Something like :The inside diameter of the rad hose is 1 1/8 inches so I need a barbed T from 1 1/8 rad hose to 5/8 inch for the heater hose.
Any idea on where I might get it?
The lower hose is the suction side of the engine to the radiator. I suggest that if you want to make your life easy, then do what I did in 2004, and remove the bypass hose, and purchase 2 right angle hoses of the correct diameter, and install that on one side of where the bypass hose was located. Using the other right angle hose, put that on the other side of where the bypass hose went. Then purchase a plastic adapter at the auto parts store that will bump the smaller hose up to the 3/4" heater hose. The engine will never know what you did, and you will have more than enough hot water flowing through the heater core. In the morning, I will get a picture of my BX22 with the heater hoses installed as I have described.The fitting is for the coolant leaving the radiator through the lower hose, I can tie in directly to the engine with the other.
Yes, I didn't explain it clearly enough, but as I said, it is the suction side. It actually goes from the radiator to the water pump. Some of our older members might remember when the lower hose had a metal spring in them, to keep them from collapsing. Today, the lower hoses are more reinforced, and the spring is no longer needed.Doesn't the lower hose contain coolant running from the rad to the engine?
I had a Kubota deluxe cab installed, but I told them that I would do the heater lines myself. Saved myself 3 hours of labor, although they did install the factory heater instead of my receiving it in the box and installing it myself. I wanted to install a block heater, so I knew that I would be draining the block, and installing the heater lines at the same time. So far, the tractor hasn't gotten hot enough for the heater to work. My BX22 would get hot in less than 10 minutes. I think that my thermostat might be stuck open, but I hate the thought of draining it down again, just to check it. I will know better once I start working the tractor later this spring.nice pix, which 'kit' did you use for the bx23s ? pretty sure it'll get cold again next winter.....brrrrr
BX'r, your third pic clearly shows the short "bypass hose" on the thermostat/pump housing. When I added a heater to my home made cab, that bypass hose was removed and the heater hoses replaced the bypass hose connections. I ran the same size hose all the way up to the cab and then upsized with barb fittings to the 5/8" hose into the heater itself. Much easier to run the small size hose from the pump to the heater and there was still plenty of circulation for the heater to function properly.This is my thermostat housing.
I think I can use the water pump and thermostat connections as you did DR.
