ENGINE COOLANT CONCENTRATION CHECK <4B1, 6B3>


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.
Using a hydrometer, check if the engine coolant concentration is within the standard value range.
Standard value: 30 to 60% (service concentration range)
