How to Solve the Blue Temperature Gauge Display on MG ZS?

[LouisAnn]

When the temperature gauge on the MG ZS displays blue, it indicates that the engine coolant temperature is below the normal operating temperature. This is a normal phenomenon and will automatically disappear once the engine warms up. The hazards of an excessively cold engine are as follows: 1. The temperature of the air-fuel mixture (or air) entering the cylinders is too low, resulting in poor combustible mixture quality, making ignition difficult or combustion delayed, leading to reduced engine power and increased fuel consumption. 2. Water vapor in the combustion byproducts tends to condense and form acids when combined with acidic gases, accelerating corrosion of engine components and parts. 3. Unvaporized fuel washes away and dilutes the oil film on part surfaces (cylinder walls, pistons, piston rings), intensifying component wear.
