Complete silicone heater hose kit for a 2006-2009 Trailblazer SS (TBSS) 6.0L.
This kit is designed to replace the failure prone OE heater line assembly found on the '06-'09 TBSS. This kit fully eliminates all OE hoses and hard lines and replaces them with sections of silicone heater hose and appropriate adaptive fittings. The sections of heater hoses included are 36 inches in length and may be cut to fit depending on how the installer chooses to route the hoses. Your kit includes two quick connect heater adapter fittings that install directly onto the heater core inlet and outlet. Your kit also includes a tee that allows for the small diameter OE steam vent hose to be retained with use of our heater hose kit.

Why Choose Silicone?
There are several advantages to silicone hoses beyond just their cosmetic aspect. Primarily the higher resilience to high underhood heat (such as in a turbocharged application, or even just the additional heat from long tube headers). They do not harden up or dry rot from excessive heat, these have an operational heat range of -40 to 475 degrees. These hoses will maintain their pliability and flexibility throughout their entire lifespan. Furthermore, the multi-ply silicone can handle much higher pressures than traditional rubber, these hoses are burst tested to 250psi and can sustain operational pressures up to 72.5psi (about 4.5 times the standard cooling system pressure). Silicone is much more impervious to oil based contaminants, and will not break down like rubber when exposed to oil or other lubricants. When compared to rubber hoses, the service life of silicone is unparalleled, these would likely be the last set of hoses you would ever need to purchase for your truck.
