What is a Pressure & Combustion Chamber Leak Test?
Your engine’s cooling and combustion systems work under high pressure and heat. Over time, leaks can develop in the head gasket, cylinder head, or engine block. A Pressure & Combustion Chamber Leak Test is a diagnostic procedure that helps us identify if exhaust gases are leaking into the cooling system , a common sign of serious engine issues.
Why is this test important?
- 🔧 Detect Head Gasket Failure – One of the earliest ways to confirm a blown head gasket.
- 🌡 Prevent Overheating – Leaks allow hot gases into the cooling system, causing overheating and engine damage.
- 💰 Save on Repairs – Catching leaks early prevents expensive engine rebuilds or replacements.
- ✅ Accurate Diagnosis – Instead of guessing, this test gives a clear indication of internal leaks.
How the Test Works
- Cooling System Pressure Test – We apply controlled pressure to your cooling system and check for drops in pressure that indicate leaks.
- Combustion Gas Detection – Using a chemical test fluid or electronic detector, we check for exhaust gases in the radiator or coolant reservoir.
- Result Interpretation – A change in fluid color (or detector reading) confirms combustion gases are entering the cooling system.
Signs You May Need This Test
- Persistent overheating
- Coolant loss with no visible leaks
- White smoke from exhaust
- Bubbling in the radiator or reservoir
- Milky oil (sign of coolant mixing with oil)
- Sweet smell from exhaust
