Yes, I have a 2GM with a Sendure heat exchanger. My documentation indicates that it delivered that way from T-P.
Once I had to yank it to take to a radiator shop when the solder joint with a mounting bracket failed; it was no big deal. Based upon that experience I recommended to Mark that he take it to radator shop to have it boiled out and inspected.
The sacrificial zinc requires annual replacement. I have replaced the end caps and gaskets twice. On the whole it has been very reliable.
