How often should the coolant be replaced in a Nissan Sylphy?

[RyanMarie]

Nissan's recommended coolant replacement interval for the Sylphy is every 32,500 kilometers or 39 months. When replacing the coolant, it's advisable to use the same brand of coolant. Different brands may have varying production formulations, and mixing them could potentially trigger chemical reactions between additives, rendering them ineffective. Prolonged failure to replace the coolant can lead to deterioration in quality, reduced anti-rust properties, damage to components like radiators and pipes, and altered boiling and freezing points, thereby compromising the antifreeze or cooling performance. It's recommended not to wait until the coolant turns black before replacement, as darkened coolant indicates significant deterioration and substantial scale buildup, which may have already caused damage to the piping system.
