Recently I replaced a raw water hose which had a steel spiral wound "spring" in the core of the water hose, which gave the hose "anti kinking properties" when bent around corners.
This hose however corroded at the ends and the hose started to leak at the ends.
I replaced it with this hose shown to the left. Good quality radiator hose without the wire. When I installed the hose, it took the radius I imposed on it just fine. However after some months of running the engine, I discovered the hose kinked like that shown to the left.
which an explanation of how to use can be found here).
The hose has been installed for a month now, and is both water tight and kink free. This will do until I can purchase the original type of hose which I will carry spare lenghs for future replacement
