Coolant plug to eliminate the coolant riser tube coming off of the rear engine cover on your LML Duramax. This allows you to eliminate the coolant tube to make more room under the hood or just simply clean up under the hood! This is needed in most applications when using S300 or S400 turbos or when doing a compound turbo setup. Includes high temp silicone o-ring for a long-lasting leak-free seal.
Our new 2013+ Cummins welded Aluminum Coolant Tank is the perfect part when more room is needed in the passenger side engine compartment for bigger or more turbos. Fully tig welded and pressure tested for the quality you have come to expect from our products. Includes a coolant level sensor and all necessary bungs/ports for a clean install. Mounts in the factory location for a clean look!
