If the coolant temperature rises above the limit, there may be a circulation problem caused by a malfunctioning pump. You can quickly check this by disconnecting the return hose from the radiator header tank and seeing if liquid comes out. If no liquid flows from the hose, first check for blockages in the hose and the thermostat valve.

If everything is clear, the problem is likely with the water pump, as you will find the plastic impeller broken when you remove it.

How to Reset the Tire Pressure Light on a MG ZS?

On the instrument cluster of the MG ZS, the tire pressure light that appears can be reset by inflating the tires to the correct pressure: this value will be indicated on the sticker attached to the driver's door pillar. Once the tires have been properly inflated, you can turn on the instrument cluster and navigate through the menu until you find the option that indicates tire pressure: if this screen shows the new values, the light will turn off; otherwise, you will need to drive for a few miles so that the sensors can read the new values and turn off the light afterward.
