HPS Reinforced Silicone Heater Core Bypass Loop Coolant Hose LS LT LQ

As LS engines are becoming increasingly popular to swap, we saw an opportunity to develop a product catered to LS powered enthusiasts. Whether your car or truck came with an LSX, or you are swapping one in, the HPS LS Heater Bypass Loop is a necessity for those who plan to bypass the cabin heater. This easy to install loop eliminates concerns about air pockets that can develop when capping off your heater lines.

This is the lowest profile heater loop on the market, measuring in at only 3 inches tall. We reinforced this hose with 4 layers of polyester between each layer of premium quality silicone. The HPS LS Heater Bypass Loop will install on any LS family engine (LS1, LT1, LQ9, etc) with 5/8" and 3/4" heater supply and return ports. Embossed stainless steel hose clamps are included for easy installation.
