Awesome, thanks! I'll look into it. I've had experience brazing but it's been 10 years. The thermostat housing is in good shape. Since I haven't replaced the hose between the cooler and the pump that means it's over 20-30 years old and needs to be replaced anyway.

Thanks for the help. I have a Packard Service Manual 51-54 but if you don't know some basic things it doesn't help.

Thanks! I have replaced the hose going to the radiator but not towards the pump, I'll replace it and the clamps. Can the transmission cooler be rebuilt?

Help me with identification; the water pump has the fan bolted to it; but there is a device between the lower radiator hose and the water pump, with two lines going back past the engine towards the transmission. What is this? It seems to be leaking. Please see attached picture.

Regarding the cooling system, I replaced the hoses and had a professional clean the radiator, and he said it was in good shape. I replaced the thermostat. What else can I do? I would like to rebuild/replace the water pump. ideas?

Yes, yes I did. Got it from my father's estate when he died 4 years ago. I'm not much of a mechanic but I can pull parts off and replace them. I've changed the tires, exhaust, plugs, wires, had the radiator rebuilt, put all new fuel line, added an electric fuel pump, and an LED brake light to the rear window. I need to redo the brakes (again) and figure out why the engine is still overheating.

Thanks - I'll investigate the regulator as well as the generator. What am I looking for? I imagine it's a square/cube with electrical terminals coming from it and several wires.

I included a picture; there's something that may be the regulator in the top on the firewall above the steering column. Ideas?

Thanks! Did you ever figure out the cause? I think I may be drawing too many amps; I added a 6VDC fan to the front of my radiator. So even if I do get the generator fixed, the problem may not go away...ideas?

I've replaced the brushes in my generator, but it still is only putting out three-quarters of one volt. Would this polarization trick help? I noticed the solder from the armature is melted.
