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 MITSUBISHI MOTORS GENUINE SUPER LONG LIFE COOLANT PREMIUM without adding
water because the concentration is preadjusted 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)
