My truck started as a 46 1/2T truck. The radiator appeared to have a non-pressurized cap. Don't know if that was correct. I now have a 1955 235 engine installed and have gone to a new after market radiator (supposedly designed for the 46 truck) and came with a pressurized cap. What is correct - what do I need - do I have a problem?
