Hyundai Elantra, AD (EU)

Coolant capacity & service interval

Hyundai Elantra, AD (EU) coolant capacity ranges from 5,6 to 6,7 liters. Service intervals include 30000 km/ 24 months, 40000 km/ 24 months, 60000 km/ 48 months, 100000 km/ 60 months, and 200000 km/ 120 months. The data covers 6 configurations.

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

Additional Notes

  • The Hyundai Elantra AD (EU) 1.6 CRDi cooling system holds 6.7 liters, which is notably larger than the 1.6 MPI variants, reflecting the additional thermal demands of a diesel engine with its associated cooling circuit components.
  • The 1.6 MPI engine introduces a capacity split depending on transmission type: 5.6 liters with an automatic transaxle and 5.7 liters with a manual transaxle, a difference that stems from variations in heat exchanger routing between the two drivetrain configurations.
  • For the 1.6 CRDi and 1.6 CRDi DPF under normal use conditions, coolant changes are scheduled at 40,000 km or 24 months, whichever comes first, across the 2016-2018 model range.
  • The 1.6 CRDi and 1.6 CRDi DPF carry a first change only interval of 100,000 km or 60 months, meaning the factory-fill coolant is intended to remain in service significantly longer before the first drain, after which the normal 40,000 km / 24-month cycle applies.
  • The 1.6 MPI under normal use conditions carries both a check interval and a change interval set identically at 30,000 km or 24 months, indicating that inspection and replacement are aligned to the same service point rather than staggered.
  • Under initial service conditions, the 1.6 MPI coolant change interval extends substantially to 200,000 km or 120 months, which represents a ten-year or 200,000 km factory-fill service life before the first scheduled replacement.
  • The initial service check interval for the 1.6 MPI is set at 60,000 km or 48 months, meaning the cooling system is inspected at that point well before the 200,000 km / 120-month change milestone is reached.
  • The 1.6 CRDi DPF shares identical capacity and interval specifications with the standard 1.6 CRDi across both the normal and first change only use conditions, with both variants covering the 2016-2018 period.
