Engine Coolant

~1min read

The high-pressure cooling system has a reservoir filled with year-round antifreeze coolant. The reservoir is filled at the factory.

Check the freeze protection and coolant level at least once a year, at the beginning of the winter season, and before driving in a colder climate.

NOTICE

  • When the engine has overheated due to low engine coolant level, adding engine coolant suddenly may cause the engine to crack. To prevent damage, add coolant slowly in small amounts.
  • Do not drive without engine coolant. This may cause the water pump to fail and the engine to seize, etc.
