The 6.7L Cummins engine, powering many Ram trucks from 2013 onwards, is a powerhouse known for its torque and reliability. However, even this robust engine can benefit from upgrades to enhance performance and longevity. One popular upgrade focuses on the engine's thermal management system: the ATS Thermal Bypass Valve. This guide delves into the benefits, installation, and considerations of upgrading to an ATS Thermal Bypass Valve for your 2013-current 6.7L Cummins, specifically addressing a 2019 model.
What is an ATS Thermal Bypass Valve?
The ATS Thermal Bypass Valve is an aftermarket upgrade designed to improve the efficiency of your 6.7L Cummins's cooling system. The stock system can sometimes struggle to maintain optimal operating temperatures, especially under heavy loads or in extreme conditions. This can lead to increased wear and tear on engine components and reduced performance. The ATS valve addresses this by precisely controlling coolant flow, ensuring the engine operates within its ideal temperature range. This precise control helps prevent overheating in demanding situations and promotes quicker warm-up times in cold weather.
Why Upgrade to an ATS Thermal Bypass Valve?
Several key benefits drive the popularity of the ATS Thermal Bypass Valve upgrade:
- Improved Engine Life: By maintaining optimal operating temperatures, the ATS valve reduces thermal stress on engine components, significantly extending their lifespan.
- Enhanced Performance: Consistent operating temperatures contribute to peak engine performance and efficiency.
- Reduced Wear and Tear: Preventing overheating minimizes damage to vital engine parts like the head gasket, pistons, and connecting rods.
- Faster Warm-up Times: The valve's precise control aids quicker warm-up, improving fuel efficiency and reducing emissions during cold starts.
- Better Fuel Economy: Maintaining optimal temperature improves combustion efficiency, potentially leading to slightly better fuel economy.
What are the potential downsides?
While the benefits are generally considered significant, there are potential downsides to consider:
- Cost: The ATS Thermal Bypass Valve is an aftermarket upgrade and will cost more than sticking with the stock system.
- Installation Complexity: While achievable by mechanically inclined individuals, installation might require specialized tools and some mechanical aptitude. Improper installation could lead to issues.
- Warranty Considerations: Installing aftermarket parts may void or affect your vehicle's warranty. Check your warranty specifics before proceeding.
How Does the ATS Thermal Bypass Valve Work?
The ATS valve improves upon the stock system by providing more precise control over coolant flow. It does this by utilizing a thermostat that opens and closes at more precise temperature thresholds compared to the factory unit. This allows the coolant to bypass the radiator when the engine is cold, allowing for faster warm-up, and directing more coolant through the radiator when the engine is hot, promoting optimal operating temperatures.
Is the Installation Difficult?
Installation complexity varies depending on your mechanical skills. While some users successfully install the ATS valve themselves, it's a more involved process than a simple bolt-on. It typically requires some familiarity with automotive systems and the use of specialized tools. Consult detailed installation instructions from ATS or seek professional installation if needed.
Will this void my warranty?
Modifying your vehicle with aftermarket parts can impact your warranty. Check your warranty details carefully, and consult with your dealership or the manufacturer before installing the ATS valve. In some cases, using reputable parts and careful installation might mitigate warranty concerns, but it's crucial to understand your rights and responsibilities beforehand.
What other upgrades complement the ATS Thermal Bypass Valve?
Optimizing your 6.7L Cummins involves a holistic approach. The ATS valve works well in conjunction with other performance upgrades, such as:
- Improved Air Intake System: A better air intake system improves air delivery, leading to better combustion and performance.
- Exhaust System Upgrades: Exhaust system upgrades can reduce backpressure and increase power.
- Tuner Upgrades: Engine tuners can optimize fuel delivery and timing to complement the improved thermal management.
Conclusion:
The ATS Thermal Bypass Valve represents a solid upgrade for enhancing the performance, longevity, and efficiency of your 2013-current 6.7L Cummins. By providing precise control over engine temperature, it addresses a common weakness in the stock cooling system. However, consider the costs, installation complexity, and potential warranty implications before proceeding. Carefully weigh the benefits against these factors to determine if the ATS Thermal Bypass Valve is the right upgrade for your vehicle. Remember, always consult professional resources and manuals for proper installation and maintenance.
