Video tutorial

Replacing the coolant is necessary and should be done regularly. It is especially important in winter when temperatures drop.

First, disconnect the upper hose from the coolant header tank. Then, start the car and top up until the liquid flows out. This topping up process should be done after bleeding the engine and disconnecting the battery for safety.

Once the tank is replaced and the hose reattached, remove the caps near the headlamp and the battery, then start the engine. This will allow the vehicle to warm up. Wait for the thermostat to activate and circulate the water.

How to Reset the Tyre Pressure Warning Light on a Kia Rio?

Once all tyres have been inflated to the recommended pressure, turn on the ignition to check that the light has disappeared: if it is still present, it may be necessary to drive for a few miles, allowing the sensors to work and thus turning off the light.
