[C320-list] Ahoy owners with Perkins engines

[Kirk McCullough]

With 2500 hours on my Perkins, I haven't had that problem yet. Look like its fairly easily repairable, good luck.

I had the exact problem.  My diesel guy was able to replace the water pump.
He ordered it from an outfit in New Jersey.
