Additional Notes
- All three configurations of the Tata Indigo CS share a cooling system capacity of 6 liters, which represents the total system fill volume including the radiator, hoses, and reservoir.
- The 6-liter capacity applies uniformly across the 1.4 TDI BS3, 1.2 BS4, and 1.4 TDI BS4 variants, indicating no meaningful difference in cooling system volume between the petrol and diesel engine configurations.
- The coolant change interval is rated at 40,000 km or 24 months under normal use conditions, meaning whichever threshold is reached first would trigger a service.
- The 24-month time limit on the coolant change interval reflects the chemical degradation of coolant additives over time, which occurs independently of mileage accumulation.
- The Indigo CS 1.4 TDI BS3 variant carries a starting year of 2008, making it the earliest configuration in the lineup, while the two BS4 variants both carry a starting year of 2012.
- The Indigo eCS 1.4 TDI BS4 is the only configuration with a defined end year of 2018, while the 1.4 TDI BS3 and 1.2 BS4 variants each carry only a starting year.
- The consistent 40,000 km service interval across all three configurations suggests a standardized coolant maintenance schedule regardless of emission standard or engine displacement.
