  • Use: Normal
  • Capacity 10 liter
  • Check 20000 miles/ 24 months
Jetta 2.0 TFSI (170 kW) (2021- )
  • Use: Normal
  • Capacity 10 liter
  • Check 20000 miles/ 24 months

Additional Notes

  • Both the Jetta 1.5 FSI (118 kW) and the Jetta 2.0 TFSI (170 kW) share a cooling system capacity of 10 liters, which is a typical total system fill volume encompassing the radiator, engine block passages, heater core, and expansion tank.
  • A 10-liter cooling system capacity is consistent with a full-system service fill rather than a partial top-off, meaning the figure reflects the total volume required when the system is drained and refilled from empty.
  • The coolant check interval for both the 1.5 FSI (118 kW) and the 2.0 TFSI (170 kW) is set at 20,000 miles or 24 months under normal use conditions, whichever comes first.
  • The 24-month time-based component of the check interval means that even in low-mileage operation, a coolant inspection is due within two years regardless of distance traveled.
  • Despite the difference in displacement and output between the 1.5 FSI (118 kW) and the 2.0 TFSI (170 kW), the Volkswagen Jetta carries identical cooling system capacity and check interval specifications for both engines in the 2021 model year.
