While it's on my mind........Thermosiphon


Recommended Posts

I had to change two freeze plugs in my Kubota today. 

 

 

Years ago, in another truck I had, I had the Efan wired live. When I shut the engine down, the fan would cycle through several times in about an 8 minute period. I never really understood what was happening until I got a diesel tractor. 

 

I'm posting this for those who have, or believe they have, heat soak, or for anyone else that want's be become creative with their Efan. 

 

Once you shut your engine down, the coolant continues to flow, your thermostat continues to open and close until siphoning no longer takes place. I'm guessing, somewhere between 150 and 160 degrees. 

 

 

Many tractors, machines, and other industrial equipment rely solely on thermsiphoning as a means of cooling. My Kubota, for example, does not have a water pump. 

 

 

Just something to think about for those who want to take advantage of what is naturally happening anyway. By the time you run into a 7-11, fill your Big Gulp and pay for it, your temp should be down around 130 degrees with a live Efan.
