OEM quality level of fit to replace your old rubber hoses but are made of Silicone for better pressure resistance and overall performance. Review: Good alternative - Helpful since I didn't have time to replace the heater core. Good for a strong temporary hold time a fix is available. Review: Perfect Fit on an 04 Silverado - I purchased a rubber hose on fleabay meant for this and after installing it squished in the middle. I already got silicone hoses to replace everything so I gave this a shot, it is a much better fit. Just like with any silicone hose that you must clamp, wrap the outside with electrical tape or something similar a couple of times to prevent scaling. ## Features - LS / LT Swap (Gen III, IV, V) - 5/8" and 3/4" Hose Ends - 2 Clamps included - Silicone Hose - Better pressure resistance and overall performance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08JQ78GNJ | | Best Sellers Rank | #263,680 in Automotive ( See Top 100 in Automotive ) #201 in Automotive Replacement Heater Hoses | | Brand | Corvette Envy | | Brand Name | Corvette Envy | | Color | Black, Silver | | Customer Reviews | 4.7 out of 5 stars 151 Reviews | | Item Length | 0.63 Inches | | Item Weight | 0.11 Kilograms | | Manufacturer | Corvette Envy | | Material | Silicone | | Material Type | Silicone | | Outside Diameter | 0.63 Inches | | UPC | 854006006166 | | Unit Count | 1 Count | ## Product Details - **Brand:** Corvette Envy - **Color:** Black, Silver - **Item Length:** 0.63 Inches - **Item Weight:** 0.11 Kilograms - **Manufacturer:** Corvette Envy - **Material:** Silicone - **Outside Diameter:** 0.63 Inches - **UPC:** 854006006166 ## Images ![LS Heater Core Bypass Hose Coolant Crossover by Corvette Envy for LS LSX LS1 LS2 LS3 LS6 LS7 LQ4 LQ9 LT1 LT4 - Image 1](https://m.media-amazon.com/images/I/71WP64UTsyL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good alternative *by A***R on November 30, 2025* Helpful since I didn't have time to replace the heater core.
