More about this item : GM LS V8 Heater Core Bypass Hose, Mishimoto Silicone Black

The Mishimoto Silicone GM LS V8 Heater Core Bypass Hose is the cleanest and easiest solution for bypassing your heater core, whether you’re building your LS-powered racecar or doing an LS swap.

Constructed from 5-layer silicone that is heat and pressure resistant, it tapers from 3/4" to 5/8” to fit the “in” and “out” ports on your water pump.

Using a bypass hose instead of blocking off the ports allows coolant to flow for proper thermostat function and helps avoid overheating.

The Mishimoto Silicone GM LS V8 Heater Core Bypass Hose is backed by our signature Mishimoto Lifetime Warranty.
