Heat Exchanger Cleaning and Testing at Radiator shop

[zboss]

Folks,

After going through the really need to do list (such as new seacocks - egads) I am looking to do soem stuff myself. It looks like I am probably going to have to clean the heat exchanger. But.. I can't pressure test it. What pressure are the exchangers supposed to be checked at?

If I go to a radiator shop do they just use a standard pressure?

Thanks,

Z

I'd use a garden hose at 50psi. Why would you expect less? If the end cap gaskets leaked, so what.
