Review: Can reuse - Perfect for co test in head gasket Review: The OG - The UView leak tester kit comes with this. It works well & is a lot quicker than performing a cylinder leak down test. Basically this is for telling a customer they are better off replacing the engine or the vehicle. For the DIYer, a leak down tester may be more thorough, but this will tell you if you need to replace the head gaskets, along with being able to observe other issues within the spark plug tube / combustion chamber in the cylinder. ## Features - POSITIVE LEAK PROOF: Detects leaks by changing color, ensuring accurate diagnosis of engine issues - VERSATILE USAGE: Effective for both gasoline and diesel engines, adapting to multiple vehicle types - COLOR CHANGE INDICATOR: Blue fluid turns yellow for gasoline, green for diesel, confirming leak presence - ENGINE MAINTENANCE TOOL: Essential for detecting combustion leaks, enhancing maintenance routines - EASY APPLICATION: Simplifies leak detection with visible color change for efficient engine troubleshooting ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000NPEXOQ | | Best Sellers Rank | #240,099 in Automotive ( See Top 100 in Automotive ) #97 in Fuel Leak Detectors #2,539 in Diagnostic, Test & Measurement Tools | | Brand | UView | | Customer Reviews | 4.7 4.7 out of 5 stars (151) | | Date First Available | August 12, 2004 | | Is Discontinued By Manufacturer | No | | Item Weight | 1 pounds | | Item model number | 560500 | | Manufacturer | CPS | | Manufacturer Part Number | 560500 | | Model | CPS UVIEW 560500 Replacement Combustion Leak Tester Fluid | | Product Dimensions | 2.7 x 2.7 x 8.9 inches | ## Images ![UView 560500 Combustion Leak Tester Fluid Replacement, Color Change Indicator, Gasoline and Diesel Compatible, Positive Leak Detection, Blue to Yellow for Gasoline, Blue to Green for Diesel - Image 1](https://m.media-amazon.com/images/I/518k3zoQiYL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Can reuse *by S***T on December 12, 2025* Perfect for co test in head gasket ### ⭐⭐⭐⭐⭐ The OG *by A***4 on February 19, 2026* The UView leak tester kit comes with this.
