[DML] Re: Leaking Antifreeze:CAUTION

["David Teitelbaum" <jtrealty@xxxxxxxxxxx>]

You are completely correct in saying the cooling system is NOT to be
overpressurized above 15 psi. To find leaks I usually pressurize in
steps. First I take it up to around 5 psi and look around. If it is
shooting out now from somewhere you don't need 15 psi to find it! I
let it sit for a couple of minutes and if things look good and then go
up to around 10 psi. Look around again and if you think it is OK, NOW
I go to 15 psi. This is done WITHOUT RUNNING THE MOTOR!!!! If you run
the motor the pressure will climb due to the heating and expansion of
the coolant. It is VERY EASY  to overpressurize the motor this way.
The radiator cap should also be tested to verify it will release
before going above 15 psi. You will probably blow the end tanks off
the radiator before you damage the motor but who wants to find out?
