Is the anti-collapse spring necessary? The old hose I took off didn't have one and the new hose I bought didn't have one. I hate to put it all together and then read on here next week how necessary it is and then I won't be able to sleep at night knowing I didn't go find one and install it! Thanks for input! Ron

It use to be ALL new lower hoses came with a spring already in them. Not any more  Without it the pump at high rpm's can suck the hose closed. Not the thing that you would want  If you can find one put it in. I try to save the old ones when ever I can

You can make one by wrapping a peice of wire around a broom stick handle.

Age old debate...
You can use them if you want but if the cooling system is flowing properly it shouldn't collapse. My Coronet had the problem and the radiator core was almost totally blocked. When I replaced the core the new lower hose had no spring and was installed as is. I have had no issues with it sense.

Would coat hanger wire work?
What about "rusting" of the spring?

go to a welding shop & ask them for a single piece of stainless welding rod & as said bend it around a broomstick & install it. Turn the ends in toward the middle so there's no chance if it puncturing the wall. A guy said that they are actually used by the factory only to keep hoses from sucking closed when they vacuum fill the cooling systems & others have stated that worn out hoses can suck partly closed in actual use so make/install one & you can move on to other issues & not have to give it a seconds thought.

I got flamed last time I posted on this subject 
but what RapidRobert said,and for those reasons 
some times a hose is just soft and weak,and "IS" the only problem with the cooling system 
Why'd you get "flamed"?

Yes it would, it just won't last as long. I bet it'll last 5 years with the proper anti freeze mixture.

I'm trying to figure out how the hose could get sucked closed. I think that the cooling system is a closed system with no air in it. Full of liquid coolant. If everything is full at idle engine speed--block, heads, pump, hoses, etc.--which comprise the total volume of the system, and we diminish the volume of the system by collapsing a hose, where does the the liquid coolant go? Does it expand another hose? Liquids, including water and ethylene glycol, essentially are incompressible fluids aren't they? I'm referring to a system with a coolant reservoir and two-way vented filler cap.

I'm totally agreeing with your logic - only theory I can come up with is its just one of them things that happens; like the SF bridge twisting in high winds or a straw through a tree in a tornado - it musta happened somehow for all them thar springs to go into lower radiator hoses.

I have had this happen. I went to the local Murray's and found a universal hose with a spring in it that matched, then I took it out and put it in my Mopar hose.
Best theory I had, some of the repro hoses are pretty soft and they collapse as they heat up, from the internal forces.

It's really no different than the light in your fridge, you have to take a ride under the hood at WOT to truely know the answer....Barring that...It's all theory and I challenge you to show me...Video would be nice. P.S. I run a spring 'cuz I ain't gonna take that ride
