Situation:
JLR Engineering investigations have found a 'Coolant Low' warning message displayed on the Instrument
Panel Cluster.
Cause:
Multiple potential engine coolant leak paths.
Action:
Follow the instruction(s) below.
SERVICE INFORMATION:
Vehicles must be returned to the customer with the engine coolant at the required maximum level and the
correct concentration level.
SERVICE INSTRUCTION:
NOTE: Make sure the outside surface of the coolant expansion tank is dry before completing the coolant
pressure test. Residual engine coolant from a previous top-up may still be present on the outside surface
of the coolant expansion tank.
Pressure test the engine cooling system as detailed in the TOPIx Workshop Manual, (see TOPIx
Workshop Manual section 303-03: Engine Cooling - Diagnosis and Testing - Cooling System Pressure
Test).
Make sure the following components are inspected as part of the cooling system pressure testing
diagnosis:
1. Coolant expansion tank/coolant expansion tank filler cap
2. Coolant expansion tank bleed screw - If leaking then a new coolant expansion tank must be installed
