Can I replace the coolant myself?

Coolant can be replaced by yourself. The replacement steps are: First, wait for the vehicle to cool down. Never replace the antifreeze when the engine is hot. Drain the old coolant - there are several methods for this. After the original coolant is completely drained, you can add new coolant. Coolant, also known as antifreeze, primarily functions to maintain the engine within a normal operating temperature range during operation, while also providing anti-freeze, anti-boil, and anti-corrosion protection. Generally, automotive coolant should be replaced every two years or 40,000 kilometers. The antifreeze in the reservoir can be siphoned out or removed and poured out. After reinstalling, add new antifreeze between the upper and lower level marks. During use, observe the fluid level and replenish antifreeze promptly if it drops.
Of course you can change the coolant yourself, I do it all the time because DIY coolant replacement saves a lot on repair costs. First, prepare tools like a wrench, new coolant jug, and a large pan to catch the old fluid—make sure the car is completely cooled down before starting, or you might burn your hands. Then locate the drain valve or radiator cap and slowly open it to drain the old fluid; this process can get messy, so lay down a cloth. After draining, if you suspect debris in the system, you can flush it with water, but don’t forget to refill with fresh coolant to the proper level. Be sure to pick the right antifreeze type—don’t mix red, green, or blue varieties, or the engine will suffer. It’s best to run the engine for a few minutes while cold to check for leaks. Overall, DIY isn’t hard—spending a little time each month on maintenance ensures the engine won’t overheat in summer or freeze in winter, plus you’ll save $50 on labor. Worth it!
