Low coolant
Even a slow leak lowers the coolant level and reduces cooling.
COMMON FAILURES01 02 03
Engine overheating
A temperature above normal means the engine is no longer shedding enough heat. Act quickly to avoid engine damage.
Possible causes
Cooling fan or thermostat
A cooling fan that fails to switch on or a stuck thermostat prevents temperature regulation.
Water pump or radiator
A worn pump or clogged radiator restricts coolant circulation.
