LML 11-16 Rear Engine Cover Coolant Plug

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.
