  • Surge tank on Avanti

    Should all Studebaker Avanti's have a surge tank? I have a 1963 R-2, R4212A and a 1964 R-1, R5212B. The '63 has the black fiberglass tank which works great, and the '64 has a Mickey Mouse (sort of) arrangement with a "T" joint with a radiator cap, hose from engine to "T" and hose from "T" to radiator, with a plastic overflow hose going to a plastic overflow container mounted on the right front of engine compartment. This does not work as well and often overflows at high rpm's. (I don't have a thermostat as it used to overheat in hot weather). This must imply that the heavy duty water pump is great. What's the answer? Thanks.

    In a word...yes. All Studebaker Avantis came with a surge tank.

      Put the thermostat back in.
      It provides a restriction to slow the flow of coolant.
      Coolant going through too fast does not soak up enough heat.
      If you insist on not running a thermostat, just take the works out of your old one, but put the disc back in.
      But... a slow warmup can cause condensation problems in your oil.

      Question.
      Did you remove all the block plugs and rod out the rearmost cooling passages?

        I don't think that tank is fiberglass -I think they are copper or brass?

        SI sells a kit similar to what you described that replaces the surge tank and that's likely what's been done to yours.

          Read more closely, look more closely. O.K. to be a gunslinger, but look carefully at target before you shoot. Larger photos attached.



          Yes, I know all Avanti's have surge tanks, but some are different than others. Thanks for looking. And to answer the other question raised by DEEPNHOCK, as you can see, the engine's never been touched, and it may well be full of crud. Aren't all old Studebaker blocks full of crud in that location? Yes, and I probably will eventually replace the thermostat. Do you know where I could get a round tuit?

            The tank in the left picture is made of brass and is the part that came with all Studebaker Avanti's. The T with the radiator cap did not come with Studebaker Avanti's but a part like that is used on Avanti II's.

              This is a great thread. My Avanti (dismembered at the moment but in the rebuilding stage) has the T with the radiator cap. It looks just like the photo on the right. Based on David's comments I deduce that some prior owner went with an Avanti II setup. However, there was also a translucent reservoir tucked into the right front corner of the engine compartment that my photos and notes show to have been connected to the cooling system. So, two questions: is the T setup an adequate substitute, and does anybody know what this translucent container is?

              Thanks,

              Tom

                The translucent bottle is a coolant recovery bottle.It is included with the surge tank eliminator kit that Studebaker Internatioal sells, or you can buy just the overflow kit. I have one on my Avanti but still retain the surge tank.

                  Hey Bob,

                  Is the surge tank there for decoration? Or are both functional? And if so, why?

                  BTW, great engine compartment!!

                      The surge tank works. When the coolant gets hot and expands, the bottle catches any coolant that would go to the ground thru the over flow hose on the surge tank. As it cools it is returned to the surge tank.

                      Thanks for the compliment.

                        As I said...all [u]Studebaker</u> Avanti's came with the surge tank...actually, it's an expansion tank, but the words gets used interchangeably. It's brass and painted black, not fiberglass. If a [u]Studebaker</u> Avanti has the "T" joint...it didn't come from the factory that way. It's aftermarket, pure and simple. Avanti Motors started using that type of system in the early 1970's. From 1965 through 1970 at least, they used modified expansion tanks from the Stude built Avanti's.

                          You are absolutely right, it is metal and painted with a black ripple paint. Also shown that way in the shop manual.

                            Absolutely beautiful photo and engine! Where does the hose from brass expansion tank to overflow tank run? You must have made an extra fitting on the brass tank.

                              If you had the space you would have a surge/expansion tank with an air space of about 10% of the coolant volume. This would provide pleanty of expansion space when the coolant was hot without the need for an overflow tank.
