Hi all
Over the weekend i helped a buddy with his golf. We bypassed hes heatercore as it was leaking a crap load into the car. We searched high and low for a U-bend pipe. We found a U-bend pipe at Brights hardware and the 2 screw in fittings to fit the hoses onto, all in steel.
I used heavy duty thread tape to seal but by the looks of things the tread tape is not coping with the heat or i did the application wrong.
Does thread tape work and i made an error or is there something else i should use?
Its only leaking at the one joint but one drop every 10 seconds or so only when at operating temperature.
Input would be gladly appreciated.

Re: Heatercore bypass help needed
Use a 90 degree or U bend pipe that is the same size as the internal diameter of the water pipes.
No other fitings or thread tape or other things needed. Just clamps.
Done many many heater bypasses before and not one has leaked.

Re: Heatercore bypass help needed
Thanks for the advice.
That was our end goal to use but for some reason we just can't seem to find any u beds at all. Im busy speaking to an engineering shop but they not getting back to me as the job is maybe to small for them

Re: Heatercore bypass help needed
I normally just use a single plastic 90 degree. Don't really need it to be a U. The pipes will flex enough to let the 90 deg work.

Re: Heatercore bypass help needed
I bought a metal hollow (similar diameter to core pipes) hanger shaped like a J and ended up cutting off the horizontal part to be left with a U type joint. Use this and hose clamps to secure. Initially looked for copper U joints but seems only aircon suppliers have, then I saw the metal bike / hose hanger, still functional.
