Where is the coolant drain valve located on the Teana?

The coolant drain valve on the Nissan Teana is located at the bottom of the radiator. The method for replacing the coolant is as follows: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with particular attention to the five-way hose. The coolant flows through the five-way hose and is then distributed to different parts of the car to perform its function. If there is any leakage of coolant in this section, replace the hose or re-secure the connection as needed. Drain the old coolant, then flush the liquid channels with clean water. Add water to the coolant reservoir and continue filling it until clean water flows continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the reservoir will have a faint pink color. Continue adding clean water until the outflow is clear. Note: Don't forget to remove the heater hose and drain the water from the heater core. After draining for about an hour, add the new coolant through the radiator hose. Then, pour another container of coolant into the coolant reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level will drop slightly as air is purged from the cooling system. Top up the coolant to the "MAXT" mark on the reservoir.
I've been driving my Teana for several years and usually do the maintenance myself. The coolant drain valve is located at the bottom right of the radiator. Before changing the coolant each time, I always let the car cool down completely to avoid burning my hands. Use a wrench or a Phillips screwdriver to gently loosen the valve, and place a bucket underneath to catch the waste fluid. The radiator is at the front of the engine, and you can easily reach the valve by leaning over. Regularly changing the coolant is crucial, as rust in the pipes can lead to serious issues. Always wear gloves for safety when doing this yourself. As the car ages, make it a habit to check these things—it can save you a lot on repair costs. Don't delay too long; it's best to change it every two to three years.
