The Nissan Sunny uses a 1.5 HR15 petrol (99 bhp) and is classified as a sedan. Based on our workshop experience with Nissan Sunny in Hyderabad: 1.5 K9K diesel EGR valve soot — same family as Renault diesel. We also see white smoke from exhaust in vehicles that share similar engine architecture to the Nissan Sunny.
Never continue driving with an overheating engine — one episode of severe overheating can cause the head gasket failure that leads to white smoke.
Is white smoke always a head gasket?
Persistent white smoke from a warm engine is almost always head gasket until proven otherwise. The combustion gas test confirms it in 5 minutes. Cold-start white puff that clears quickly is normal condensation. GarageNation does the combustion gas test as part of the ₹1,500 diagnostic scan — never pays to guess on head gasket.
