Radiator Filler Neck Replacement

[dmaxweb]

The filler neck on my '30 original radiator is damaged and needs to be replaced. Since the originals are crimped on and soldered, how is that done?

I would find an old school radiator shop in your area...if that is all possible, most radiator shops now just replace them, they have no idea how to fix them...what is this World coming to?
Lucky for me there is an old radiator shop that's been in business for over 60 years that's only about 25 miles away...your experience may differ
Or...you could try repairing yourself, do you know anything about soldering? (you'll want an air compressor handy)

Snyders has new necks to solder in. See https://www.snydersantiqueauto.com/4b056e35eacdd3e84835ff94d5599ddc/product.htm?pid=984014&cat=41737
Trick is to have everything really clean, use a lead-tin solder, and a good flux. A torch works better than an iron but be careful not to get it too hot.

A helper at hand, with gloves on may be a good idea too.

The problem is getting the existing neck out. The original necks on original radiators were crimped to the tank prior to soldering.

A good radiator shop should be able to handle that too. But, that winds up being on the clock and labor is not cheap.
