Hyundai Genesis, BH (USA)

Additional Notes

• The Hyundai Genesis BH (USA) cooling system capacity for both the 3.8 GDI V6 (2012-2014) and the 3.8 MPI V6 (2009-2012) is 8.4 liters, a figure that applies equally to normal service intervals and initial service intervals across both induction variants.
• The 4.6 MPI V8 in the 2009-2012 configuration carries a cooling system capacity of 11.5 liters, while the same engine designation in the 2012-2014 configuration specifies a notably larger 13.5 liters, representing a 2-liter increase between the two production periods.
• The 5.0 GDI V8 (2012-2014) cooling system capacity is rated at 12.1 liters, placing it between the two 4.6 MPI V8 capacity figures across the model range.
• Under normal use conditions, every engine configuration listed specifies a coolant change interval of 30,000 miles or 24 months, whichever comes first.
• The initial service interval across all listed configurations extends to 120,000 miles or 120 months, which is four times the mileage and five times the time span of the normal service interval.
• The 120,000-mile or 120-month initial service interval reflects the extended service life of a factory-fill coolant charge, which is formulated to remain effective longer than a standard replacement fill before the first scheduled change.
• The V6 configurations, both the 3.8 MPI and 3.8 GDI, share an identical 8.4-liter capacity despite representing different fuel delivery technologies, indicating the cooling circuit volume remained consistent across the induction change for that displacement.
