Sometimes you eat the bear and sometimes he eats you.

My afternoon started with replacing the tank heater on my 1206 IH.

1. The bear got me. The drain valve on the block was plugged and I got a face full of antifreeze. It was about +2F and I have to work outside.

2. The welsh plug came out east and the heater installed in far less time than I thought it would take, poor bear.

3. While the block was drained it was time to hook out the heater hoses for the cab. That too went very well. The bears getting smaller.

4. Can't get heat in the cab. I've never done this before so I'm guessing that one has to bleed the system to get hot antifreeze to the heater core. Score one for the bear.

It a 1206 IH diesel with a year a round cab on it.

Buy you one of those Vacuum Coolant Fill systems. You attach it to the radiator inlet, apply air pressure to it, as the air passes thru this tool it draws a vacuum on the cooling system. It will collapse the hoses which is okay. After you get almost a perfect vacuum. You shut off the compressed air and see if the system holds a vacuum. If so you turn another valve on the tool and it will let coolant be sucked back into the cooling system. It works slick. It eliminates any air pockets in the cooling/heating system. Kind of like filling an AC unit on vehicles.
 
Cab heaters usually have a shutoff valve in the system so you can stop flow in the summer months.
 
Thanks John, I've sued those just in regular car work, never even thought of it for this.

Jms, the valve is open.
