Normally, the liquid in the tool is blue but will turn yellow if there are combustion gases present in the cooling system, meaning there is a leak from the cylinders into the cooling system.įollow the instructions in the tools package.

This will pull cooling system air through the liquid inside the tool.

Now, squeeze the bulb on the tester tool.

With the engine cool, remove the radiator cap and install the block tester on the radiator neck.The test is simple and can be done with a "block tester" or combustion leak tester, a relatively inexpensive and easy-to-use tool. Often, this type of problem appears with symptoms like bubbles in the coolant, engine overheating, or even a rise in coolant level when you start the engine.

The combustion test can help reveal serious problems like a blown head gasket, a cracked block or cylinder head. Like a pressure test, a combustion test can be done at home or at the shop. If no leak showed up with the pressure test, it's time to do a combustion leak test. Watch the next video for some quick tips to check the cooling system, especially around the radiator.

If the cap can't hold pressure, the expansion valve is stuck open. The cap should hold pressure for at least 60 seconds. Then, pump the tester until the rated pressure is reached and stop.Otherwise, the cap relief valve isn't working. The radiator cap should release pressure when it goes past the cap's rated capacity. Pump the tool to a pressure exceeding the rated pressure capacity of the cap.Once the system is pressurized, start making a visual inspection of the system looking for a potential leak: around the radiator, heater core, hoses, water pump, engine core plugs, hose fittings, and engine gaskets.

Check your vehicle repair manual if necessary.

Start pumping air into the system until the tester gauge reads the system pressure as indicated on the radiator cap.

With the engine cool, remove the radiator cap and attach the tester hose to the radiator neck or the coolant recovery tank, depending on your particular vehicle model.

On some large models, the core may be installed towards the rear of the vehicle.Ĭheck each system hose, fitting, and connector for: The heater hoses are connected to hard tubing, usually on the firewall, on the passenger side, inside the engine compartment.

Upper and lower radiator hose and heater hoses.

Worn out or damaged pumps may start with a small leak long before you notice the problem. Look for cracks in the container itself and check the cap for leaks. Check the neck for nicks that may prevent a good seal. Inspect the cap for bad seals, tears or similar damage. Check for a broken or missing shroud that can lead to overheating and coolant loss. Make sure the front of the radiator is free of debris and dust that may prevent proper radiator operation. Check around the seams, where the core joins the tanks and the core area.
