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

For an LS swap or building your LS-powered racecar, the Mishimoto Silicone GM LS V8 Heater Core Bypass Hose offers the cleanest and easiest solution for bypassing your heater core.

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.

The preferred method for bypassing the heater core is using a bypass hose instead of blocking off the ports.

This method 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 the signature Mishimoto Lifetime Warranty.
