P2560 Engine Coolant Level Low

Check engine lightUsually off

P2560 is not an electrical fault but a level finding: the coolant level sensor works, yet it reports less coolant than the minimum. Deutz uses it on the EMR L1 control as P2560-00 under SPN 111 with failure mode 1, meaning the level has fallen under its warning threshold. Ford lists P2560 in the 2014 BOSS 302S engine module table, with no M in the lamp column, i.e. no MIL. Mercedes-Benz reports the same situation differently, under P2556-7B. The usual causes are leaks at hoses, radiator, water pump or heater core, internal leaks such as a charge air cooler or head gasket, or air trapped after a service. Because overheating can follow, top up only with the engine cool and look for the loss. P2556 to P2559 cover faults of the level sensor and its circuit.

Likely causes

External leak at hoses, radiator or water pump
Internal leak, e.g. charge air cooler or head gasket
Air trapped after a coolant service

Symptoms

  • Low coolant warning
  • Rising engine temperature or overheating
  • Visible coolant traces or sweet smell
