Engine temperature rising when the engine is idling is normal. The car is sitting still and no air is entering the engine compartment. This will cause the engine temperature to rise. The cooling fans then come on and the engine returns to a normal temperature. Unless the cooling fans do not bring the temperature down, you have no problems and this is totally normal.
Check the coolant level. If it's not a problem, then it can be contaminated radiator, bad water pump, check leakage.
because engine cannot circulate the cooling sytem, like a water pump.
Your radiator cooling fan is malfunctioning
A certain amount of the energy carried by the cooling water, is kinetic energy, from the circulation through the cooling system. When the engine is turned off, the water stops circulating. The kinetic energy contained in the water is converted to heat, thus raising the temperature of the coolant.
I presume the engine is running when the car is parked if the temperature guage does not move to the normal position when the car is moving at road speed but goes up when the car is stopped and the engine idling, then more than likely the thermostat is bad and needs to be replaced. If you se that the temperature guage is in the normal position anafter the car has been running a while and the temperature guage then goes down when the car is moving at road speed, then this confirms that the thermosta is bad.
Short answer: The engine is working harder to keep the inside of the car cool, so it heats up.Detailed answer: The temperature of the engine rises due to the extra work. The opposite is true too. If you need to cool down the engine temperature on a hot day, open your windows and turn on the heater to maximum. This will dissipate more of the heat being produced in the engine, especially if you are stuck in slow traffic, where the radiator is not getting sufficient airflow because of the low fan speed when you are idling. If fact running the engine up above idle will help the engine temperature go down in this case.
When temperatures are -53 with the wind chill, it can affect a car. The cold temperature can make the car hard to start, the engine will be slow to warm up, and the rubber on the tires can harden causing the tires to lose grip.
Oxygen and petrol or diesel is burned in a car engine, it is not formed
Yes you do. it is there to speed up the rise in temperature of the engine components to reach optimal operating temperature sooner which prevents damage to the engine.
The thermostat is failing.
the engine gets hotter and that makes the temperature rise and could sometimes break down the car if it is to high
A) It needs to be serviced. B) An animal in your trunk is uneasy when the engine idles.
1994 Chevy suburban....no coolant leaks...but looses coolant is this an older car? does the car loose engine coolant?
your car idles low because it is hard for the engine to run fast. which sounds more comfortable, 1200 RPM, or 8000 RPM? the car isn't moving, and as such it doesn't need the engine to run fast to propel it, so the engine doesn't turn fast.
Bondhi Darman is coming!! Best answer
A signal from the temperature sensor on the engine.
Ask this question again specifying what the car is.
The engine's thermostat controls the engine coolant temperature. The temperature control inside for the heater controls the cabin heat.
My 1990 idles at about 850 and with the ac on 1100
Actually there are many ways to tell if you have a bad cat. .A rotten egg smell coming out of the exaust .Hesitation and/or bucketing when acceleration takes places .Increase in engine running temp .A ratteling in the muffler as car idles .Car dying sparatically due to engine backpressure .Difference in temperature from the back of the converter to the front due to clogging
