plymouthasc Posted July 25, 2013 Report Share Posted July 25, 2013 Once again, I am posting for the Plymouth owner in Nevada who does not have Internet access. His 1941 Plymouth was overheating (boiling water out of the radiator). He put in a new radiator core, changed the water pump and hoses, flushed the block two times and replaced the water distribution tube. He said now when he climbs a hill in a 95 degree day the radiator does not boil over, but there is a boiling noise coming from the block. He said the water temperature gauge stays in about the middle off the dial. He can idle the car on a 90 degree day for a long period of time without any noticeable overheating. He is going to climb the hill again today or tomorrow and check the block with an infrared temperature gauge to see if there is a hot spot. Does he have an overheating problem? What might be the cause of the groaning/boiling noise in the block when the engine gets hot from a hill climb on a hot day? Thanks for your replies. Once again, I will forward your information to him by telephone. Quote Link to comment Share on other sites More sharing options...
55 Fargo Posted July 25, 2013 Report Share Posted July 25, 2013 Whats the problem here? Sounds like your Friend is not happy with success, all appears to be quite normal, as per your post. Could the fuel line be boiling and making this sound? At 95 f ambient temps, and pulling a hill, that isa huge load, building lots of heat, and if the engine is shut off right after, it will get hotter at first, until it cools down. I don't really see a problem here..... Quote Link to comment Share on other sites More sharing options...
Niel Hoback Posted July 25, 2013 Report Share Posted July 25, 2013 Air from the heater trapped in the system? Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted July 25, 2013 Report Share Posted July 25, 2013 This thing called thermal expansion. I hope the owner is aware that these vented cooling systems will seek there own fluid level. If after a long uphill drive if you stop the car and kill the engine the radiator will spit out any excess coolant. This is normal and the engine is not overheated when this happens. Once this happens the radiator coolent level should be correct. If the owner tops off the radiator after it spits the same thing will happen again.

plymouthasc Posted July 31, 2013 Author Report Share Posted July 31, 2013 The called and said everything is working okay. Thanks for your input. He thinks there may have been air in the block, but in any case, the car is not overheating and the noise is gone. Quote Link to comment Share on other sites More sharing options...
