# Mishimoto LS Heater Core Bypass Hose Black If you're doing an LS swap, chances are you won't be running a heater core in the platform you're swapping. Whether you're 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. - Bypassing instead of blocking water pump ports allows coolant to flow to thermostat and avoids overheating - Allows you to bypass heater core - Fits all GM LS engines This Part Fits: Year Make Model Submodel 2008-2009 Buick LaCrosse Super 2006-2007,2009-2015 Cadillac CTS V 2010-2015 Chevrolet Camaro SS 2014-2015 Chevrolet Camaro Z/28 1998-2002 Chevrolet Camaro Z28 1998-2002 Chevrolet Camaro Z28 SS 2012-2015 Chevrolet Camaro ZL1 2013 Chevrolet Corvette 427 2008 Chevrolet Corvette 427 Limited Edition Z06 2003 Chevrolet Corvette 50th Anniversary Edition 2003 Chevrolet Corvette 50th Anniversary Edition Pace Car 1997-2013 Chevrolet Corvette Base 2010-2013 Chevrolet Corvette Grand Sport 1998 Chevrolet Corvette Indianapolis 500 Pace Car 2006-2013 Chevrolet Corvette Z06 2011 Chevrolet Corvette Z06 Carbon 2009-2013 Chevrolet Corvette ZR1 2006-2009 Chevrolet Impala SS 2006-2007 Chevrolet Monte Carlo SS 2014-2017 Chevrolet SS Base 2005-2006 Chevrolet SSR Base 2006-2009 Chevrolet Trailblazer SS 1998-2002 Pontiac Firebird Formula 1998-2002 Pontiac Firebird Trans Am 2009 Pontiac G8 GXP 2005-2008 Pontiac Grand Prix GXP 2004-2006 Pontiac GTO Base 2008-2009 Saab 9-7x Aero ## Details - **Price:** 66.81 CAD - **Vendor:** Mishimoto - **Type:** Hoses ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 66.81 CAD | In stock | ## Images - Photo - Primary - User 1 - User 1 - Logo Image --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/mishimoto-ls-heater-core-bypass-hose-black) > Updated: 2026-06-27
