Flushing the radiator
Is there any way of doing a "back flush" on a 617?
I know all about the citric acid flush, but wanted to know if I could back flush the system first to get the majority of the crap out. I did a search and came up empty on back flushing. Which hose would I cut into for the tee? I would imagine the one going into the head, but there doesn't seem to be enough room in the hose.

I takes about 10 minutes to remove the radiator from the car. Take it out, turn in upside down and flush away.
Removing the radiator also provides a great opportunity to clean/straighten the fins. |

That will only flush the radiator though, not the whole
system

Apparently, I misunderstood the title of the thread.

i would not install a plastic t in my hose. i've seen those things leak on several cars. if you run a cleaner in the system and flush it good, it will be fine. no need for a t. if you feel you need more, fill it with water drive it for a few days and flush it again.

I connected series of 1/4 inch pipes to the block drain, then connected a piece of garden hose to the nipple.
I connected the hose to the piece of hose and flushed away... I used a 2 inch nipple, a 90 degree elbow, a 4 inch nipple, a 1/4 inch ball valve and another piece of pipe, which I connected the hose to with a hose clamp to make it secure. You can run the water into the system, then close the valve to let it circulate for a while before removing the garden hose and letting it drain.

ROTFLMAO !
I was going to comment regarding the thread title, but that is even better. If you wish to perform a "Cooling System Flush" and do not want to isntall the "prestone flush tee", simply disconnect a hose, install a barb adapted to a female garden hose fitting. Connect the garden hose and administer water as needed. A section of hose with the appropriate ID can attach to the fitting that now has no hose attached. This length of hose could be directed to a bucket or barrel to capture coolant/contaminants that perhaps (hopefully) you dont wish to wash out to the ground. for the summer months I do recommend running the system with straight water for a period of time (day, week, what ever), flush again, then refill with fresh coolant and test specific gravity. While on the subject of "flushing," dont forget your brake system. This should be flushed every one to two years.
