Bottom radiator hose question

[Gus cuda]

Hello all, my car has been pushing coolant out the overflow. It doesnt matter how full it is, i tried replacing the cap with a 16 psi stant, didnt stop it. I noticed my bottom hose does not have the spring in it, do you think it is collapsing and causing this problem? If so, where could i find the hose with the spring? Temp guage never reads over half, but i know it could be wrong. I have checked all over it with a temp gun and at the water pump housing the highest temp i have seen is 185, engine is stock with a 26 inch radiator that is clean. I also have a 160 thermostat in it. Any help is appreciated, tired of leaving my mark everywhere i go. Thx Gus

How full are you filling it?  I have mine about an inch down.  I still get a little dribble once in awhile.  If I wasn't concerned about looking stock, I would install an overflow tank.

may be over-filling

try a level 2 or 3 inches below top of radiator,
while keeping an eye on temps.

I suspect your overfilling. I have a 180 stat and my mechanical gauge shows 190. The temp gauge on the dash shows not quite 1/2 way. Every time I've filled mine, it always pukes some out until its just barely above the fins in the radiator.

   Mine    when I shut it off after I've driven it a while on a hot day.  I would be more worried if you are leaking coolant while driving. 

Make sure your fan is up inside your shroud too, this really helps keep things cooler.

1st - there is a plate under the rad cap inside the tank , that is the max fill line .
2nd - are you getting constant bubbles with the cap off if so you could have compression entering the cooling system

[burdar]

That's what I though too but he said the temp has never gone up. I would think there would be overheating issues if there was compression in the cooling system.

Ok folks ill try to address your suggestions. First it doesnt seem to matter where the coolant level is, i have let it drop down to the fins and its still pushing it out. When i say pushing it out, im talking a "running puddle". If it were a few drips i wouldnt worry. The car doesnt seem to be overheating, no steam, or burbling. Car runs fine, and there is no coolant getting into the oil or vice/versa. As far as bubbles while the cap is off, i will check that in the morning. Thx to all of you!

maybe fill neck on radiator is not level, or damaged, and not allowing
cap to seal properly.

Are you 100% sure that it is coming from the overflow hose. There could be a leak in the radiator itself the causes the flow to "trail" off the overflow (side of the hose) without physically travelling through the overflow itself...

[Gus cuda]

Update: i checked for air bubbles with the cap off. Didnt see any, left it run until the coolant was at a nice flow. As for a radiator leak, i will check it next time i drive it. Im pretty sure it is coming out the tube though. Also the "running puddle" im speaking of; i mean it puddles on the ground and runs, not like its a constant "run" out of the overflow. So it sounds like nobody is worried about my hose not having the spring? I was thinkin maybe its collapsing and not allowing the coolant to settle back down correctly. But hey, im no expert, just learning my way around this thing!

[ammo]

If you not sure if its the overflow hose or the radiator , I would just try lengthening the overflow hose away from the radiator a foot or two and see if you leak moves.   

[cudabob496]

I have a quart size overflow bottle, and I keep the level in the alum
radiator about 3 to 4 inches below cap.  In the summer, I have to empty
the overflow bottle, and poor the coolant back into the radiator, about
once every 3 or 4 weeks. I have a 16 PSI cap.  Maybe it "relieves itself"
every once in a while. Especially when I am getting on it, and its
above 90 outside. Coolant system coolant expansion is normal. I change my cap regularly too.
I stopped using the kind of rad cap that have the red relief lever on the top.

Maybe your temp gauge is bad, and you are having an overheating condition.
So, maybe start thinking about all the things that could make a car overheat?

plugged radiator, timing off, stuck thermostat, fan 1/2 inch from Rad, and fan halfway in shroud, etc etc

too high a coolant concentration can hurt cooling.

[Gus cuda]

I'm pretty sure the rad is not clogged, upon inspection I see that my fan is about halfway into the stock shroud. Is that correct? If not what can I do to move it in closer? Haven't checked the timing, car seems to be running as it should. As for coolant, I keep it 50/50. As for a stuck stat, it is only 2 yrs old but I guess it could be bad already. Guess I have some trouble shooting to do, also maybe install an overflow bottle. I do appreciate all the help in what direction to go in from here. ,
