đăEasy InstallationăComes with braided hose and O-ring fittings to ensure leak-free installation, no need to dismantle the head when installing
đăDESIGNăOur coolant bypass kit adds an auxiliary thermostat that, unlike other brands, works based on temperature rather than overpressure, this prevents damaging coolant pressure buildup by ensuring consistent temperatures across all six cylinders, Solve problems before stress becomes a problem
đăFunctionăThe rear cylinder of Cummins lacks coolant flow, so the coolant temperature is the highest. This can cause excessive pressure in the cooling system, especially the rear of the valve body, and blow out freeze plugs or smaller diameter plugs under the bonnet from the outside, causing failure. Coolant Bypass is one of the most important additions you can make to improve the reliability and longevity of your Cummins platform
đăAfter-salesăAfter you receive the product, if you have any questions, please feel free to contact our customer service, our factory has a 90 day warranty
Make sure all cylinders are at the same temperature
