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

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 resistant to heat and pressure, this bypass hose tapers from 3/4" to 5/8” to fit the “in” and “out” ports on your water pump.

Bypassing the heater core with a bypass hose is preferred over blocking off the ports, as it allows coolant to flow for your thermostat to function properly and helps avoid overheating.

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