Were they just deemed unnecessary, or are they just saving money? If my old hose had one I would have transferred it.

I think there's a possibility the hose may have collapsed a couple times in my Power Wagon while in traffic on hot day. Gauge shot up. Everything new including hoses, max cooling rad, milodon thermostat, milodon water pump, block flushed, new freeze plugs, and coolant distilled water mix. I couldn't get out and look at hose in traffic. I guess gauge could be faulty but temps went right back down when traffic started moving again.

Why did they remove springs?

Stronger materials and yes saving a few pennies.

Pure money savings. Just like when you buy a brake hose they no longer come with new copper washers.

I can tell you the only reason they put them there was for initial fill purposes only. It was NOT to keep the hose from collapsing in use.

They probably quit putting them in because they started using a new fill method.

Electric gauges? I'm thinking just normal temp bump from less air/water flow at idle.

I always transfer my spring when putting in a new hose. I don't care what they say, it IS needed! I helped fix a factory Hemi Dart that was overheating. I stood above his radiator as he revved it up and watched the hose collapse shut! eek

iagree On my Challenger, I could watch my temp gauge climb on the highway. I put a lower spring in, and no problems since then.

So can one buy a replacement spring to put in a lower hose, if you wanted one?

I ordered from CJ Pony Parts. Lower radiator hose spring stainless steel small block 1965-73. It was $8.99

I went to the local auto parts stores and bought a universal corrugated hose with a spring in it for 10.00. Pulled it and installed in my hose.

It is my understanding that cooling issues in the conditions you describe is a cooling system issue, and that the high temps on the highway are related to the lower hose collapsing.

the 15 psi inside a proper cooling system should easily keep the hose from collapsing.


Take care,

(sarcastic statement) Is this something they look for when judging a vehicle at the concours level?

Its called the Charmin Test. It is in the Judging Guide, look it up.

if your lower hose is collapsing your problem is not lack of a spring. It is something else.

Why does it collapse and what causes the condition needed? It's not lack of a spring.

I'm pretty sure that's not how it works wink There is only 15 psi in the entire system when the temperature is quite high. At 180 degrees there is a few psi on the output side of the water pump (that's what moves the coolant through the radiator, heads, block...) but the inlet side can very well be under suction. A lower hose collapses because it's being sucked in, which by definition means there is negative pressure inside it. work

Now if there's a restriction in a clogged-up radiator, it's even more likely that the water pump will have vacuum at its inlet (the lower hose)...

If the no spring is causing it to overheat at idle/low speed I would think it would be worse at high speed on the highway (with higher suction on the hose if that is linear) & he says it is OK then.
