Why is my car engine so hot in the summer?
Due to the process where in hot weather causes fuel to evaporate faster, gasoline refiners sometimes alter from a higher hot blooded fuel to a lower one when summer approaches. The fuel could evaporate too much that it would create too much vapor and would eventually inflict the engine.
Why is a cold engine hard to start?
This causes the fuel to be more burdensome to burn due to the fact that it is burnt when it is evaporated. This is another reason why cold engines are hard to start. Like any other fluids, oil alters its characteristics when it is heated or when it is in a very hot weather.
What to do when a hot engine is hard to start?
Although usually engines exposed to cold weather is the most known problem related to car starting difficulties, hot engines might bring obstacles as well. Many people realize that the car does not start as easily as it should when the engine is hot and do not know what to do about it.
What causes fuel pressure to drop on a warm start?
The pintles can wear out and allow fuel to bleed off into the cylinder thus dropping pressure. This excess fuel in the cylinder can cause a flooding condition on warm start which the PCM doesn’t know how to deal with since it expects fuel pressure to be there and thus won’t immediately demand anything from the fuel pump.
What happens to a car engine in cold weather?
And he says that idling your machine in the cold only leads to a shorter lifespan for your engine. In older car models that relied on carburetors to run, frigid weather did pose a threat to engine performance.
How long does it take for car engine to warm up?

What happens when engine heats up to operating temp?
As the engine heats up the ring-cylinder mate becomes looser so that the engine will run smoother and easier…but if there is too much wear the combustion gases will begin to blow by the ring-cylinder surfaces and will cause each stroke to lose power.
