UView Combustion Leak Test Kit for Engines — Dual-Chamber Tester with 16 oz Color-Changing Reagent, Gas & Diesel

When an engine loses compression or coolant becomes contaminated with combustion gases, diagnosing the source quickly can save time and money. The UView 560000 kit offers a handheld, chemical-based test that reveals whether combustion gases are present in the cooling system, helping you identify leaks in head gaskets, cylinder heads, or engine blocks without disassembling the engine. Its dual-chamber design reduces false positives by filtering alkaline particles, while the included 16 oz. reagent clearly changes color to indicate gas exposure.

How does the dual-chamber design improve test accuracy?

The dual-chamber layout separates the sampling zone from the reagent chamber so alkaline particles and contaminants are filtered before they reach the color-changing fluid. This reduces the chance of the fluid shifting color from non-combustion sources and helps you trust the readout. The clearer results make follow-up diagnostics and repair decisions faster.

• Two-chamber flow path isolates contaminants from the reagent
• Reduced false positives from alkaline residues in coolant
• Stable reagent exposure for reliable visual indication

What do the color changes mean for gasoline vs. diesel engines?

The tester fluid is engineered to produce distinct color shifts depending on the combustion gas chemistry. For gasoline engines, the reagent shifts from blue to yellow when combustion gases are present; for diesel engines, it shifts from blue to green. These clear, separate color outcomes let you interpret results quickly at the workbench or roadside.

• Blue to yellow = combustion gas detected in gasoline engines
• Blue to green = combustion gas detected in diesel engines
• Remains blue = no detectable combustion gas exposure during the test

How is the kit used and what’s included?

The kit arrives with the dual-chamber tester, one 16 oz. bottle of UView testing fluid, and straightforward instructions so you can run the test in minutes. You fill the reagent chamber, connect the tester to a radiator or coolant reservoir, and observe the color over a short test period while the engine idles or is pressurized as directed. No specialized tools or engine tear-downs are required for the initial diagnosis.

• Dual-chamber tester ready to connect to radiator or overflow
• 16 oz. color-changing reagent provided
• Step-by-step instructions to complete a test in minutes

How quickly will I know if there’s a combustion leak?

A single test typically takes only a few minutes from hook-up to result once the engine is in the recommended state (idle or pressurized per instructions). The clear color transition gives an immediate visual cue so you can decide whether further mechanical inspection or repair is needed. Because the kit is portable, you can test on the vehicle without removing major components.

• Fast hook-up and short observation period
• Immediate visual color cue for quick decision-making
• Portable for on-vehicle testing and quick diagnostics

Who is this for? The UView 560000 Combustion Leak Test Kit is aimed at vehicle owners, independent mechanics, and fleet technicians who need a fast, affordable way to screen for combustion gases in the cooling system. It’s useful for routine trouble-shooting of overheating, unexplained coolant loss, or discolored coolant and for workshops that want a reliable, repeatable diagnostic step before committing to invasive repairs. The kit provides a practical first check that can direct further testing or confirm the need for gasket, head, or block service.
