Hürlimann XL
Coolant capacity & service interval
Hürlimann XL uses coolant with a capacity range of 17,5 to 28 liters. Service intervals include checks every 10 hours and changes every 24 months. The data covers 5 configurations.

Additional Notes
- The Hürlimann XL 130 and XL 150 share a cooling system capacity of 17.5 liters, while the XL 150.7, XL 165.7, and XL 180.7 each require 28 liters, reflecting a notably larger cooling system in the .7-series variants.
- The 28-liter capacity of the .7-series models is 60% greater than the 17.5-liter figure seen in the XL 130 and XL 150, a difference that points to a substantially larger or more thermally demanding engine configuration in those variants.
- Across all five configurations covering 2006-2009, the coolant change interval is set at 24 months under normal use conditions, making calendar time rather than operating hours the governing factor for coolant replacement.
- A 10-hour check interval applies to the cooling system on all five models, indicating that coolant level and condition are to be inspected very early in the service cycle, consistent with the critical role coolant plays in engine temperature regulation.
- The XL 150 and XL 150.7 carry the same model-year range of 2006-2009 but differ significantly in cooling system capacity, with the XL 150 at 17.5 liters and the XL 150.7 at 28 liters, demonstrating that the .7 designation marks a distinct mechanical specification rather than a minor trim variation.
- All specifications listed apply under normal use conditions, meaning the 24-month change interval and 10-hour check interval are not adjusted for more demanding operating environments in the data provided for these models.
