Cub Cadet LT 2138 Coolant and Engine Notes
Coolant capacity note
The Cub Cadet LT 2138 coolant spec points to 2.17 gal (8.2 L). Do not rely on the radiator-only amount if the full cooling-system capacity is available
Coolant type note
Coolant type for the Cub Cadet LT 2138 is listed as ethylene glycol-based coolant. The safest move is to use coolant that matches the manual’s spec rather than mixing random formulas
Antifreeze mix note
The 50/50 coolant and water mix mix gives the Cub Cadet LT 2138 coolant system a sensible balance of freeze protection, boil protection and corrosion protection
Coolant change interval note
The captured coolant change interval for the Cub Cadet LT 2138 is every 2,000 hours. Old coolant can lose corrosion protection even if the tractor still runs cool
Engine context note
The Cub Cadet LT 2138 engine data captured here is displacement 0.5 L (30.5 cu in). Bigger engines usually need more coolant and more careful refill bleeding
Refill note
When refilling the Cub Cadet LT 2138, use 2.17 gal (8.2 L) as the planning number and 50/50 coolant and water mix as the mixture guide. Recheck the level after the thermostat opens
