Default radiator issues

Has anyone had any problems with larger radiators leaking?
I'm on radiator no. 4 in 4 years... They always leak in the same spot, too. At the location where the coolant tubes are soldered into the tank on the passenger side.
I bought the car with a fluidyne, put a mishimoto in it when it went bad, and am on mishimoto no. 3. They have a lifetime warranty so no problem replacing it, it's just getting old.

Any ideas?

Electrolysis in the system. add a ground strap or two to the cooing system, one at the heater core, one on the radiator.

you might wanna check your heater core condition if you have a spare weekend. chances are good, its next.

hmm i didn't think of that. thanks! i'll do that today... i replaced the heater core two years ago with an original ford one. i hope it's still ok.

thanks for the quick response! i guess i'll find out if that's what it was in about a year. lol

Hope you are not using the 19 pound cap it comes with.
