David,

Just looking at the photos it didn't look that bad to me. (Ok, I'm old and wear glasses...)

Is the car over heating or is there some other reason you want to remove more of the rust residue from inside the water jackets?

And if the car is over heating -- is it really over heating or is it just getting hot and water is running out of the radiator over flow pipe because you may be adding too much liquid to the radiator?

I’ve used the typical “Prestone Radiator Flush” in several cars and been fine with that. Just following the directions. For that you want the water hoses back on the engine etc. Although since you already have them off have you tried putting the water hose in the top outlet, turning on the water and seeing how much if any rust pours out the side? There is a video at: https://www.youtube.com/watch?v=i36pDzhFkBQ as well as the instructions on the bottle. On Ts I normally start the car and get it hot. Turn off the car and drain the coolant (catch it if anti-freeze – keep away from kids and animals). Replace with regular water and repeat the process several times until when I drain it the water is clear. Then I do it one more time with the Radiator Flush and after that several more times with plain water again until the water drains out clear. Then I drain it and add the proper mix of coolant.

Some more sophisticated suggestions are found at:

In general – many new Model T owners are concerned that their T has fluid coming out of the overflow pipe when they run the engine for a while. But many times they are filing the radiator up to the top when it is cold and if they do that, then when the engine warms up the coolant will usually flow out of the radiator over flow. (I don’t know about some of the fancy coolants like Evans etc. – do they expand and flow our or not? ) But regular water or regular water with antifreeze will expand and go out the overflow pipe. That will happen with everything clean and rust free also. The solution is to only fill it up part way. How high? I usually just fill it two inches from the top and then I don’t add any more if any goes out the over flow pipe. It will seek the proper level and if I don’t add any more to the radiator – it is now happy. (Ok – if I park down hill on a step hill with a hot engine some more will probably come out – but in general – its ok at that point.

You have a nice looking T. If you have already sent me information on your body number -- thank you. If not -- please take a look at the posting “Home for the Holidays” at: http://www.mtfca.com/discus/messages/29/40322.html and let me know if your car has a body number or body manufacture letter and if so what the letter and/or number is.

Good luck and let us know if you need additional advice or not.

Respectfully submitted,
