What causes car to overheat going uphill?

Studies have shown that coolant is the basic item that your engine’s cooling system needs to flow and get rid of heat from its compartment. Low coolant level is a first sign of a blown head gasket.
Why do cars overheat at high altitude?
When driving at high altitudes, remember the following: Thin mountain air can affect your car’s engine and diminish your acceleration and climbing power. The potential for overheating is greater. The potential for vapor locks is greater.

At altitude the air is a lot thinner than at sea level, meaning that oxygeen levels are less, so your car may run a lot leaner, may cough and splutter a bit due to the reduced oxygen available. The engine may run a bit cooler at altitude, as the higher up you go the cooler the teperature gets.
How much HP do you lose per 1000 feet?
As a general rule, a naturally aspirated combustion engine will lose 3% of its power for every 1,000 ft of elevation gain. If you have 100 horsepower at sea level by the time you get to 5,000 feet of elevation your engine is making 85 horsepower. At 10,000 feet of elevation your engine will make 70 horsepower.
Why does my car not cool under an incline?
You may have an air bubble in the system that causes the thermosensor to not be immersed in coolant when you’re under an incline. An airbubble is never good because it means that the car cannot efficiently cool itself but in this cause it is even worse because it actually causes the fans to not come on.
Why is my radiator overheating while going uphill?
