Its dataplate shows Positech Intl, I called the 3 telephoine numbers on the data plate and all are disconnected and google shows them closed permanently. Where can I send the oil cooler to be clean and inspected?

We know from experience that no amount of chemical cleaning can dislodge it, and you must send it to a facility that has a heavy duty ultrasonic machine and the vibration is the way to get rid of this hardened oil!
