Reving it up doesn't really change the temperature if the cooling system is working properly. Depending on the Yr/make/model. Newer cars have higher pressure radiator caps= higher operating temperatures. Mid 90's cars had mainly 180f thermostats with operating temps. up to/around 220f. Newer cars run 220-260*f.
It is not good for your car if you rev your engine too much. Many people like to do this because they think it makes their car sound cool.
I'm going to guess yo have the air on, that would mean that the idle compensator is out of adjustment and over revving the engine.
There is no use for rpm in a car A: I an assuming you mean the rev counter in cars. The rev counter tells the driver how fast the engine is turning its revolution per minute. In a situation where you can't here the noise of the engine, it is useful to see on a gauge how may rev the engine is doing. Max revving a car for prolonged periods can blow the engine.
They rev out to around 9500, give or take a little bit depending on the car
you should never rev your engine when you start your car it sometimes takes the oil pump time to pump oil up into the engine heads if you rev it too much your engine could suck a valve or blow a lifter.
start the engine and press the gas pedal while it is in park
malfunction? Did you turn the car off?
If the engine is hot and the car stops that means it has over heated, it the car is hot in cabin then you may have a problem
how can I get the lowest price on a new car
Rev limiter to save the engine from blowing up. Rev limiter to save the engine from blowing up.
No automobile engine will even run at 2 rpm's. The average engine idles at from 650-750 rpm's, and will easily rev to 5,000 rpm's.
I guess you turn on you car, leave it in neutral, and push on the gas pedal repeatedly.
