The 6.7L Cummins engine, powering many Ram trucks from 2013 onwards, is a powerhouse. However, even robust engines benefit from upgrades, and the ATS Thermal Bypass Valve is a popular choice for enhancing performance and reliability. This guide will explore the benefits, installation, and considerations of upgrading your 2019 (or any 2013-current) 6.7L Cummins with an ATS Thermal Bypass Valve.
What is an ATS Thermal Bypass Valve?
The ATS Thermal Bypass Valve is an aftermarket upgrade designed to improve the engine's cooling system efficiency. The stock valve in the 6.7L Cummins can sometimes restrict coolant flow, leading to overheating, especially under heavy loads or in demanding conditions like towing. The ATS valve offers a larger flow area, allowing for more efficient heat dissipation and preventing overheating. This translates to better performance, increased longevity of engine components, and reduced stress on the system as a whole.
Why Upgrade to an ATS Thermal Bypass Valve?
Many owners choose to upgrade their 6.7L Cummins with an ATS Thermal Bypass Valve for several key reasons:
-
Improved Engine Cooling: The most significant advantage is enhanced engine cooling, reducing the risk of overheating, particularly during demanding operations. This is crucial for maintaining engine health and preventing costly repairs.
-
Increased Performance: By improving coolant flow, the engine operates at optimal temperatures, leading to increased performance and power output. This is particularly noticeable when towing heavy loads or driving in hot climates.
-
Extended Engine Life: Preventing overheating significantly contributes to extending the life of the engine and its critical components. This translates to long-term savings on maintenance and repairs.
-
Enhanced Reliability: A more efficient cooling system reduces the chances of engine failure due to overheating, increasing overall reliability.
How Does the ATS Thermal Bypass Valve Installation Work?
Installing an ATS Thermal Bypass Valve typically involves replacing the stock valve with the ATS unit. While straightforward for some mechanically inclined individuals, professional installation is often recommended. The process may involve draining some coolant, disconnecting hoses, and carefully installing the new valve. Detailed instructions are usually provided with the ATS kit. Always consult the manufacturer's instructions for your specific model year and engine configuration.
What are the potential challenges of installing an ATS Thermal Bypass Valve?
Installing an ATS Thermal Bypass Valve can present a few challenges, particularly for those without prior experience working on diesel engines. Some of the most common issues include:
-
Difficulty accessing the valve: The valve's location might make access difficult, requiring specialized tools or techniques.
-
Coolant leaks: Improper installation can lead to coolant leaks, requiring careful attention to detail during the installation process.
-
Incorrect torque specifications: Using the wrong torque settings when tightening bolts can damage the valve or surrounding components.
It's strongly recommended that individuals who lack mechanical experience seek professional installation to avoid any potential problems.
What tools are needed to install an ATS Thermal Bypass Valve?
You'll need a variety of tools for the installation, including:
- Wrenches (various sizes)
- Socket set
- Screwdrivers
- Coolant drain pan
- New coolant
- Possibly a torque wrench for specific bolts.
The exact tools will depend on the specific ATS kit and your vehicle's year and model.
Does installing an ATS Thermal Bypass Valve void my warranty?
Installing aftermarket parts like the ATS Thermal Bypass Valve can potentially void your manufacturer's warranty. This depends on the specific warranty terms and conditions and how the modification affects the engine's performance or reliability. Consult your vehicle's warranty documentation or your dealer for details.
How much does an ATS Thermal Bypass Valve cost?
The cost of an ATS Thermal Bypass Valve and installation varies depending on the retailer, location and whether you perform the installation yourself or have it done professionally. Always research and compare prices from reputable suppliers before purchasing.
Conclusion
Upgrading to an ATS Thermal Bypass Valve for your 2013-current 6.7L Cummins engine can offer several advantages, including improved cooling, enhanced performance, extended engine life, and increased reliability. However, careful consideration should be given to the installation process and potential warranty implications. For optimal results and to avoid potential issues, professional installation is often advisable.
