Disconnecting Oil Cooler Lines

Any suggestions on removing the oil cooler lines?

I'm replacing the fender mounted cooler with a much larger front valance mounted one but, the factory fittings are frozen. I have used AeroKroil and other penetrants but the fittings are still stuck.

Anyone has words of wisdom?

Hi,
I did it by using the "flame thrower", a small gas-fed flame, heating up the connections. They will loosen quickly. I know it sound pretty rough, but it is not.

Thanks Tom, Ill try that and get back here with the results.

Thanks again for the help and quick response time.
