Greetings,
After discovering a coolant leak from around the sealing ring of the plastic fitting where the little hose from the top of the expansion tank attaches to the radiator (27 in the figure below) I started to remove the hose from the barb and the end of the fitting came off - apparently it was broken or badly cracked about where the thread starts in the radiator.
I will be taking the radiator out tomorrow evening to get a better look but right now I don't see any sign that the threads on the radiator that that piece threads into are metal - so I ask: Assuming plastic threads on the radiator, does anyone have any suggestions as to how to get the remains of the broken-off plastic fitting out of the plastic radiator threads without damaging those threads (or preferably tell me that I am wrong and that the radiator threads are indeed a metal insert like where the fan switch is.)?
Thanks!
