HUMMER H1 HEATER CORE UPGRADE KIT ('97.5-'02) 5744783-KIT

Replace your leak prone heater core with our upgrade kit. Our kit replaces the factory heater core and its rigid soldered tubes with our custom billet aluminum sealing plate, aluminum heater core and flexible silicone hoses. AM General realized the flaw in the '97.5 - '02 factory Heater Core and changed to a system that uses silicone hoses in place of the soldered tubes in 2003. Now you can upgrade your '97.5 - '02 to the more reliable '03-'06 style heating system.
