⏰Limited Stock 60% OFF🚗🧪 Combustion Leak Tester — Quickly Detect Exhaust Gas Leaks in Your Cooling System!
Dual-Chamber Testing Design
The two-chamber structure helps intercept coolant splash before it reaches the upper testing chamber, supporting a clearer sampling process.
Visible Color-Change Indication
Watch the indicator fluid as vapor passes through. A blue-to-yellow color shift can indicate possible combustion gas in the sample.
Simple Manual Bulb Operation
Use the squeeze bulb to draw a vapor sample through the tester. No batteries, electrical cords or air compressor are needed.
Cooling System Diagnostics
Helps investigate possible combustion gas leaks associated with head gaskets, cylinder heads and engine blocks.
