I'am in the process of changing my antifeeze and can't find a constant force clamp to replace the one on the water pump hose. Local Dodge dealer could not identify clamp and said to use a screw type clamp. The article in TDR #35 says to use constant force clamp only. the number on the clamp is MU67, neither Dodge or NAPA is familiar with this number. Any help would be greatly appreciated. The vehicle is 2001 Ram 4x4 ISB engine.
