The 6.7L Cummins engine, powering many Ram trucks from 2013 onwards, is a robust workhorse. However, even this powerful engine benefits from upgrades to enhance performance and longevity. One popular modification is upgrading the thermal bypass valve, often with an ATS unit. This guide delves into the benefits, installation, and considerations of this upgrade, specifically focusing on the 2019 model year and beyond.
What is a Thermal Bypass Valve?
Before diving into the ATS upgrade, let's understand the function of the thermal bypass valve itself. This valve regulates the coolant flow within the engine block. Its primary role is to manage engine temperature during warm-up and operation, ensuring optimal operating conditions. A malfunctioning or inefficient thermal bypass valve can lead to several issues, impacting both performance and engine health.
Why Upgrade to an ATS Thermal Bypass Valve?
The stock thermal bypass valve in the 6.7L Cummins, while functional, may not be optimal for those seeking enhanced performance or reliability. The ATS thermal bypass valve offers several key advantages:
- Improved Engine Warm-up: The ATS valve often provides faster and more efficient engine warm-up, leading to better fuel economy and reduced wear and tear.
- Enhanced Coolant Flow: An upgraded valve can improve overall coolant flow, preventing overheating, especially under heavy loads or demanding conditions.
- Increased Reliability: The robust design of the ATS valve contributes to increased reliability and a longer lifespan compared to the stock component.
- Potential for Increased Power: By optimizing engine temperature management, the ATS upgrade can indirectly contribute to slight increases in power output.
What are the Benefits of Upgrading the Thermal Bypass Valve on a 2019 6.7L Cummins?
The benefits outlined above apply specifically to the 2019 model year as well. The 2019 6.7L Cummins, while a refined engine, still benefits from improved thermal management, especially for those who regularly tow heavy loads or operate their trucks in demanding environments. The quicker warm-up time translates directly into improved fuel efficiency and reduced emissions.
How Difficult is it to Install an ATS Thermal Bypass Valve?
The installation process varies depending on mechanical aptitude and access to tools. While some users might tackle it themselves, it’s a more involved process than a simple bolt-on modification. It often requires some mechanical knowledge and the right tools. Consider consulting a professional mechanic if you're unsure about the installation process. Improper installation could potentially damage the engine or void warranties.
Does an ATS Thermal Bypass Valve Void My Warranty?
Modifying your vehicle's components can potentially void manufacturer warranties. Whether or not an ATS thermal bypass valve upgrade voids your warranty depends on several factors, including your specific warranty terms and the dealer's policies. It's crucial to thoroughly review your warranty documentation and potentially discuss modifications with your dealership before undertaking this upgrade.
Are there any other upgrades I should consider alongside the ATS Thermal Bypass Valve?
Upgrading the thermal bypass valve is often part of a broader performance enhancement strategy. Other complementary upgrades for the 6.7L Cummins might include improved air intake systems, exhaust modifications, and tuning. However, remember to carefully research the compatibility and potential impact of each upgrade on your specific vehicle and warranty.
Conclusion:
Upgrading the thermal bypass valve with an ATS unit can offer noticeable benefits for the 2013-current 6.7L Cummins engines, including improved warm-up, enhanced coolant flow, and increased reliability. However, carefully weigh the cost, installation complexity, and potential warranty implications before proceeding. For owners seeking to maximize their engine's performance and longevity, the ATS thermal bypass valve upgrade is a worthwhile consideration. Remember always to consult the ATS instructions and seek professional assistance if needed during the installation process.
