I checked out the fittings and they were fine for the time being. Bypass hose fit great too, think the other was the original so it was quite a bit differentbecause it was will past it'* day. Replaced upper radiator hose but held off on the heater hoses because the end in the firewall didn't look real easy to get to.
I replaced thermostat housing and am waiting on silicone to set to pressure test again.
I pressure tested before and the bypass hose was definitely leaking. My current radiator cap days 15 psi, is that correct for this vehicle? Not sure if it'* original. For how fast the needle dropped on the tester I can't believe I had to add coolant as little as I did.
