Can the car start when the water temperature reaches 110 degrees?

The car can start when the water temperature reaches 110 degrees, but it needs to warm up first. An engine that is too cold can damage it. Here is some relevant extended information: Hazards of an engine being too cold: 1. The temperature of the air-fuel mixture (or air) entering the cylinders is too low, resulting in poor-quality combustible mixture, making ignition difficult or combustion delayed, leading to decreased engine power and increased fuel consumption. 2. Water vapor in the combustion byproducts can easily condense into water and combine with acidic gases to form acids, increasing corrosion on the engine body and components. 3. Unvaporized fuel can wash away and dilute the oil film on the surfaces of components (cylinder walls, pistons, piston rings, etc.), accelerating wear on these parts.
