by nwguy Mon Apr 24, 2017 8:28 amI found a heater box for my 62 truck on ebay, and it's on its way to me know. The prior owner of my truck said mine leaked when he tried it. He put shut off valves in the water lines to it so he could isolate it. So I want to test the heater core of the new one when it arrives before doing the swap. What's the right way to test for leaks? I assume you want to pressurize it when testing. Is using garden hose pressure OK? My house has about 70 psi water pressure. Makes me wonder what typical water pressure is in auto heating systems.

Typical pressure is less than the rating on the radiator cap. Mine has sprung a leak, it's just weeping now a little bit. I'm going to have it re-cored.

My truck is in the shop now having new steering kingpin bushings installed, so I don't have access to the cap. From what I can see, caps' highest pressure ratings seem to be about 22 psi. So I guess my 70 psi house water pressure is not the thing to use.
