Steps to replace coolant in Hyundai ix35: 1. Wait for the vehicle to cool down; 2. Open the radiator and drain valve to release the old coolant; 3. Close the drain valve and fill in new coolant; 4. Start the vehicle and let it idle for 3 to 5 minutes to circulate the cooling system. Taking the 2021 Hyundai ix35 as an example, it is equipped with a 2.0L turbocharged engine, with a maximum horsepower of 160ps and a maximum power of 118kw, paired with a 6-speed automatic transmission. The 2021 Hyundai ix35 has body dimensions of: length 4500mm, width 1850mm, height 1680mm, and a wheelbase of 2640mm.

I just changed the coolant for my Hyundai ix35, and the whole process wasn't too difficult. You need to make sure the car is cooled down first—it's safer after leaving it overnight. Open the engine hood, locate the drain plug at the bottom of the radiator, and loosen it with a wrench, placing a bucket underneath to catch the old fluid. Then, flush the system with clean water to rinse out any residue. After the water drains completely, buy specialized coolant—note that Hyundai vehicles use ethylene glycol-based coolant, the green-labeled one is fine. Pour the new coolant into the expansion tank up to the MAX line, then start the engine for a few minutes to purge air bubbles. Remember to check the fluid level regularly, as aged coolant can corrode components. I usually change it every two years to keep the cooling system efficient.

I was a bit nervous during my first coolant change, but the Hyundai ix35's design is quite user-friendly. Remember to wear gloves and goggles before starting, and ensure the engine is completely cooled. Open the hood, locate the radiator on the left side, and find the drain plug at the bottom. Loosen the plug to let the fluid drain out, using a pan to catch it and avoid ground contamination. Flush the system with clean water to remove old residue, then refill with new coolant at a 50/50 mix ratio up to the expansion tank's marked level. Start the engine and let it idle for 5 minutes, and when replacing the radiator cap, do it slowly to prevent splashing. Beginners often forget to bleed air bubbles, which can cause overheating—it's advisable to drive a short distance after the change and then top up if needed. Safety comes first; if unsure, ask a friend for help or watch a repair video.

Changing the coolant in a Hyundai ix35 is quite straightforward, and I've been doing it since the car was new. After the engine cools down, open the cap and locate the drain plug at the bottom of the radiator—a common cross wrench will do the job. Once drained, flush the system once, and pour in new coolant, making sure not to mix brands. The crucial step is bleeding the air after refilling by running the engine to operating temperature; otherwise, trapped air bubbles can cause overheating. Opt for long-life coolant—it's hassle-free and durable. I usually replace it every two years to maintain the system. Take your time during the process—slow and steady ensures a clean job, avoiding leaks or damaged parts.
