I'm finding that I need to add about a pint of water every time I go out for a half hour ride in my 16 touring.

It has a new radiator and freshly rebuilt engine.

I don't think I'm over filling it, and I don't see any water leaks.

Suppose you don't add the pint. Does it go any lower and whats the level it's at when you re-fill it. A pint's not a heck of a lot by the way.

You are wasting your time. Each radiator will reach it's own level and then stay there.(unless you have a leak) try letting it go for a couple times to see if it goes further.If not ,enjoy.

Ok. Thanks.

I have not tried to let it go lower, but will do so.

I use about a pint a year in my cars typically. Here in Central Texas it's typically above 90 degrees every day from April through October.

If you are using that much water something is wrong.

I look down the radiator neck when the car is cooled off (before starting for a drive). If I see my reflection looking back at me, all's good to go.

Being a little lazy, I tend to lean on the "thermo-barf" method of radiator-filling.

As I know it's possible to under-fill the radiator to the point where the thermo-siphon principle will not work, instead, I fill it right up to the top, knowing that the car has enough horse-sense to barf overboard the excess and bring the coolant in the radiator to the precisely correct operating level.



As my car happens to run cool, even in the summertime, I only perform the filling ritual every two or three months.

I used to fill the radiator to the top, but expansion would spill out a good puddle each time. Now after it marks its spot I'll leave it alone and it's fine. Water will expand about 2% to 3% for 100 degree rise. A Model T has maybe 12 quarts. 2.5% of that is about one cup. If you filled the radiator to the top, one cup will come out. One Cup of water will make a nice puddle. I have gotten used to seeing where the normal water level is and adjust if needed. Just keep an eye on it and you'll become an expert on your car's water level.

As long as the level is above the core when it's cold, you're good to go.
