Garbage factory heater bypass valve broke so I tried to cobble together a loop from the parts store to bypass the whole heater loop temporarily. The loop I cobbled together fit poorly as it had to be so big due to having a size adapter coupler in the middle. This loop dropped right in, eliminated the extra fitting I needed before and is nice and snug to the water pump. Zero leaks and just reused the factory hose clamps. ## Frequently Bought Together - ICT Billet LS Heater Core Bypass Hose Coolant Crossover LS1 LM7 LR4 LQ4 LS6 L59 LQ9 LM4 L33 LS2 LH6 L92 L76 LY2 LY5 LY6 LC9 LFA LH8 LMG LS3 L98 L9H L20 L94 LZ1 L99 L96 LC8 L77 551699 - PQY 36" Braided Throttle Cable Kit Compatible with 97-07 Chevrolet/Chevy LS1 Engine 4.8L 5.3L 5.7L 6.0L - Lokar TCB-40LS1 LS1 Throttle Cable Bracket for GM Throttle Body with 3" Linkage Cam --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/257707818-ict-billet-ls-heater-core-bypass-hose-coolant-crossover-ls1](https://www.desertcart.co.th/products/257707818-ict-billet-ls-heater-core-bypass-hose-coolant-crossover-ls1) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-28*
