The 6.7L Cummins engine, found in many Ram trucks from 2013 onwards, is a powerful workhorse. However, like any engine, it benefits from upgrades that enhance performance and longevity. One popular upgrade is the ATS Thermal Bypass Valve. This guide delves into the benefits, installation, and considerations surrounding this popular modification for your 2019 (or any 2013-current) 6.7L Cummins.
What is an ATS Thermal Bypass Valve?
The ATS Thermal Bypass Valve is an aftermarket upgrade designed to improve engine efficiency and reduce wear by optimizing coolant flow. The stock thermal bypass valve can sometimes restrict coolant flow, leading to potentially higher engine operating temperatures, especially under heavy loads or in extreme conditions. The ATS valve addresses these issues by allowing for more efficient coolant circulation, ensuring the engine operates within its optimal temperature range. This can translate to improved fuel economy, reduced engine strain, and enhanced overall performance.
Why Upgrade Your 2019 6.7L Cummins with an ATS Thermal Bypass Valve?
Several key benefits drive the popularity of the ATS Thermal Bypass Valve upgrade:
- Improved Engine Cooling: The enhanced coolant flow provided by the ATS valve helps prevent overheating, particularly crucial during towing or demanding driving situations.
- Increased Fuel Efficiency: By maintaining optimal engine operating temperatures, the ATS valve can contribute to better fuel economy.
- Reduced Engine Wear: Lower operating temperatures lessen stress on engine components, leading to prolonged engine lifespan.
- Enhanced Performance: While not a direct horsepower adder, the optimized cooling contributes to consistent performance, preventing power loss due to overheating.
- Easier Installation (Generally): Compared to some other engine modifications, the ATS Thermal Bypass Valve installation is often considered relatively straightforward.
How Does the ATS Thermal Bypass Valve Work?
The stock bypass valve regulates coolant flow based on engine temperature. The ATS valve typically offers a more efficient and responsive system, often involving improved valve design and materials. This leads to quicker and more consistent temperature regulation, preventing extreme temperature fluctuations. The specific mechanisms vary slightly depending on the specific ATS model, but the core principle remains consistent: optimized coolant flow management.
What are the Potential Downsides of Installing an ATS Thermal Bypass Valve?
While the benefits are generally considered significant, it's important to note potential drawbacks:
- Cost: The ATS Thermal Bypass Valve is an aftermarket upgrade, and its cost needs to be factored into the decision.
- Installation Complexity (in some cases): While generally considered relatively easy, some installation may require mechanical skill. Improper installation can lead to issues.
- Warranty Considerations: Installing an aftermarket part might void or affect your vehicle's warranty, depending on your warranty terms and the installer's expertise.
Is it Difficult to Install an ATS Thermal Bypass Valve?
The difficulty of installation varies depending on your mechanical aptitude and experience. While many consider it a relatively straightforward process, some individuals may find it more challenging. Consult detailed installation instructions and videos provided by ATS or reputable sources before undertaking the installation yourself. If unsure, professional installation is always recommended.
Does the ATS Thermal Bypass Valve Void My Warranty?
Modifying your vehicle with aftermarket parts can impact your warranty. Check your warranty terms carefully. In some cases, installing an ATS Thermal Bypass Valve might void or affect your warranty coverage, especially if the installation is done incorrectly and causes damage. Always consult with your dealership or warranty provider if you have concerns.
What are Some Alternatives to the ATS Thermal Bypass Valve?
While the ATS Thermal Bypass Valve is a popular choice, other aftermarket cooling system upgrades exist. These might include different types of bypass valves, improved radiators, or enhanced coolant additives. The best option depends on your specific needs and budget. Researching alternative options will help you make an informed decision.
Conclusion
The ATS Thermal Bypass Valve upgrade presents a compelling option for owners of 2013-current 6.7L Cummins engines seeking improved engine cooling, fuel efficiency, and overall performance. While cost and installation factors should be considered, the potential benefits, especially for those frequently towing or driving in demanding conditions, can justify the upgrade. However, always prioritize proper installation to avoid potential warranty issues or damage to your vehicle. Remember to consult detailed installation guides and weigh your options before proceeding.
