Mishimoto LS Heater Core Bypass Hose Red MMHOSE-LSHB-RD
MM Silicone Hose - Heater
Radiator Coolant Hose Kit
If youre doing an LS swap, chances are you wont be running a heater core in the platform youre swapping. Whether youre doing an LS swap or building your LS-powered racecar, the Mishimoto Silicone GM LS V8 Heater Core Bypass Hose is the easiest and cleanest solution for bypassing your heater core. Our bypass hose is constructed from heat and pressure resistant 5-layer silicone and 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 the preferred method, as opposed to blocking off the ports. This allows coolant to flow for your thermostat to function properly and avoid overheating. As with all our products, the Mishimoto Silicone GM LS V8 Heater Core Bypass Hose is backed by our signature Mishimoto Lifetime Warranty.

Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
