Recommended Coolant

~1min read
  • Use only soft (demineralized) water in the coolant mixture.
  • Your vehicle's engine contains aluminum components and must be protected against corrosion and freezing with ethylene glycol-based coolant.
  • DO NOT USE alcohol-based coolant or methanol, or mix it with the specified coolant.
  • Do not use a mixture containing more than 60% antifreeze or less than 35% antifreeze, as this reduces the effectiveness of the mixture.

See the following table for mixture ratios.

Gasoline Engine

Diesel engine

WARNING

Radiator Cap

Do not remove the radiator cap when the engine and radiator are hot. Hot coolant and steam may escape under pressure and cause serious injury.
