UView Combustion Leak Tester Fluid 560500 – Blue Indicator Refill, Gasoline Yellow / Diesel Green, Fast Visual Detection

UView 560500 Combustion Leak Tester Fluid is a refill solution that gives a fast, visible color change to confirm combustion gases in a cooling system—yellow for gasoline and green for diesel.

This professional-grade test fluid is formulated for use with standard combustion leak testers to help identify head gasket failures, cracked blocks, or damaged cylinder heads early. Designed for both shop technicians and knowledgeable DIYers, the 560500 refill bottle provides a reliable visual reaction that makes engine cooling-system diagnostics straightforward and repeatable across gasoline and diesel platforms.

How quickly will I see a color change when combustion gases are present?

When combustion gases contact the UView fluid inside a compatible tester, the indicator reacts within moments to provide an unmistakable visual cue. The speed helps you confirm leaks during active testing without lengthy waiting periods.

• Typical reaction occurs in seconds to a few minutes depending on gas concentration.
• Blue base color transitions to yellow for gasoline-derived gases.
• Blue changes to green when diesel combustion gases are detected.
• Works reliably across a wide range of engine sizes and operating temperatures.

Will this fluid work for both gasoline and diesel engines?

Yes—UView 560500 is formulated for compatibility with combustion gases from both fuel types, letting a single bottle serve mixed-fleet diagnostics. The separate color responses let you distinguish gasoline leaks from diesel-driven combustion contamination instantly.

• One formula supports gasoline and diesel engine testing.
• Distinct color outputs reduce ambiguity during inspection.
• Suitable for passenger cars, light trucks, and many commercial engines.
• Designed for use with most standard combustion leak tester tools.

How is the fluid used in a typical leak test?

Fill the tester reservoir with UView fluid, pressurize the coolant system per the tool instructions, and sample the air from the cooling system through the tester. Any combustion gases will alter the fluid’s color, giving you a clear pass/fail signal and helping locate head gasket or structural failures.

• Pour into the tester’s sight chamber or reservoir as directed by the tool manual.
• Introduce system vapor/air through the tester while engine is running or as instructed.
• Observe color shift and compare to baseline blue for interpretation.
• Dispose of or recycle used fluid according to local regulations.

How many tests can I expect from one bottle?

Actual test count depends on the tester size and the volume required per inspection, but one refill bottle is enough for multiple diagnostic sessions. This economy makes the 560500 practical for regular shop use and periodic at-home checks.

• Multiple tests per bottle with small-capacity testers.
• Shop environments typically get the most use per refill.
• Concentrate on targeted testing to conserve fluid between inspections.
• Store tightly capped to maintain indicator stability between uses.

Who is this for? UView 560500 is intended for automotive technicians, mobile mechanics, and experienced DIYers who perform engine cooling-system diagnostics and need an unmistakable, color-based confirmation of combustion gas intrusion. It's well-suited for shops servicing mixed-fuel fleets, hobbyists troubleshooting engine performance, and anyone seeking a quick, visual method to identify potential head gasket or cylinder head problems before more invasive repairs.
