2022-2024 Silverado & Sierra 1500 3.0L Duramax Thermal Bypass Valves

The stock thermostatic valve on your 2022-2024 Silverado or Sierra 1500 3.0L Duramax may be a small part of your truck's cooling system, but its failure can lead to big problems, and it's a very failure-prone component. The thermostat element inside the OEM valve can often get stuck closed, which blocks fluid flow to your Silverado or Sierra's transmission cooler, leading to high temperatures, limp modes, or even transmission damage. Tier One's selection of Silverado and Sierra 3.0L Duramax thermal bypass valves delete the thermostat element entirely so that your truck gets full-time fluid flow from its transmission to its transmission cooler. Get lower temperatures and improved reliability with a 3.0L Duramax thermal bypass valve today.
