Tata Nano

Coolant capacity & service interval

Tata Nano coolant capacity ranges from 2,4 to 8,3 liters. Service intervals include a 10000 km or 12 month check and a 40000 km or 24 month change. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Tata Nano cooling system capacity is 2.4 liters in configurations without a heater, rising to 4 liters when a heater is included, a difference that reflects the additional fluid volume held within the heater core and its connecting hoses.
  • The Nano GenX (2015-2018) with an automatic transmission and heater carries a notably larger 8.3-liter cooling system capacity, while the same transmission without a heater holds 7.2 liters, pointing to a substantially more complex cooling circuit compared to manual transmission variants.
  • Across the Nano (2008-2014) and Nano CNG eMax (2013-2018), the coolant change interval is set at 40,000 km or 24 months under normal use conditions, whichever comes first.
  • The Nano GenX and Nano Twist both carry an additional coolant check interval of 10,000 km or 12 months, a periodic inspection point that sits between full drain-and-fill services and is absent from the earlier Nano and Nano CNG eMax specifications.
  • The Nano CNG eMax (2013-2018) shares identical cooling system capacities and change intervals with the standard Nano (2008-2014), indicating the compressed natural gas powertrain did not alter the cooling circuit volume or service schedule.
  • The Nano GenX automatic transmission variants show a capacity gap of 1.1 liters between heater-equipped and non-heater configurations, while manual transmission variants show the same 1.6-liter gap seen across all other Nano variants, suggesting the heater circuit volume contribution differs between transmission types.
  • The 40,000 km or 24-month coolant change interval is consistent across all four variants under normal use conditions, making the service schedule uniform regardless of transmission type or fuel system.
