Crack around water radiator nozzle

[JerzyGeorge]

Bottom nozzle of my Savannah water radiator developed minor leak and on closer inspection I found hairline fracture where it was welded onto body of the radiator.

 

Is the installation of the radiator ( hung on rubber hoses only ) a contributing factor?

 

Any ideas on radiator installations.

 

On other aircrafts I have seen it bolted on brackets , not relying on rubber hoses only.

 

Thanks for any advice

Yeah I had the same thing couple years ago.

 

Radiator place welded the spouts up and been fine since.

Thanks for the information, I did the same , took it to radiators repair shop , have not tested in flight yet, but there is leak when cold.

 

Still not sure about radiator hung by the rubber hoses only . Any other radiators I know of have been solidly mounted, example oil radiator in the same aircraft. Surely vibration must cause material fatigue.

correction should be NO leak

hoses under pressure are a shock absorber.
