How To Pressure Test A Cooling System
How to pressure test a cooling system. A cooling system pressure tester can be installed in place of the radiator cap. The rest of the cooling system comprises a small expansion tank and a hose connecting to the radiator. Pressure Testing for Strength and Leak Tightness.
This guide explains why systems are pressure tested and how to safely pressure test using nitrogen. There are two methods for pressure tests. Typically on a modern vehicle this pressure is between 13 16 psi.
My goal was to apply this AC-derived knowledge and equipment to pressure-testing the cooling system of the Lotus engine. Turn the connector lock counter-clockwise and listen to the system releasing its pressure. Pressure Tests for the Cooling System.
You apply pressure on the cooling system with the test kit. At SLAC pressure tests must be hydrostatic unless pneumatic tests can be justified. To test the system using a hand pump tester make sure the radiator is full.
A hydrostatic test is performed by using water as the test medium whereas a pneumatic test uses air nitrogen or any non-flammable and non-toxic gas. The first test of the cooling system is done when the engine is cold. It also shows how to calculate the test pressures in.
Shop air or simply the pressure generated by the coolant system can be used to measure the pressure and check for leaks. 12 Jan 11 2013. In AC work the goal is to eliminate all leaks and the best way to verify that is to pressurize the system close to operating pressure and leave it overnight.
After a minute or two if the pressure on the tester kits gauge maintained that pressure then your cooling system checks out. Pressure Testing April 2013 Cool Concerns Ltd Cool Stuff from Cool Concerns.
Ok if the surge tank is low the dripping stopped and pressure still dropping there is likely a crack in the tank.
A cooling system pressure tester can be installed in place of the radiator cap. A cooling system pressure tester can be installed in place of the radiator cap. How to pressure test your radiator and find coolant leaks. I could clearly hear gurgling on the starboard side of the motor. The refrigerant in the tank should be on the same level as COLD when the engine is cold. Typically on a modern vehicle this pressure is between 13 16 psi. Let the vehicle sit with this pressure for 20 30 minutes. Then inspect the entire cooling system for any leaks and check the gauge on the pressure tester for a change in pressure. If in the morning the pressure hasnt budged youve succeeded.
Then inspect the entire cooling system for any leaks and check the gauge on the pressure tester for a change in pressure. I could clearly hear gurgling on the starboard side of the motor. Ok if the surge tank is low the dripping stopped and pressure still dropping there is likely a crack in the tank. Open the radiator cap when the engine is cold and you will see that the coolant level is touching the top of the caps flange.

Shop air or simply the pressure generated by the coolant system can be used to measure the pressure and check for leaks.
