Xuhal Dual Chamber Head Gasket Tester Kit with 8.5 oz Testing Fluid

Features: Dual Chamber Anti-Backflow Design： The dual chamber structure with built-in check valve locks extracted gas samples and prevents coolant backflow between tests. This ensures consistent and uncontaminated combustion leak test results across every use, making it a reliable head gasket tester kit for both garage professionals and DIY diagnostics. Instant Color Change for Visual Diagnosis: Testing fluid shifts from blue to yellow within seconds when combustion gas are present in the cooling system. No interpretation required，the color change delivers immediate confirmation of blown head gasket, engine leak, or block test failure for fast and accurate head gasket leak diagnosis. Specifications: Material: durable plastic Color: blue Testing fluid capacity: 8.5 oz Test capacity: supports more than 50 tests Package Includes: 1 x Dual-Chamber Head Gasket Tester 1 X 8.5 oz Testing Fluid Notes: Manual measurement may cause slight size variations Color appearance may vary slightly due to lighting and display differences
