Radiator is back from the shop. Manager tested it and said leak was coming from the bad petcock. Why, then, was water dripping from the opposite side on to the front axle, etc? Could water have travel across the bottom of the radiator?
Yes. Water has a way of migrating from itís origin to other locations. That is why it is so hard to find where a roof leak actually is.
Thanks, Steve. Was pretty amazed when he told me. Glad I got all the cleaning, painting, etc. done anyway. Better now than in February. Coolant was eating all the painted services. When reinstalled, will fill with just water first.
Water is like electricity: it takes the path of least resistance
RE bad petcock
It would drip off the casting before it would travel along the bottom, unless it sits at a real steep angle to the passenger side and downhill. Maybe then? Sitting flat, the casting for the outlet would be the lowest spot.
Mark, I see your point. The radiator guy sounded pretty confident. He performed all the obligatory tests. It was strange where and how the coolant was leaking - on the far left-hand side of the radiator, when the petcock is on the right (facing the radiator). Will see this weekend when I remount it. One thing for sure - it will be just water first and keep my fingers crossed!
Hopefully when he tested it he didn't use over 2 lbs if any air pressure.
Why not fill it before you put it in the car? It might be easier to find the leak for sure that way.
Will do, Steve. Thought the same thing, too.
Water with antifreeze will weep from holes that water alone won't.
Define "bad petcock". Right off one would think that means the valve is unseated in the body - maybe the radiator guy meant the pipe threads on the cock were bad and didn't seal in the radiator tank ?
Rich and David, both comments noted. The petcock is shot. No biggie. Had ordered a replacement with new hoses. The radiator is on my patio with water in it. No coolant. Will inspect for leaks. A very sunny, hot day in Pa.
May just opt for a new radiator.
Do not want to mess around with it in the dead of winter under a carport. Will decide this week pending the results of the leak test.
Question: With the T running, once the radiator is installed, would that prompt it to leak again?
Kind of a moot point now. Tested radiator. Still is leaking. Will check it out tomorrow for something obvious. Otherwise, time to start looking for a new one. May give the shop one more crack. We'll see.
I assume this is about your 1920. If the radiator fails to do its job, leaking or not, after you have cleaned the system, it's time for a new one. With a brass era radiator that has good original tanks I would have it recored. For a black era car like yours, I'd get a new one from Gery Bergbower.
Thanks, Steve. Sure looking that way.
Does anyone have Gery Bergbower's contact info for new radiators? Thanks.
