Cooling System Pressure Test
 

I've got a coolant leak, and want to pressurize the system with a pressure tester. Does someone know the correct pressure to test this system?

Thanks.

I'd just go with 5psi last time, never had problem destroying any parts if you are testing for leaks. See how fast the pressure drops if any.

Actually when I did mine, the coolant was drained due to leak when I pressure test (it's easier to listen for hissing sound anyway).
