Additional Notes

  • The PAZ 3203's 320302-11 CNG variant carries a coolant capacity of 50 liters for the cooling system, which is a notably large volume reflecting the demands of a full-size bus platform rather than a passenger car or light commercial application.
  • Under normal use conditions, the 320302-11 CNG configuration calls for a coolant check interval of 12 months, meaning the fluid level and condition are assessed annually without necessarily performing a full drain and refill.
  • The change interval for coolant in the 320302-11 CNG variant is set at 24 months under normal use, placing a full coolant replacement on a two-year cycle distinct from the more frequent annual check.
