Overheating, coolant loss, warning messages, or unstable temperature readings indicate cooling system failure. Full circuit diagnostics and pressure testing restore thermal management.
BOOK COOLING REPAIRSystem pressurised to OEM spec to locate external and internal leaks — including head gasket seepage that standard inspection cannot detect.
Radiator flush, water pump, thermostat and coolant hose replacement using OEM-spec parts rated for Dubai operating temperatures.
Full coolant flush removes degraded fluid and scale build-up. Refilled with the correct OAT or HOAT coolant to the manufacturer's mixing ratio.
Hallmark Auto Service diagnoses and repairs all cooling system faults — from a leaking hose to a failing water pump or a blocked radiator. Our pressure-test protocol locates leaks that are not visible on inspection.
Live coolant temperature data logged. Engine, cooling fan and thermostat fault codes extracted via diagnostic scan.
System cold-pressurised to 1.4 bar. Leak-down rate measured over 15 minutes identifies all external leak points.
Leaking hoses, radiator, water pump, thermostat or expansion tank replaced as required. Head gasket integrity confirmed with combustion gas test if indicated.
Full coolant system flush. Correct OAT/HOAT coolant mixed to ratio and filled. Air purged from circuit. Temperature verified on road test.
This pattern typically indicates a sticking thermostat or a cooling fan that activates late. Both are diagnosed in our pressure test and scan procedure.
Every 3–5 years or 60,000–100,000 km depending on the coolant type. OAT coolants last longer. Degraded coolant becomes acidic and corrodes aluminium components common in European engines.
Distilled water is acceptable as a temporary measure. Tap water contains minerals that deposit scale. Always refill with the correct pre-mixed coolant as soon as possible.
