flushing water distribution tube

[p24-1953]

does the water distribution tube become cloged w/ rust or what? i have water flowing through the block because the heater core gets warm, but i do run hot. i was planning on removing the "freeze" plugs and clean as much of the block as possible but was wondering what prevented you from removing the water pump and cleaning the dist tube out rather than fighting to replace it. would a reverse flush help break things up? or a small run with vinager to help loosen everything prior to removing the plugs.

I had this issue when I got my Windsor. I removed the tube and found that it was plugged with hard material at the end and was keeping water from flowing to the last 2 cylinders. When you pull your tube and clean or replace it you may find that is all you need to do.

If the tube is rotted away or plugged all the coolant will stream up the front of the engine. This will make the back of the engine run hot while the front runs cool. An electronic temp sensor will give you a good reading. Front and rear should be the same or within 20 degrees.
