Make sure your radiator cap is good and you might want to replace your current water/anti-freeze. | | | | | Joined: Jan 2002 Posts: 2,254 'Bolter | | 'Bolter Joined: Jan 2002 Posts: 2,254 | I agree. 1948 was a fantastic year for a truck

I like to flush with the engine running. I open the lower valve and put the garden hose in the top. Usually, the water goes from nasty color to clear. If it is real bad I will go with a radiator cleaner from the local FLAPS. Drain and flush, then fill with either pure coolant or a 50/50 coolant mixture.
Best of luck

Good Luck!
