Additional Notes

  • The MG-ZT 1.8T 160 carries a cooling system capacity of 6.2 liters, the smallest figure across all MG-ZT variants listed, which reflects the comparatively compact displacement of a turbocharged four-cylinder engine.
  • Both CDTi diesel variants, the 120 and 135, share an identical cooling system capacity of 8.2 liters. Diesel engines typically generate higher thermal loads than equivalent petrol units, and the larger coolant volume relative to the 1.8T supports sustained heat management under normal operating conditions.
  • The two V6-24V variants, rated at 160 and 190 horsepower respectively, also share an identical capacity of 7.5 liters. Despite the power difference between the two, the shared engine architecture results in a common cooling system volume.
  • The MG-ZT 260 V8 holds a cooling system capacity of 12.61 liters, by a considerable margin the largest figure among all listed variants. A V8 engine presents a greater total surface area requiring thermal regulation, which accounts for the substantially higher coolant volume.
  • The check interval of 25,000 km or 12 months, whichever comes first, applies under normal use conditions to the 1.8T 160, both CDTi variants, and both V6-24V variants. The time-based component of the interval means a coolant condition check is due annually regardless of distance traveled.
  • A coolant change interval of 48 months is specified under normal use for the 1.8T 160, the 120 and 135 CDTi, and the 160 and 190 V6-24V. A 48-month interval is a standard long-life coolant service cycle, reflecting the use of modern ethylene glycol-based antifreeze formulations that maintain corrosion inhibitor effectiveness over multi-year periods.
  • The CDTi variants cover the years 2003-2005, a narrower production window than the V6-24V variants, which span 2001-2005. The 1.8T 160 falls in between at 2002-2005, while the V8 260 has the shortest listed span at 2004-2005.
