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. ## Features - This is the tightest bend radius hose on the market (custom molded heavy duty hose, better than factory hose) - Used to loop the heater hose outlets of your LS/LT engine water pump - Compatible with all LS or LT series engines from 1998 and newer - Used with vehicles that are no longer using the heater core - Includes 1 black rubber hose ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B013QNJ9SQ | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #272,651 in Automotive ( See Top 100 in Automotive ) #242 in Automotive Replacement Heater Hoses | | Brand | ICT Billet | | Color | Natural | | Customer Reviews | 4.8 4.8 out of 5 stars (680) | | Date First Available | August 11, 2015 | | Global Trade Identification Number | 00682384790816 | | Is Discontinued By Manufacturer | No | | Item Length | 1 Inches | | Item Package Quantity | 1 | | Item Weight | 2.08 ounces | | Item model number | 551699 | | Manufacturer | ICT Billet | | Material | Rubber | | Nominal Wall Thickness | 0.12 inches | | Number Of Pieces | 1 | | Part Number | 551699 | | Size | 1 Inch | | Specific Uses For Product | Vehicle use (LS/LT series engines, no heater core) | | UPC | 682384790816 | ## Product Details - **Brand:** ICT Billet - **Color:** Natural - **Global Trade Identification Number:** 00682384790816 - **Item Length:** 1 Inches - **Manufacturer:** ICT Billet - **Material:** Rubber - **Nominal Wall Thickness:** 0.12 inches - **Specific Uses For Product:** Vehicle use (LS/LT series engines, no heater core) - **UPC:** 682384790816 ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/61aWNXtWtPL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Real good part to do heater core bypass *by V***L on July 15, 2020* Work really good when you got to do a heater core bypass, you wont have your heater anynore but your radiator fluid will quite leaking if the heater core caused it to leak This makes sure it wont pinch the hoses also when you do it ### ⭐⭐⭐⭐⭐ Fits Nice on LS2 *by C***S on February 28, 2020* Fit perfectly on a LS2 GTO.
