Top Causes of Coolant Leak in Toyota Innova Crysta

• Radiator hose split or collar seal failure — most common cause
• Water pump seal or gasket leak — weeping from pump housing
• Radiator core leak from stress cracks or corrosion
• Head gasket failure — allows coolant into combustion chamber
• EGR cooler crack (Volvo, BMW diesel) — coolant leaks into exhaust system

How We Diagnose Coolant Leak on Toyota Innova Crysta

• Coolant system pressure test at 1.4 bar — holds pressure if no external leak
• Combustion gas test — checks for head gasket breach into cooling system
• Infrared thermal scan of radiator and hoses for cold spots indicating blockage
• Water pump weep hole inspection and visual scan of all hose clamps

Prevention

Replace coolant every 5 years or 80,000 km — old coolant becomes acidic and corrodes aluminium components.
