Stallion Radiator Cap Part Number?

[rocket1lf]

Does anyone know what part number the radiator cap is? I know it is a 16lb cap, but it seems smaller than one that goes on an auto radiator. I replaced the temperature switch, with the correct one, but now it seems like the radiator cap is leaking. It did start leaking when the Stallion overheated on my trip, but it seemed to seal OK on the way home. Now when the Stallion is running at the correct temperature, it's leaking. Pipe temperature by switch turns fan on at 195 and off at 185, so I figure that the water is 205 and 195 which is what the original switch was supposed to run at. Thx Rick

After calling every parts place in town, I finally found the cap on Summit Racing's site. Here is the cap that is on our Stallions, at least it looks exactly the same with the same markings. It's an Expansion Tank Mini Pressure Cap 16LB. Canton Racing Products 81-016SM. Rick
