What is this radiator hose for?

[Jeff Lary]

I am going through the cooling system on my 1995 L2950 Glide Shift tractor. It is 27 years old and I figured it was about time to change the hoses out for new ones. I am not having any issues it runs and cools just fine as is. However if I do have any cooling issues it will surely be in the dead cold of winter a 1/2 mile back in my woodlot. So this is just Preventative Maintenace only.

At Messicks Tractor parts site the part number is 31351-18570. The hose is located on the lower right of the engine and goes in the lower right corner od the radiator. The name of the hose is " drain hose" I have a new one here along with top upper and lower hoses, Thermostat Coolant all ready to go does anyone know what this third hose does it is about a 1" od shape formed hose about 2' long maybe? Thanks Jeff

So what goes on the other end of the hose?

 

[Jeff Lary]

engine block and rad connects the two?

I just finished the cooling system service, that hose goes from the lower right radiator to a barb in the engine block under the fuel pump. When removed there was some coolant in it. I have no idea what it is for when you look it up it is called "Hose drain" anyway thanks for the response, I was hoping someone could explain why it is there. Thanks Jeff

Does it allow trapped coolant within the block to drain via the radiator so only one drain point?

 

[Jeff Lary]

You got me It is called drain hose maybe to drain the block? I changed it out now all three and a new thermostat ready to roll, I guess. I discovered this when trying to read the oil filter number the hose is formed to pass below the filter. I said, " hua small lower hose isn't it?" Then when i walked around to the left side of the tractor both upper and lower hoses are on that side. So yea I have no idea but she is new now ha ha.

That'll teach you not to scratch sleeping dogs and going around fixing things that ain't broke...

Yea I know but I got to thinking, geese 27 year-old radiator hose ..... better get these changed out. You know where you end up then. I know now that they are all in great shape so I sleep better ha ha.

Maybe if you post the question over at OTT you might find someone that knows the answer...Just a thought.

I'm about to do the same "Preventative Maint" on my 2000 Kubota L-3010. No probs yet but don't want any
Like you, I went to Messick's website and they show 3 hoses, one is a small (maybe 1" hose bottom Rad to eng block)
I called the Kubota dealer and they do have a listing for it. Does anyone know if it carries PRESSURE? If not, I won't bother changing it.
Thanks, you guys are the best
