  • Hot, need help on this ASAP

    Guys-
    Here is the scenario, drive my 53' 2R11 (Commander 6) to work, wait a min.. it 'smells' funny....hey! were getting warm! I shut it off. The LOWER HOSE TUBE IS COOL TO THE TOUCH! So I (cool it down) and swap thermostats. The one I put in ops ck good in a pan of water this am. Start, run breifly and the lower hose is still cool [}]... -no flow. Any inputs? Can't be a bad pump, unless the impeller blades are shot, No way. 8500 miles on rebuilt eng. Runs like a top otherwise. Can a 'bubble' cause this? How do I remedy trapped air? Reason I ask is the coolant was very eager to exit the bolt holes for the thermostat housing (gooseneck), and this was LONG (4 hrs!) after it had cooled. Clearly there was pressure behind it.
    inputs appreciated, dead in the water[xx(]

    Sorry to hear about the problem Dan. Yep, a bubble, or a pocket of air can shut down the flow. The "coolant was very eager to exit the bolt holes for the thermostat housing" because your block is full of coolant and that sounds normal. I would leave the thermostat out and try it again. That'll do a couple of things, first it will help to clear the air pocket if you have one, and second, if you service the radiator, (and has anyone ever told you that you have to leave about an inch of space from the radiator inlet to the level of coolant in the radiator?), you can actually see the coolant circulating. Over-servicing it, then using a high pressure radiator cap, (or a cap that's bad), will make it overheat too Dan. Keep us posted will ya?

        Here's what I can add as to the cool lower hose. I've actualy SEEN this with my own eyes. If the lower hose develops an obstruction, the hot water stays at the top of the radiator. Since there's no circulation route, the heated water can't much get past the thermostat. Nor is the hot water gonna try and go backwards to the radiator.
        What I've seen is the lower rad hoses do two different things. One, the internal spring (assuming there was one to start with) rusts away and lets the pull of the water pump suck it shut. I"ve seen this phenomenon happen with my own eyes. Sometimes it only does it at increased RPMs - so your car gets hot, you get out and have a look-see under the hood and all seems OK - unless you razz the engine a bit and just happen to be looking at the lower hose as it collapses!
        Another version of this is where only the inner layers of the lower hose collapse. Then even revving the engine gives no clue because the exterior of the hose appears OK.[}]
        Also, I've seen the impellor wheel of the water pump come loose from the end of the shaft! No noise to indicate anything's wrong - just not moving the water at all![xx(]

        Miscreant at large.
        No deceptive flags to prove I'm patriotic - no biblical BS to impress - just ME and Studebakers - as it should be.

          That's a sure sign that it's not circulating. That radiator was cleaned, correct? If that hasn't been done, that's the [u]First</u> thing I'd do, get it rodded out and cleaned. BTW, you do know that, to reduce mineral buildup and make your radiator work twice as long between cleanings, you use distilled water in the cooling system, right? I use distilled water in everything I own. The other common mistake people make is putting too much antifreeze in their cooling system. Never, but never mix it more than 50/50, antifreeze will actually clog the cooling system if it's used in higher than a 50/50 ratio.

            I wonder if the impeller went bad on me. There was no indication of it...whisper-quiet ol flattie engine...I'll go and remove the t-stat. Attempt to go home. Monitor operation.
            Will update when I can....

                Just a quick sugestion Dan, leave the rdiator cap loose and let it run for a bit and see if it starts circulating.

                  Little nervous, don't wish to have a heat problem..I did run it as I mentioned B4, but perhaps not long enough for the t-stat to open. Are you suggesting this prior to removing the stat'?

                    Yes, run it a bit before you take out the t-stat. That way you can check the hoses like Bob suggested and see if it will circulate. Do you have a thermometer that you can stick in the rad? That's the BEST way to tell what you really have. I've thought my car was getting hot until I used the external thermometer in the rad. With the cap loose and it running, it Will bubble over and lose some coolant, but it will let out enough until it's happy with that level, Just keep an eye on it.

                      Well drove home and the lower hose tube is COLD. Very short drive thankfully! Will pull-stat, run it, -ck for flow- and report back l8er

                        pulled the stat. topped off. started. I HAVE A VERY GOOOOOOD WATER PUMP![^][]
                        The lower hose warmed up immediately. Let her run @ idle. Run great, warm lower hose, I left the stat out. I would appear I have 2 bad ones! Now c'mon, 2 bad ones???[}] Recall, I tested the one I had replaced earlier 2day? Well that one was in while I drove home a scant 1.5 mile. So now all you skilled t-shooters, order a stat or run w-out? [B)]I know no stat is a BAD idea,

                          Damn, it's just not circulating. Yeah, please let us know what you find Dan, I'd like to know what it was.....

                            Got to be a baad t-stat. I mean that's it. Wht do ya think of not running with a stat? I guess I'll locate one and replace it. Too bad I have to order the thing. And wait[|)][|)][|)]
