How often should I replace coolant in my vehicle? Is there a specific interval that I should adhere to, or does it depend on various factors such as the make and model of my car? What about the driving conditions — do extreme temperatures or frequent short trips necessitate more frequent changes? Should I trust the manufacturer’s recommendations, or are there other considerations that I should take into account? What role does the type of coolant I use play in determining replacement frequency? Furthermore, could neglecting to change the coolant affect my engine’s performance and longevity? Are there signs that indicate it’s time for a coolant change, or can it sometimes go unnoticed until it’s too late? How can I gauge whether my coolant has degraded or become ineffective over time? In light of all these factors, what is the best approach to ensure optimal maintenance for my vehicle’s cooling system?
