RE: {Chrysler 300} Lower radiator hose spring?

[rdr_inc <rdr_inc@xxxxxxxxxx>]

Flow goes into lower hose from rad, so it potentially can and will collapse from water pump suction at higher rpms and when hot and soft. The steel coil in lower hoses prevents such collapsing.

 So, yes, if new lower hose contains no coil, transfer the coil from the old lower hose. Since the upper hose is the return, it'll be fine.

Stay Cool,

Subject: {Chrysler 300} Lower radiator hose spring?

Folks

Just got both upper and lower hoses from Napa and the lower hose (Part #745) doesn’t have the inner spring . I haven’t removed the old one yet to see if the spring can be moved over to the new one but am wondering if that’s even necessary. In looking at online chatter, seems that the spring in the lower hose is supposed to keep the lower hose from collapsing during acceleration or under other unique circumstances?

Thoughts?

Keith
