How to Replace Coolant for Kia K3?
2 Answers
Kia K3 coolant replacement method is: 1. Before replacing the coolant, check the pipes for any signs of leakage; 2. Drain the old coolant, then flush the liquid channels with clean water, allowing the water to continuously flow through the engine cooling system until the water coming out is clean; 3. Add the new coolant through the radiator hose until it reaches the MAXT mark on the reservoir. The Kia K3 is a compact family sedan with dimensions of 4600mm in length, 1780mm in width, and 1445mm in height, and a wheelbase of 2700mm. The vehicle is equipped with intelligent configurations such as the Smart Connectivity System 2.0 and DRIVEWiSE Smart Safety Assist System.
I really enjoyed changing the antifreeze for my Kia K3 by myself—it felt like fixing a toy. Remember to wait until the car has completely cooled down for several hours before starting. Opening the expansion tank cap on a hot engine is extremely dangerous, as the escaping steam can cause serious burns. I prepared a wrench and a basin to catch the old fluid, then opened the drain valve under the engine to let the old fluid flow out completely. During the flushing stage, I ran distilled water through the system twice to prevent residual impurities from clogging the pipes. I bought the green-type antifreeze recommended by Kia and checked the manual for the correct mixing ratio. When pouring it into the expansion tank, I made sure not to overfill it. After starting the car and letting it warm up for ten minutes, I patiently topped up the fluid several times during the bleeding process until the bubbles disappeared and the fluid level stabilized. Once I cleaned up the tools and saw the engine running smoothly, the sense of accomplishment was exhilarating—plus, I saved on repair shop fees. Changing the antifreeze every two years effectively protects the engine from corrosion, and reading the manual beforehand is the safest approach.
