Additional Notes
- Both the 2.5i and 4.0i engine variants of the Jeep Comanche MJ (EU) share an identical cooling system capacity of 9.5 liters, which represents the total volume of coolant the system holds when filled to specification.
- A 9.5-liter cooling system capacity is a moderately sized figure for a compact pickup truck platform, reflecting the thermal demands of both the four-cylinder and inline-six engine configurations available in the Comanche MJ lineup.
- The coolant change interval for both engine variants under normal use conditions is set at 85,000 km or 24 months, whichever comes first, meaning time elapsed can trigger a service requirement even before the mileage threshold is reached.
- The 24-month time-based component of the normal-use interval reflects the chemical degradation of coolant additives over time, which occurs independently of vehicle mileage accumulation.
- The 85,000 km distance threshold in the normal-use interval is a relatively extended mileage figure for coolant service, consistent with long-life coolant formulations that were becoming more common in late 1980s and early 1990s vehicle specifications.
- The fact that the 2.5i four-cylinder and the 4.0i inline-six share the same 9.5-liter capacity and identical service interval suggests the Comanche MJ platform uses a common cooling system architecture across both engine options in the EU specification.
