I just picked up an 85 GT from the original owner with 95k miles. It's in real good shape, but needed maintenance bad. Among other things, i decided to change out the radiator hoses. On the lower hose, i noticed that the coil wound spring that sits in that hose on all 5.0 stangs was broken, and in pieces that literally fell out of the old hose when removed. Since i obviously cannot reuse it, is it bad to not put one back in? Would it adversly affect my car without it? Where can i get another one? Thanks.

Yes, the new hoses i used were the Goodyear Hi-Miler blue silicone ones, but there was no spring inside already.

I changed out the upper and lower radiator hoses late last year w/ Kragen ones. Their doing just fine also. The Mustang is also a daily driver that gets beat-up in the commute all day long. ![[Frown]](frown.gif) I don't know if there is a spring in it either. And I just put in a new radiator and stuff last month also while using the same hoses I swithched out last year.

The spring in the lower rad hose is to stop the hose from collapsing(sp)....On high RPM, sometimes you can watch your lower hose shrink as the waterpump suck through the hose...
Basically on the cheap rubber hoses, once they get satchurated(sp) with oil they get soft and actually can really restrict/stop coolant flow by collapsing when the engine accelerates hard...
I actually bought another hose with a nice spring inside and installed it in my last rad hose, just as a precaution....I figure it couldn't hurt...
Good luck...
