Have a 1973 Dart Swinger 318 Auto no air. Have a 195 thermostat. Would it run any cooler with a 180 thermostat?
Thanks.If your radiator is in good shape, then yes, it should run about 15 degrees cooler. In a properly working cooling system, the thermostat setting can be thought of as the "low limit"
Beg to differ. Put a 180 thermostat in on the road running 10-15 degrees cooler in traffic running 10 degrees cooler. Anyway it does run cooler.Define "run any cooler"? If it is running 230° in heavy traffic on a hot day it'll still run 230° in heavy traffic on a hot day, no matter what thermostat is in it. A thermostat can't make an engine get less hot. All it can do is limit how cold it can run.
Thanks it did help had the radiator recored it is only a 19” radiator wish I would have went to a 22”. Oh well hindsight.if your cooling system is all in good shape,them it will run cooler.but if,say your radiator is plugged a little and your running a little warm now,putting a lower temp stat will not help
Sounds O.K. to me. You are not fighting an overheating problem. Because your cooling system has the ability to run at less than 190-195, it works. Like I said, the thermostat limits how "cold" it can run.Beg to differ. Put a 180 thermostat in on the road running 10-15 degrees cooler in traffic running 10 degrees cooler. Anyway it does run cooler.
