Isuzu NHR

Coolant capacity & service interval

Isuzu NHR coolant capacity ranges from 8,6 to 10 liters. Service intervals require changes every 40000 km or 48 months. The data covers 2 configurations.

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

TypeSpecifications
NHR 55 (1996-2007)
  • Use: Normal
  • Capacity 10 liter
  • Change 40000 km/ 48 months
NHR 69 (1996-2007)
  • Use: Normal
  • Capacity 8,6 liter
  • Change 40000 km/ 48 months

Additional Notes

  • The Isuzu NHR 55 carries a cooling system capacity of 10 liters, while the NHR 69 holds 8.6 liters, reflecting a difference of 1.4 liters between the two variants across the 1996-2007 model range.
  • Both the NHR 55 and NHR 69 share an identical coolant change interval of 40,000 km or 48 months, whichever comes first, under normal use conditions.
  • The 48-month time limit on the coolant change interval means a vehicle covering low annual mileage would still require a coolant change within four years regardless of distance traveled.
  • A 40,000 km service interval for coolant is a moderately frequent schedule, consistent with the demands placed on light commercial diesel cooling systems operating under normal conditions.
  • The NHR 55 cooling system capacity of 10 liters is a relatively substantial fill volume for a light truck, indicating a larger engine block and associated cooling circuit compared to the NHR 69.
  • The NHR 69 cooling system capacity of 8.6 liters applies uniformly across the full 1996-2007 production span covered in the specifications, with no variation by model year recorded for that variant.
