I hoping someone out there can help me. I'm having a problem water running out the overflow tube when filling the radiator on my 31 CCPU.My first thought was that I was pouring water/coolant into the overflow tube as I was filling the radiator. I have taped over the overflow tube just under the radiator cap to insure no water/coolant enters the tube but I'm still getting water out of the overflow tube at the bottom of the radiator. I saw one thread where there was a hole in the overflow tube in the overflow tube visible at the radiator cap. Anyone have any suggestions? I'm think of pressurizing the overflow tube. Any suggestions would be appreciated.
