MERCEDES-BENZ COOLANT LEAK REPAIR

Melbourne Euro specialises in Mercedes-Benz coolant leak diagnosis and repair in Melbourne.

If your Mercedes is displaying a “Check Coolant Level” warning, losing coolant, overheating or leaving coolant underneath the vehicle, we can pressure-test and diagnose the cooling system to locate the source of the leak.

We repair cooling-system faults across Mercedes-Benz petrol, diesel and Mercedes-AMG vehicles.

COMMON MERCEDES COOLANT LEAKS

Mercedes-Benz cooling systems contain numerous hoses, seals, plastic fittings and electronically controlled components that can deteriorate with age and heat.

Common coolant leak areas include:

• Water pumps
• Thermostats and thermostat housings
• Radiators
• Expansion tanks
• Coolant hoses and pipes
• Plastic coolant fittings
• O-rings and seals
• Turbocharger coolant lines
• Oil cooler / heat exchanger seals
• Heater hoses and connections

Correct diagnosis is important because coolant can travel across the engine before dripping, making the source difficult to identify visually.

MERCEDES WATER PUMP REPAIR & REPLACEMENT

A failing Mercedes-Benz water pump can cause coolant loss, overheating or poor coolant circulation.

Common symptoms include:

• Coolant leaking from the engine
• Low coolant warning
• Engine overheating
• Coolant smell
• Repeated coolant top-ups
• Temperature fluctuations

Melbourne Euro can diagnose and replace faulty Mercedes-Benz water pumps using suitable quality replacement components.

MERCEDES THERMOSTAT & HOUSING LEAKS

Mercedes thermostat assemblies and housings can develop leaks or thermostat operation faults.

A faulty thermostat can cause:

• Engine running too hot
• Engine running too cold
• Temperature fluctuations
• Poor heater performance
• Check engine light
• Coolant leaks

One of the most common fault codes to appear is P0128, which means “Coolant Temperature Below Thermostat Regulating Temperature”.

We can diagnose whether the problem is caused by the thermostat, housing, seal or another cooling-system component.

MERCEDES RADIATOR & COOLANT HOSE LEAKS

Radiators, hoses and cooling-system connections can deteriorate over time due to repeated heating and cooling cycles.

Common signs include:

• Coolant underneath the vehicle
• Visible coolant residue
• Low coolant warning
• Coolant smell after driving
• Steam from the engine bay
• Engine temperature increasing

We inspect the cooling system and repair or replace the affected components as required.

MERCEDES “CHECK COOLANT LEVEL” WARNING

If your Mercedes displays:

CHECK COOLANT LEVEL • COOLANT LEVEL LOW • ENGINE TEMPERATURE WARNING • STOP VEHICLE / ENGINE OVERHEATING

do not continually top up the coolant without investigating why it is disappearing.

The problem could be a relatively small external leak, but continued coolant loss can eventually cause engine overheating and serious engine damage.

MERCEDES COOLANT LEAK PRESSURE TEST

Some coolant leaks only appear when the cooling system is hot and pressurised.

Our diagnostic process can include:

✓ Cooling-system pressure testing
✓ Visual inspection for coolant leaks
✓ Water pump inspection
✓ Thermostat and housing inspection
✓ Radiator and hose inspection
✓ Coolant reservoir inspection
✓ Fault-code diagnosis where required

Once the source is identified, we can recommend the appropriate repair.

MERCEDES COOLANT LEAK BUT NO VISIBLE LEAK?

Losing coolant without seeing a puddle underneath the vehicle does not mean the cooling system is leak-free.

Coolant may:

• Leak only when the engine is hot
• Evaporate from a hot engine component
• Collect underneath covers or within the engine valley
• Leak slowly from a seal or fitting
• Be lost internally

If your Mercedes requires regular coolant top-ups, the cooling system should be inspected.

MERCEDES-AMG COOLANT LEAK REPAIRS

Melbourne Euro also diagnoses and repairs cooling-system faults across supported Mercedes-AMG models.

High-performance AMG engines can use complex cooling systems incorporating multiple coolant circuits, pumps, radiators and heat exchangers.

Correct diagnosis is particularly important before replacing expensive cooling-system components.
