[Mgs] Radiator Pressure Testing

[Bert Palte]

Dear fellow listers,

I have a leak somewhere in the heater radiator 
or the heater valve of one of my other cars, a 1972 Sunbeam Sceptre.

Were it an MGB, I would, of course, order new parts and exchange them, [mandatory MG content] but for this car it is almost impossible to get new parts and I have to resort to used items that I have had laying around for many, many years... 

Fitting these under the dash, however, is a PITA so I would like to pressure test them before fitting.

Question: What pressure can I safely apply for radiator testing?
I have compressed air @ 6 bar (~70 psi) at my disposal 
but I'm afraid that that will blow the radiator apart.

Any recommendations anyone?
