UnderDog Diesel 2011-2016 LML Duramax Coolant Bypass Kit

Replace your leaking, cheap “Chinese” kit hoses with the ultimate bypass solution from UnderDog Diesel. The blue/black hoses in low-quality kits are known to blow the brass crimps apart, leaving you stranded. Our kit eliminates that failure point with premium components built to last.

Features:

• Preformed rubber hose routes coolant from thermostat housing to firewall/heater core connection
• Billet quick connect fitting for a secure, leak-free connection
• Billet aluminum anodized plug installs into rear engine cover coolant port
• Removes the need for the OEM coolant hard pipe
• Includes coolant cap for metal hard line
