What is radiator pressure testing?
What We Do Radiator pressure testing is a common procedure we carry out to identify any leaks in your vehicle’s cooling system. To carry out this test, we use a pressure tester to pump air through your vehicle’s cooling system. If the pressure tester’s gauge holds steady, the system won’t have any leaks.

How long does a radiator pressure test take?
Generally, it attaches to the radiator where the radiator cap goes, and you pump it by hand until the pressure on the gauge matches the pressure that is written on top of the radiator cap. Typically on a modern vehicle this pressure is between 13 – 16 psi. Let the vehicle sit with this pressure for 20 – 30 minutes.

What is a cooling system pressure test?
A cooling system pressure test is a procedure used to determine if engine coolant (sometimes called antifreeze) is leaking somewhere in the cooling system. When the system develops a leak, it is not always visible.
Where does coolant leak?
A leak on the outside of the engine may spring from a weak spot or tear in a radiator hose, at the hose connections, from a hole in the radiator, from a bad seal at the water pump, in the heater core underneath the dashboard, and so on.
Why does coolant drop?
It is essential that the amount of coolant in the system be kept full. But sometimes the coolant level drops - either due to overheating or to a leak in the system. In a cooling system pressure test, a technician uses air to pressurize the system, and a pressure gauge to read the effects.
Why does my coolant light come on?
When the coolant level sensor detects the loss, a warning light on the dashboard will come on to alert the driver that the coolant level is low. Sometimes the coolant loss is due to a leak somewhere in the system. The leak may leave a puddle of fluid under the vehicle or inside the engine compartment. But not always.
What is the cooling system of an engine?
The cooling system makes sure that the engine runs within a consistent temperature range without overheating. In the cooling system, a mixture of coolant and water is circulated through the engine block to absorb excess heat. It is routed out of the engine and through the radiator, ...
How is coolant moved?
The coolant is moved through the system by the water pump, driven by a serpentine belt on the front of the engine . And the temperature is regulated with a thermostat placed in the path of the coolant. It is essential that the amount of coolant in the system be kept full.
What temperature does a late model engine run?
An engine in a late model vehicle is designed to run somewhere between 195 and 220 degrees. But the fluid in the cooling system can rise well in excess of 220 degrees when the engine overheats. This produces steam that will cause severe injury from scalding if the system is opened when hot and under pressure.
