In Reply to: Cooling System Flush and Cleaning posted by JerryU on January 09, 1998 at 04:16:57:
: Has anyone had any luck with some type of cooling system flushing chemicals (while the tractor is assembled). I have used several over the counter automotive types with little success. I can remember having a system cleaned quite a number of years ago when they "acid cleaned' it. I know there are acid products that are used in steam boilers. Would anything like this work. Or is all this an exercise in futility?
: My intent is to try to remove as much of the 55 years of sediment from my tractor.
: Any suggestions are appreciated.

Jerry, like the others, I would not recommend very harsh cleaners primarily because most Allis Engines have wet sleeves. The acid would break down the o rings around the cylinder sleeves. In the old days, we just put a hose to the engine water intake and let it run out of the engine onto the ground. My granddad did this in the vegetable garden so that the run off water was put to good use. You did not say which engine you have, but some have freeze plugs that can be taken out and you can get a lot of rust out from these holes. I know you don't want to open the engine, but this is pretty easy to do. Another tip is to fasten a hose to the block drain and push water through that way. If you do any of these, do it in the summer when you can run a while without antifreeze. You will have to change water quite a few times after disturbing old sediment.
