Re: Cold weather driving with or without thermostat?
The two 1/4 inch diameter, (r=0.125) holes have a total area of .098 SQ IN
The one 0.43 inch diameter hose (r=0.215) has an area of 0.145 SQ IN So the 0.43 hose has about a 50% larger opening than the two 1/4 inch openings https://www.bing.com/search?q=area+o...24c4f823d08781

Re: Cold weather driving with or without thermostat?
The commercial 'stat housing has bypass holes machined into it. In my prior arrangements, I supplemented with two 1/8" drilled holes. Also, have heater hose for bypass (without metering valve, but with shutoff valve for summer use). Years ago, used cardboard when A was my daily driver: what a PITA. I was sooo happy to discover thermostats!
I think the "thermal shock" business is one of those things that sounds good if you say it fast, but otherwise is a bunch of hooey. Last edited by steve s; 11-28-2018 at 12:33 PM. |

Re: Cold weather driving with or without thermostat?
For the weather in my area, I do what was done originally. A cut a piece of thin plywood or cardboard, about 1/3 rd of the radiator for the limited driving I do! I do understand we are all different and those that add a thermostat, is fine. Just not for me!
