What happens when your coolant temperature sensor is bad?
The engine is very sensitive to wrong air-fuel mixtures at idle and this is a condition when you might notice that something is wrong with your engine coolant temperature sensor. The engine coolant temperature sensor can have a hard impact on the air-fuel mixture. A bad air-fuel mixture can also cause the engine performance to drop drastically.

What should the temp of the coolant be?
The thermostat OPENS at 195F degrees; but, the temperature continues to rise to the normal operating temperature. The temperature of the coolant can rise above 212F degrees because coolant is pressurized (NOT because the water is mixed with antifreeze). Boil-over won’t occur until about 265F degrees, because of the pressurization (15 or 16 psi).

What causes a low coolant level in an engine?
The most common cause of low engine coolant level is external coolant leaks, but it can also disappear from other places. Here is a more detailed list of the most common causes of a low engine coolant level: As we told before, the most common cause of low engine coolant level is external leaks.
Is it dangerous to drive with low coolant levels?
If there is a rise in the temperature gauge check your radiator for coolant levels. You can water until it overflows and continues observing the gauge. If the problems persist, then you are certain of coolant leakage. It is dangerous driving with low engine coolant as it will destroy engine components.
What can happen if I use the wrong type of coolant?
What Can Happen If I Use The Wrong Type Of Coolant? If you don’t use the correct type of coolant within your system, you can experience corrosion and component damage. This damage can lead to long-term effects that will be serious to the overall lifespan of your vehicle.
Why is there coolant in my transmission fluid?
Coolant is used to help control heat but not just engine heat. A vehicles coolant system is commonly employed to also help cool, throttle body’s, alternators, engine oil, turbo chargers and transmissions. A low coolant level may cause any of these components to misbehave.
What causes coolant level to drop when car is running?
Small pinhole leaks in the radiator will cause coolant fluids level to drop. Pinhole leaks may not be noticeable during operation, as the fluid will leak when the car is running under load. But after operation, the radiator will give off a hot moist smell and show signs of leaking underneath.
Is it safe to drive with low engine coolant?
Consequences of low engine coolant. Driving with low engine coolant is never a good thing to do. It can create air bubbles in the system, which in the worst case can damage your engine seriously. Here are a few things that can happen in your engine when you are driving with low coolant.

What happens when there is not enough coolant in the tank?
The transmission is shifting smoothly through all the gears. As the coolant gets lower and lower things will progress as follows: There won’t be coolant in the coolant expansion tank even when the engine is warm. There will often be insufficient fluid to circulate coolant through the heater core and the heat won’t work.

Where is the coolant in the radiator when there is no leak?
There’s a COLD/MIN label on the tank indicating the ideal antifreeze level when the engine is cold. The coolant in the radiator should be just below the filler neck. When you are losing coolant but no leak is visible, several parts could be the guilty party.
What should you do when your car is losing coolant but no leak?
Generally, there should be a leak somewhat if the vehicle is losing a high amount of antifreeze. However, a car could be losing coolant but no leak. What should you do when coolant disappearing from reservoir without leaving any trace?
What does it mean when your coolant level is low?
Your coolant level is low. If the coolant level in your reservoir is very low, below the “Min” or “Low” mark, there’s a decent chance you have a leak somewhere. We’ll get to that in a minute — but there is always the chance that you just need to add more coolant. Solution: This is potentially an easy fix.

What causes low coolant level in radiator surge tank?
The low coolant level in the radiator surge tank may be due to the fill process at the assembly plant, which cannot purge all of the air from the cooling system and the surge tank. After the engine has been thermally cycled, air rises and causes the coolant to become lower than when initially filled. Coolant Levels
What happens to the coolant when the engine gets too hot?
Whenever the engine gets too hot, the coolant is vaporized and passes through a small tube. The overflow reservoir has markings that determine when the coolant has expanded and needs to be expelled. If you suspect that you are running at low engine coolant, check whether the overflow reservoir is above or below the set minimum and maximum points.
What causes coolant to leak from the radiator?
Inside the radiator cap, you will find an overpressure valve caused to open if the pressure rises above a specific pressure. If this valve is faulty, it can happen that this will open before that pressure, and it will cause coolant to leak out. You can often see this by looking for for white smoke coming from the engine bay.
