Description
Product Overview
The Rogiosa Transmission Cooler Thermal Bypass Valve is engineered for durability and precise temperature control. Constructed from high‑grade polished metal, the valve offers superior corrosion resistance and a robust response to temperature changes. It features a standard threaded inlet connection and a thermal bypass mechanism that opens or closes based on coolant temperature, ensuring optimal flow to the transmission cooler. With a two‑port design, the valve fits seamlessly into existing cooling circuits and is supplied as a single unit with a one‑year manufacturer warranty.
Usage
This valve is a direct replacement for the OEM thermal bypass valve in a range of GM and Cadillac vehicles, including 2014‑2020 GMC Sierra and Yukon, 2014‑2019 Chevrolet Silverado, 2015‑2020 Suburban and Tahoe, and 2016‑2018 Cadillac CT6. It is installed in the transmission cooling system to regulate coolant flow during cold starts, heavy towing, and extreme ambient temperatures. The valve’s automatic operation eliminates the need for manual adjustments, making it suitable for both daily commuters and professional drivers who demand reliable transmission performance under load.

FAQ
Is this valve compatible with my 2018 Chevrolet Silverado?
Yes, the Rogierra thermal bypass valve is a direct replacement for the factory valve on 2014‑2019 Chevrolet Silverado models.
Do I need any special tools to install the valve?
Installation requires basic hand tools such as a wrench and screwdriver. The threaded inlet connection is designed for standard fittings, making the process straightforward for most DIY mechanics.
How does the thermal bypass function protect the transmission?
The valve remains closed when coolant temperature is low, allowing the transmission to warm up quickly. As temperature rises, the valve opens, diverting excess coolant to the radiator and preventing over‑cooling, which safeguards internal components.
What warranty does Rogierra provide?
The product includes a one‑year limited warranty covering defects in materials and workmanship.
Can this valve be used for heavy‑duty towing applications?
Absolutely. The valve’s automatic regulation helps maintain optimal transmission temperature during prolonged high‑load conditions, making it ideal for towing and heavy‑payload scenarios.
