2011-2016 LML Coolant Bypass Kit

2011-2016 LML Duramax Coolant Bypass Kit.
Removes the faulty cheap blue or black hose kits that are well known to fail and leave you stranded with coolant puking everywhere. This kit routes coolant from thermostat housing to firewall/heater core connection with pre-installed billet quick connect fitting. Billet aluminum plug installs into rear engine cover coolant port, allowing removal of the OEM coolant hard pipe which allows for a cleaner look.
