Just noticed something this evening. Friend of mine was looking in the engine bay as I revved the engine. He noticed that my radiator hose would collapse each time I gunned the engine a bit. Cause for alarm?
Isn't there a spring inside the hose? I thought there was. I will have to check mine and see if the hose is rigid. If yours isn't perhaps they forgot the spring. And if so, I'd say yes it needs to be fixed.
