๐๐งช Combustion Leak Tester โ Quickly Detect Exhaust Gas Leaks in Your Cooling System!
Stop Guessing.
Check for Combustion Gas in the Cooling System.
A manual automotive diagnostic tool designed to help identify possible combustion gases entering the cooling system using visible color-change test fluid.

๐ Get Another Clue Before Replacing Parts
Overheating, coolant loss, bubbling in the reservoir, or unexplained cooling-system pressure can have several possible causes. This tester gives you an additional screening method during diagnosis.
Overheating Investigation
Use the test as one part of a broader cooling-system inspection.
Unexplained Coolant Issues
Helpful when combustion-gas intrusion is one of several possible causes being considered.
๐ Draw Vapor Through the Fluid โ Watch for a Reaction
Vapor from the cooling system is drawn through compatible test fluid. A noticeable color change can indicate that combustion gases may be present.
- ๐ต Start with the reference color. The supplied fluid is described as blue in its normal state.
- ๐งช Draw vapor through the chamber. The sample passes through the test fluid during pumping.
- ๐ Watch for a visible shift. A reaction may indicate combustion-gas contamination.
- ๐ง Use the result as diagnostic support. Confirm findings with other mechanical tests when needed.

๐จ Squeeze-Bulb Operation โ No Power Source Required
The rubber hand bulb manually draws vapor through the tester, so the diagnostic process does not depend on batteries, cables, or an external pump.
Manual Control
Squeeze the bulb repeatedly to pull the sample through the chamber.
No Batteries
Keep it ready in the garage without worrying about charging or battery condition.

๐งช Clear Dual-Chamber Design for Easier Observation
Transparent chambers make it easier to monitor the fluid during testing, while built-in level markings provide a visual fill reference.
Clear Body
Observe fluid color without opening the tester.
Level Reference Marks
Helps guide fluid placement before beginning the test.

๐ง Fill. Position. Pump. Observe.
Follow the instructions supplied with the compatible test fluid and your vehicle's safe cooling-system service procedure.

๐ Useful When Combustion Leakage Is One Possible Cause
The tester is designed to support troubleshooting when checking whether combustion gases may be entering a compatible engine cooling system.

๐ฆ Tester Only or Tester + 250 mL Fluid
Tester Only
Includes the transparent combustion leak tester and manual rubber squeeze bulb.
Tester + Fluid
Includes the tester, squeeze bulb, and one 250 mL / 8.45 fl oz bottle of compatible test fluid.

๐ง A Positive Reaction Is a Clue โ Not the Entire Diagnosis
Combustion gases in the cooling system can be associated with several engine-sealing problems, but this tester by itself does not identify the exact failed component.
What It Helps Detect
Possible combustion-gas presence in the cooling-system vapor.
What It Doesn't Identify Alone
The exact location or mechanical cause of an internal engine leak.
โ ๏ธ Never Open a Hot or Pressurized Cooling System
- ๐ฅ Allow the system to reach a safe service condition. Hot coolant and steam can cause severe burns.
- ๐ซ Never remove a pressurized radiator or reservoir cap. Follow the vehicle manufacturer's cooling-system service procedure.
- ๐งช Handle test fluid according to its label. Avoid skin or eye contact and keep the container closed when not in use.
- ๐งค Wear suitable protection. Gloves and eye protection are appropriate when servicing cooling systems.
- ๐ถ Keep test chemicals away from children and pets. Store the fluid securely after use.
- ๐ง Stop if you're unsure. Seek professional service if the vehicle condition or safe test procedure is uncertain.
Quick FAQ
What does this tester check for?
It is designed to help detect possible combustion gases entering a vehicle's cooling system.
How does the test work?
Cooling-system vapor is drawn through compatible chemical test fluid. A visible fluid color change may indicate the presence of combustion gases.
Does a color change automatically mean a blown head gasket?
No. A reaction can indicate combustion-gas intrusion, but the exact cause may involve a head gasket, cylinder head, block, or another sealing issue. Further diagnosis may be needed.
Does it need batteries?
No. Vapor is drawn through the tester using the included manual rubber squeeze bulb.
Is the test fluid included?
It depends on the selected option. The Tester Only version does not list fluid, while the Tester + Test Fluid version includes one 250 mL / 8.45 fl oz bottle.
Can I use any test fluid?
Use fluid specifically intended for combustion-gas cooling-system testing and follow that fluid manufacturer's instructions.
Can I test the car immediately after driving?
Never open a hot or pressurized cooling system. Follow the vehicle manufacturer's safe service procedure and allow the system to reach an appropriate condition before accessing it.
Can the tester tell me exactly what engine part has failed?
No. It is a screening and diagnostic-support tool. It can help indicate possible combustion-gas leakage, but it does not independently identify the exact failed component.
Who is this tool suitable for?
It is suitable for automotive technicians, garages, experienced DIY users, and vehicle owners performing appropriate cooling-system diagnostic checks.
๐ Get a Clearer Clue Before You Start Replacing Parts.
Use visible color-change testing to help determine whether combustion gases may be entering the cooling system โ then use that information to guide the next diagnostic step.
๐งช Draw the Vapor. Watch the Fluid. Diagnose With More Confidence.
