Our Fairfield NJ branch received a service call for a diesel generator low coolant level alarm at a critical Power Facility.
A tech was dispatched immediately and arrived onsite within 30 minutes of receiving the call.
After a thorough inspection, the tech determined there was a coolant leak coming from the factory block heater’s upper hose.
The tech fixed the hose, ran the unit under load, and confirmed there was no more coolant leaking. He topped off the coolant and left the unit operational and back in automatic mode.
The block heater was written-up for replacement and the same tech went back to replace it the following day to prevent any future issues.
