Claas Lexion 7000

Additional Notes

• The Claas Lexion 7000 series cooling system capacities vary by engine configuration, ranging from 68 liters on CS86-equipped 7400 and 7500 models up to 80 liters on CS85-equipped 7600 and 7700 models. A 68-liter cooling system is a substantial volume, consistent with the large-displacement engines found in full-size combine harvesters.
• The CS85 engine variant, fitted to the Lexion 7600 and 7700, carries an 80-liter coolant capacity. The CS86 variant in the same model tiers holds either 68 or 72 liters depending on emissions certification, making engine type the primary driver of cooling system size within a given model designation.
• Lexion 7600 and 7700 models equipped with the CS86 engine under Tier 3/Stage IIIA emissions certification carry a 72-liter coolant capacity, which is 8 liters less than the CS85 counterpart in the same model tier. Tier 3/Stage IIIA represents an older emissions standard, and engines built to that certification can differ meaningfully in cooling architecture from later-standard engines.
• The change interval for most configurations is expressed as 48 months, a time-based measure rather than an hours-based one. A 48-month interval spans four years and is typical for modern extended-life coolant formulations used in heavy equipment.
• The Tier 3/Stage IIIA CS86 configurations in the 7600 and 7700 use a 3000-hour change interval rather than a calendar-based interval. An hours-based interval ties coolant service directly to machine operation, which is a common approach for equipment that may accumulate working hours at varying rates across seasons.
• The 7400 and 7500 models, both fitted with the CS86 engine, share an identical 68-liter capacity and a 48-month change interval. The 7500 is available in both wheeled and TerraTrac configurations, yet the cooling system specification remains the same across both chassis variants.
