Engine Coolant Concentration Test

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • Engine coolant of less than 30% concentration has a less rust-proof effect. In a concentration of over 60%, the antifreeze effect and engine cooling performance of the engine coolant are deteriorated, causing a detrimental effect on the engine. Therefore, observe the service concentration range without fail.
  • Use the Dia Queen Super Long Life Coolant Premium without adding water because the concentration is pre-adjusted to 50%.

Using a hydrometer, check if the engine coolant concentration is within the standard value range.

Standard value: 30 to 60% (service concentration range)
