The 6.7L Cummins engine, a powerhouse found in many heavy-duty trucks and vehicles from 2013 onwards, is known for its robust performance. However, even this workhorse can benefit from upgrades, and the ATS Thermal Bypass Valve is a popular choice among owners looking to enhance engine longevity and efficiency. This guide delves into the benefits, installation, and considerations of upgrading your 2019 (and other model year) 6.7L Cummins with an ATS Thermal Bypass Valve.
What is a Thermal Bypass Valve?
Before we dive into the specifics of the ATS upgrade, let's understand the function of a thermal bypass valve. This crucial component regulates the flow of coolant within your engine's cooling system. Its primary purpose is to ensure the engine reaches its optimal operating temperature quickly and efficiently, preventing excessive wear and tear. A malfunctioning or inefficient thermal bypass valve can lead to issues like:
- Slow warm-up times: Resulting in increased emissions and reduced fuel efficiency.
- Overheating: Potentially causing significant engine damage.
- Uneven engine temperature: Leading to inconsistent performance and potential component failure.
Why Upgrade to an ATS Thermal Bypass Valve?
The stock thermal bypass valve in your 6.7L Cummins might be adequate, but the ATS upgrade offers several key advantages:
- Improved Cold Weather Performance: The ATS valve helps your engine reach optimal operating temperature faster in cold climates, crucial for preventing excessive wear during cold starts.
- Enhanced Engine Protection: By more precisely controlling coolant flow, the ATS valve reduces the risk of overheating, safeguarding your engine's vital components.
- Increased Fuel Efficiency: Faster warm-up and more efficient temperature regulation contribute to improved fuel economy.
- Durability and Reliability: ATS valves are built with high-quality materials designed to withstand the demands of heavy-duty use.
ATS Thermal Bypass Valve Installation: What to Expect
While the installation process is relatively straightforward, it's crucial to have the necessary tools and some mechanical aptitude. Consider consulting a professional mechanic if you're unsure about any aspect of the installation. The process generally involves:
- Disconnecting the battery: A safety precaution to prevent electrical shorts.
- Draining coolant: This is necessary to access the thermal bypass valve.
- Removing the old valve: This might require removing other components for access.
- Installing the ATS valve: Carefully following the manufacturer's instructions.
- Refilling the coolant system: Using the correct type and amount of coolant.
- Bleeding the air: To ensure proper coolant flow throughout the system.
How Does the ATS Valve Differ from the Stock Valve?
The key difference lies in the design and materials. ATS valves often utilize superior materials and a more precise design, resulting in improved performance and reliability compared to the stock unit. This improved precision leads to better temperature regulation and a more efficient overall cooling system.
Is the ATS Upgrade Worth the Cost?
The cost of the ATS upgrade varies depending on the retailer and any additional parts you might need. However, the potential benefits – improved engine protection, enhanced fuel economy, and quicker warm-up times – often outweigh the initial investment, especially for those who regularly operate their trucks in demanding conditions or extreme temperatures.
What are the potential downsides of upgrading?
While generally considered a beneficial upgrade, there are potential downsides to consider. Incorrect installation can lead to further problems, and the higher initial cost is a factor for some owners. There's also a small risk of incompatibility, although this is rare with reputable brands like ATS.
Where can I purchase an ATS Thermal Bypass Valve?
ATS parts are typically available through various automotive parts retailers and online stores specializing in heavy-duty truck parts. Always verify the compatibility with your specific model year and engine before purchasing.
What maintenance is required after installing the ATS valve?
Regular maintenance, as recommended by the manufacturer, is crucial. This includes periodic coolant flushes and inspections to ensure the valve continues to function optimally.
This detailed guide provides comprehensive information regarding the ATS Thermal Bypass Valve upgrade for your 2013-current 6.7L Cummins. Remember to always consult the manufacturer's instructions and, if unsure about any aspect of the installation, seek professional assistance. Proper installation ensures the longevity and improved performance this upgrade offers.
