Lower radiator hose collapse

Posted by jwblazek On 2019/12/21 10:39:55

FINALLY finished installing my freshly rebuilt engine in the car, everything hooked up and it started right up, what a great feeling and sound, NO SOUND , a quiet engine!

The old radiator hoses were replaced with fresh new ones. I did notice the old lower one had a spring inside it to prevent it from collapsing but the replacement does not.

At anything above a fast idle or even momentarily revving the engine, I see the lower radiator hose collapse upon itself.

I understand the spring is supposed to prevent this, but want to be certain something else isn't amiss. Fresh water pump and radiator was cored at a reputable shop, is it possible there is something wrong with the radiator before I hang the fenders and nose on?

If it needs a spring, where can I find one? Have scoured the web for one without success.

Thanks in advance !
