Re: Remove heater hose fitting from Alum intake
Steel and aluminum always have these corrosion issues, causing thread corrosion to swell. If you can, maybe you can collaspe the fitting by tapping with a chisel on the outside of the body. If you have the solid bushing type, you could try to drill out the inside and try to collaspe the wall also.
Soaking it with PB Blaster or LPS will help also. It also helps to have the manifold off the motor. But do use caution with the manifold.
