Yanmar 04JHE- heat exchanger ($500)and oil cooler ($200). Both are used. Removed from a well maintained and functioning yanmar 4 cylinder diesel from a sailboat. The motor had 5,000 hours. I rebuilt the motor and replaced these parts as part of the complete rebuild.
Pictures will be placed on ad as soon as I return to the boat.
Text or email first, I do not answer unknown numbers.
