Landini 4600 series
Coolant capacity & service interval
Landini 4600 series uses coolant with a capacity range of 3 to 6 liters. Service intervals require changes every 1000 hours or 12 months. The data covers 8 configurations.

Additional Notes
- Cooling system capacities across the Landini 4600 series vary directly with engine displacement. The 3TNV76-XVA is a three-cylinder engine with a smaller bore, and the 3-liter cooling system capacity reflects the reduced thermal load of that configuration.
- The Yanmar 3TNV88-BKVA, fitted to the 4645 variants, carries a 5-liter cooling system. The larger bore of the 88-series block compared to the 76-series accounts for the increased coolant volume required to maintain operating temperatures.
- The 4655 models use the Yanmar 4TNV88-BKVA, a four-cylinder version of the same 88-series block. Adding a fourth cylinder raises the cooling system capacity to 6 liters, the largest figure across the 4600 series specifications listed here.
- All eight configurations share an identical coolant change interval of 1,000 hours or 12 months under normal use conditions, whichever comes first. The dual-trigger structure means calendar time can mandate a change even when the hour threshold has not been reached, which is relevant for low-utilization machines.
- The ARM, ISM, and VRM designations on the 4645 and 4655 models refer to different transmission or control configurations, yet all share the same engine and the same cooling system capacity within each model number. The 5-liter figure applies uniformly across all three 4645 variants, and the 6-liter figure applies uniformly across all three 4655 variants.
- The 4630 ARM and 4630 ISM both use the 3TNV76-XVA engine and carry a 3-liter cooling system capacity. No VRM variant is listed for the 4630, making ARM and ISM the only two transmission configurations specified at that engine size.
