If you have not seen the actual leak, it's possible

the vacum valve is the source of the leak.

It happened to me.

Try Hill's Thunderbird Center they also supply Ford parts but I only have the Thunderbird phone number 1-800-562-1955 Always good service and the correct part at the price quoted not like some others that I have had bad experiences with. Or try Bird Haven at 1-866-302-3673 (FORD) Their Catalog # Y-12 is the most complete for '54 thru '56 FORD & MERCURY that I have ever seen with original part numbers and good pictures.

What?

I'm not a really big fan of Mac's because of occasional problems with delivery time, but if you decide to go with them use code JULSALE132 for 10% off through 7/17.

A radiator shop might be able to fix it but it may cost as much or more than Mac's...

Hi, 1957 ford fairlane heater core is leaking real bad when the heat is turned on. I assume that means I need a new one. Where would be the best place to buy a new one ? Thanks
