This engine type frequently experiences issues with its turbocharger. Performance drops if oil gets into the turbocharger, and overboost or underboost might happen if the wastegate actuator fails. If your truck’s turbo isn’t working as it should, our experts at ABCO Diesel can diagnose and fix the problem.

Fuel System Failures

Fuel filter housing cracking can lead to fuel leaks, potentially causing engine damage. Additionally, the high-pressure fuel injection pump (CP3) is known to fail, resulting in power loss and stalling. At ABCO Diesel, we prioritize your fuel system’s integrity, using advanced diagnostic tools to address these issues swiftly.

Cooling System Challenges

Cooling system failures can spell disaster for your engine. We frequently see water pump failures leading to overheating, as well as radiator leaks. Our skilled mechanics will ensure your cooling system is in excellent shape, preventing overheating and extending the life of your engine.

Transmission Control Module Issues

The Allison transmission in the LLY/LBZ Duramax can experience problems with its transmission control module (TCM), resulting in harsh shifts or slipping gears. With our extensive knowledge of diesel mechanics, we’ll diagnose and fix any transmission issues to keep your vehicle running smoothly.

Additional Concerns

While less common, head gasket failures can occur due to overheating. Also, injector harness chafing may lead to intermittent injector failures. Our team is committed to addressing these potential issues before they escalate, ensuring your truck remains reliable.
