2G heater core

[7gGalant]

Ive look everyehere. But im trying to weld an fitting on my heater core for winter purposed. Can anyone tell me what matrial is made out please?

Should be aluminium, although really thin. Why are you trying to weld to it instead of T-ing off one of two hoses that go to/from it?

The reason its a pain the ass to get back there, and when the hose are its usually even harder. If putting ss lines on the heater care . easy on easy off
