Can you pressure test a cooling system?
Pressure testing is used to check for leaks in the cooling system and to test the radiator cap. Shop air or simply the pressure generated by the coolant system can be used to measure the pressure and check for leaks. To test the system using a hand pump tester, make sure the radiator is full.
When pressure testing a cooling system how much pressure should be used?
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.
How do you test a thermostat and how is the pressure tester used to check the cooling system and the radiator cap?
How to Perform a Coolant Pressure Test
- Add Water If the Coolant Level Is Low.
- Remove the Radiator Cap.
- Connect an Adapter if Necessary.
- Tighten the Coolant Pressure Tester.
- Check the Radiator Cap for the System’s psi.
- Apply Pressure to the System without Exceeding the System’s psi by Pumping the Tester.
How do you find a coolant leak with a pressure test?
Use a radiator pressure tester to test for leaks. Install the tester on the neck of the radiator or the coolant reservoir, and pump until you reach the pressure marked on the radiator cap. Check around the engine, hoses, and radiator for leaks. Check inside the floor and console area for heater core leaks.
What are the requirements when a pressure cap is tested using a cooling system pressure tester?
Part 1 of 1: Pressure testing the radiator cap
- Material Needed.
- Step 1: Make sure the cooling system is not hot.
- Step 2: Remove the radiator cap.
- Step 3: Attach the radiator cap to the pressure tester adapter.
- Step 4: Attach the adapter with the installed cap onto the pressure tester.
