Radiator Heights

[Tom Stephens]

I'm trying to find the height dimension from the top of the crank handle (where it goes into the motor in front) to the top of the radiator shell (not including the filler neck) for the 1915-16, 1917-23, and 1924-25 radiators.

I would appreciate it if those who have those year radiators could give me some actual measurements off of your cars.

Thanks!

From the top of the crank handle to the top of the shell on my 23 is 23½". For 24 and later you can add about an inch to that. I have the radiator off my 15, so I can't help on that one.

What are you trying to figure out? 1917-23 23-5/8" and 1924-25 25-1/4" These are approx. As you can see there is different measurements for different cars.

[Tom Stephens]

Thanks Steve!

Mark, I am trying to figure out how much lower the '15-'16 radiators are than the '17-'25s. You both have done well on those last years, now I hope someone can chime in with the '15-'16s.

In all the threads I found on radiator measurements, where to measure from at the bottom of the radiators caused many differences. I thought if I can use the fixed top of the crank handle (where it goes into the motor in front), I would get less variation from car to car.

I've got 21 3/8th in my 1915.

[Tom Stephens]

Chris, is yours a black (later style) or brass radiator?

Tom

[Mark Gregush]

15 would be brass.

[Tom Stephens]

Mark,

Per Chris's avatar, he might have a '15 motor, but that speedster has a black radiator.

21+" sounds about right for a brass radiator. You will note the difference between the number I gave for the low black radiator(17-23) and that number. The 15 to about 18, the radiator sat on leather pads only under the mounting ears. Then from about 18 up there were springs in cups in the mounting ears. Depending the crush of the springs, the measurements can vary.
I would think a better measurement would be from the top of the frame rails up which would be a little more hard to get with the shell in place. Chris list both a 1915 and a speedster in his profile and the avatar shows the speedster from the rear.

My 15 is a brass radiator.

Thanks guys, EXCELLENT! I keep seeing '15 speedsters and they always look a lot lower than the black radiator ones. I had no idea that the brass radiators were THAT much lower. Positive proof.

I appreciate the info!

Chris, I sent you a PM.

Also having a dropped front axle lowers the front too. Many are setup that way when it comes to speedsters.

[Tom Stephens]

Mark,

Yes, what you said

Check your PMs too.
