How coolant-loss symptoms are differentiated
An external coolant leak, internal coolant loss, trapped air, thermostat malfunction, water-pump control fault and radiator/fan problem can all trigger overheating. On supercharged V6 and V8 vehicles, inspect applicable crossover pipes, thermostat housings, pumps and related connections; on Ingenium engines identify the correct cooling circuit and electric pump arrangement. Pressure-test a cold system, examine dried residue and compare sensor readings as temperature rises. Never assume a plastic pipe is the cause without locating the leak.
Manufacturer-specific considerations
JLR Special Service Message 74856 discusses coolant pump codes P2B61-73 and P26CB-72 in certain Ingenium 2.0 petrol applications, with a specific campaign history. That information is an applicability example, not a universal diagnosis.
Repair confirmation
Following repair, use the correct fill/bleed procedure, verify fan and pump operation and confirm temperature stability. Stop driving if the engine is overheating.
An overheating message or coolant loss should be evaluated according to the specific engine and powertrain, including electrified variants where equipped.
How the concern should be diagnosed
Check for leaks and abnormal cooling operation, inspect accessible components and review relevant thermal-management codes.
