Can I drive with an overheating engine?
No — stop immediately when the temperature gauge enters the red zone. Driving a hot engine for even 2–3 minutes can warp the cylinder head (₹40,000–₹1,50,000 repair) or blow the head gasket (₹25,000–₹75,000). Pull over, switch off, and call GarageNation for free pickup: +91 8106316369.
Is engine overheating always the head gasket?
No — most overheating is caused by a faulty thermostat (₹3,500–₹8,000) or a coolant leak (₹5,000–₹25,000). Head gasket failure is less common but diagnosed by the combustion gas test — if gases are in the coolant, the head gasket is compromised. GarageNation always does the combustion test before recommending head work.
