Cub Cadet 2135 Coolant and Engine Notes
Coolant capacity note
The Cub Cadet 2135 coolant spec points to 0.63 gal (2.4 L). Do not rely on the radiator-only amount if the full cooling-system capacity is available
Coolant type note
The captured coolant type for the Cub Cadet 2135 is ethylene glycol-based coolant. Do not mix unknown coolant types unless the label and manual say they are compatible
Coolant change interval note
The captured coolant change interval for the Cub Cadet 2135 is every 6,000 hours. Old coolant can lose corrosion protection even if the tractor still runs cool
Engine context note
The Cub Cadet 2135 engine data captured here is engine horsepower 13 hp (9.7 kW) and displacement 0.4 L (24.3 cu in). Bigger engines usually need more coolant and more careful refill bleeding
