Rover 100

Coolant capacity & service interval

Rover 100 coolant capacity ranges from 4,5 to 5,5 liters. Service intervals include 24 months and 40000 km or 48 months. The data covers 5 configurations.

Additional Notes

  • The Rover 100 cooling system capacity holds at 4.5 liters across the 111, 113 Diesel, 114, and 114 GTi variants, while the 115 Diesel stands apart with a 5.5 liter capacity, reflecting the greater thermal demands of a larger diesel engine.
  • A 4.5 liter cooling system fill is a moderate capacity typical of small-displacement engines, where the volume is sufficient to maintain stable operating temperatures without the overhead required by larger powerplants.
  • The 111, 113 Diesel, and 114 all share a 24-month coolant change interval under normal use conditions, with no mileage threshold specified alongside the time-based requirement.
  • The 115 Diesel also carries a 24-month change interval under normal use, pairing a time-based schedule with a notably larger 5.5 liter system volume compared to the petrol variants.
  • The 114 GTi diverges from the rest of the lineup with a change interval expressed as 40,000 km or 48 months under normal use, whichever comes first, making it the only variant in the range to carry a dual time-and-distance schedule.
  • A 48-month coolant change interval, as specified for the 114 GTi, is consistent with the use of long-life or extended-service coolant formulations, which maintain corrosion inhibitor effectiveness over longer periods than standard antifreeze mixtures.
  • The 113 Diesel entered the specification range in 1992, two years after the 1990 start of the 111 and 114 petrol variants, while sharing the same 4.5 liter capacity and 24-month interval as those earlier entries.
  • The 115 Diesel, introduced in 1995, carries the highest coolant capacity in the range at 5.5 liters, a full liter more than all other listed variants regardless of fuel type.
