Cub Cadet i1046 Coolant and Engine Notes
Coolant capacity note
The Cub Cadet i1046 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
Radiator capacity note
Radiator capacity is listed as 0.63 gal (2.4 L). The full cooling system can be higher because coolant also sits in the engine and hoses
Coolant type note
For the Cub Cadet i1046, coolant type matters as much as capacity. The clean captured value is ethylene glycol-based coolant
Antifreeze mix note
The 50/50 coolant and water mix mix gives the Cub Cadet i1046 coolant system a sensible balance of freeze protection, boil protection and corrosion protection
Engine context note
The Cub Cadet i1046 engine data captured here is engine horsepower 20 hp (14.9 kW) and displacement 0.7 L (44.2 cu in). Bigger engines usually need more coolant and more careful refill bleeding
Refill note
The practical service move for the Cub Cadet i1046: buy enough coolant for 0.63 gal (2.4 L), fill to spec, run the engine, then recheck the radiator and overflow bottle after cooling
