  • OT- Fusing radiator hose

    I have a 1973 MGB. The lower radiator hose has a 1" hose fused directly to it to circulate the heater core. Well, the darn thing is leaking (actually seeping) at the fused joint. It's a fairly new hose assembly and I hate to write it off.

    Anyone know of a good way to either re-fuse the joint or repair it it in some other manner?



    Thanks,
    Mark

    Maybe an innertube patch kit?

      Bicycle tire patch kit?

      Use the vulcanizing compound inside the hole- car tire kits often come with a sort of "rat tail file" rasp for cleaning the hole to get fresh rubber. Once it's cured, cover the outside with a bicycle tire patch.

      No guarantees, but it's worth a try.

        That's a tough one. I assume the system is pressurized, which means to have any luck at all you will probably have to patch it from the inside. Even if it's not pressurized your best chance of success is an inside patch.

        It looks as though you can sort-of reach the area from the end of the hose. I think I would buy some ShoeGoo (check its working temperature range to be sure it can take the heat), clean the inside surface of the hose with maybe lacquer thinner or something and abrade it to get a good bonding surface, and glop a bunch of ShoeGoo on the inside, covering the leak. ShoeGoo is a thick clear gel that is incredibly sticky and dries to a rubbery, flexible mass.

          Get some brass or copper tubing, and solder up a new piece eliminating that dumb set up, not original but certainly will eliminate that problem.

          Just make up a "T".

              The earlier models had a cast steel elbow fitting with a nipple screwed in the top that used 3 "normal" hoses. I had a couple in my toolbox but gave them away to a friend in the business along with a bunch of other stuff I drug home when I worked for the local dealer. Wish I had all that stuff now.

                I would do as aboard_epsilon suggested and buy a new one as well.
                Rad hoses are like wiper blades fan, belts, etc., expendables not worth fixing.

                I did a quick search and found lots of sources for molded lower rad hoses like yours, anywhere from $9.95 to $30 for a nice blue silicone one that will last longer than the car itself.
                I've had MGs and Triumphs before so I know this to be true.

                I'm sure one of your favorite auto parts sources would find one without any trouble. Hey it's got to come off anyway in order to attempt a fix, may as well be done with it once it's off.

                  I concur. I'll buy a new hose.... but not from Moss Motors or Victoria British. This hose has been pressurized MAYBE six times. Chinese made for British cars!

                    Ugh, Car parts piss me off. Can't even use a standardised hose.

                      Measure the inside of the two hoses and make a brass "T" make 3 cuts and use three hose clamps and tell the Chinese auto parts makers to ************** if you get my drift. Peter

                        Peter, to me the hose looks new.
                        It appears the OP has already spent good money for a replacement molded hose and received junk for his money.
                        No sense using what is obviously material of dubious quality. The repair procedure may be sound, but other than the brass pieces the hose may not last any longer than it did before.

                        Look for a blue silicone molded hose.
                        I see a lot of these type of hoses on construction equipment...they last, and are available for your MG.

                          I too would split the hose and make a T adapter to repair it. That setup looks like a good place to loose an engine from hose failure. If you take it to car shows have an original hose to put on it at the meet. Just leave the coolant out and change the hose back at the end of the meet.

                            Actually, it's supposed to be molded in one piece, but the lack of fillets and improperly designed dies conspire to make these things leak.

                            I'd go with the idea of replacing a segment of the hose with brass pipe with the correct heater hose fitting soldered on.

                            A lot of late model cars and trucks use this same method on their hoses. If you wanted o try keeping the hose looking like the original, you might go to a well stocked auto parts store and ask to look at their stock of replacement hoses. There's a very good chance one of the replacement hoses (designed for another car) would be a perfect match with a little shortening here and there.. When I worked at an auto parts store, I was always amazed at the huge variety of hoses of all different shapes and sizes that were available.

                            Just don't get a parts guy with purple hair and a bunch of tats to help you.
