i don't have one in mine but then i have an aluminum radiator, so i have 2 different size ends. i took my hose to checkers and found one that had the same shape in it, then cut the extra length off each end. seems to work just fine.
yes. the hose walls need the support to stop them from collapsing when they get real hot . Some hoses have a different construction and r stronger. If it came with a spring then use it It wont hinder the flow of water.
rad hose if the new one came with a spring then use it or go back to your supplier and ask him why the springs there. never assume when it comes to auto's:bananaman
The lower hose is on the suction side of the water pump. When the hose gets hot and softens the suction can colapse the hose, then you'll overheat.
Today I noticed my old rad hose has a spring inside… At this point there has been no replacement of anything having to do with the cooling system… In the process of draining the rad… I BROKE OFF THE WING connected to the drain screw for the rad… so now I have to take back the hose and find one with a spring in it…and find a drain plug…. My main question is…. What does everybody use for radiator hoses? Is rubber the only thing out there for a rad hose?
I am still using a rubber conventional radiator hoses, and yes my lower one has a spring inside. You stated you broke the thumb tabs on your petcock, you can still open and close it with a pair of pliers, just dont tighten it too much or you might never get it to open again without tearing it up.

This man knows what he is talking about! Cost me $2500 to learn that lesson, bad thing is, if car does overheat by bottom radiator hose sucking together........ time you stop and get out to "look"..... it will have went back to it's original shape......will look OK.........will never put on another bottom hose without a "spring" in it!
I was thinking of replacing the “petcock” because I will be flushing the system anyway… I think some sort of pipe fitting would work.
I found my rad hose with the spring in it…This rad hose is quite inferior to the one in the photograph… I think ill try stuffing the old spring into the new hose… Thanks for all the help :bananaman
the only exception......if you use a flex hose......they have a wire coiled around inside the rubber.........doesn't need the spring inside the hose......
hosed It also depends on the hose construction. Look at the hose without the spring. More fibers in it for support. Spring is old tech that still works thou. Problem was the older radiator caps didn't vent properly when the engine cooled down. That's why the return container is used now. When the engine cooled the hose was sucked in.
