Atlas Copco Unexplained Coolant Loss

Generator coolant level drops over time with no visible external leaks

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Small leak in radiator core, Leaking water pump seal, Head gasket seep, Coolant evaporation from overflow

Safety first: Only open the cooling system when cool. Use appropriate coolant, not plain water, unless specified for temporary use.

Pressure test: Have the cooling system pressure‑tested to reveal small leaks.
Inspect water pump: Look for dried coolant around the pump weep hole.
Check exhaust: White smoke and sweet smell may indicate coolant burning in cylinders.
Monitor closely: Mark the coolant level and track loss rate. Rapid loss requires immediate professional attention.
