Mishimoto Heater Core Bypass Hose Red For GM LS Swap

The Mishimoto Heater Core Bypass Hose for GM LS swaps provides a direct heater core bypass solution, delivering a clean, compact plumbing route that simplifies installation and improves packaging reliability for LS-powered projects.

Designed specifically for GM LS V8 applications, this Mishimoto silicone bypass hose eliminates the need to retain the factory heater core plumbing when performing an LS swap or building an LS racecar, offering a neater coolant circuit and reduced clutter in the engine bay.

• Silicone construction — Provides a flexible, durable connection that resists common degradation modes in coolant plumbing, helping maintain a consistent bypass path over time.
• GM LS V8 fitment — Engineered for compatibility with GM LS swap installations so you can bypass the factory heater core without custom-fabricating routing or adapters.
• Red finish — Visual identification for serviceability and a coordinated appearance in finished engine bays where component color-coding is preferred.
• Simplified installation — Serves as an off-the-shelf solution to remove heater core plumbing, reducing installation time and producing a cleaner final layout compared to jury-rigged alternatives.

Every aspect of this part is focused on functional value during an LS swap: straightforward integration, reduced plumbing complexity, and a purpose-built alternative to retaining or modifying the vehicle's heater core circuit.
