Most cars will not run hot if the radiator is a little low. It sounds like you may have a pin hole in your heater core (coil) and the stem could be coming through your vents. This should have some smell to it. Most cars will not run hot if the radiator is a little low.

Air conditioner or defroster on - normal should be running Vehicle low on coolant? Trying to keep engine in normal range Defective coolant sensor?
No , that's not normal You either have an external leak or an internal leak in the engine cooling system
It could be a stuck thermostat. If the thermostat is not opening fully it will not allow the coolant to move freely through the engine, making it run hotter than normal.
Sometimes you can hear the antifreeze/coolant flowing back through the hoses from the heater coil when you shut off the car. This usually lasts only a couple of seconds. My truck does it when I run the heat in the winter. When you are running the heat in the winter you are sending antifreeze/coolant through a "heater coil" that disperses the heat from the fluid through coils which a fan blows into your car. Since the system is pressurized when the engine is running, it returns to normal when you shut off the engine sending fluid back to it's normal level.
If your engine fan turns on when the engine is not running it is because the engine's coolant temperature is above the factory preset level at which the computer turns on the fan or fans to cool the engine back to normal.
The normal direction of circulation in the coolant system would push the coolant out the thermostat opening.
coolant only flows through top hose when engine is at normal operating temp.. so u have the wrong thermostat, or no coolant in the rad.... Or the water pump has failed and is not pumping the water.
Water pumps are belt driven pumps used to circulate engine coolant (50/50 water and antifreeze) through the engine, around the combustion chambers. Passages direct coolant near the intake and exhaust ports & spark plugs. As the engine reaches normal operating temperature, A thermostat opens and allows coolant to flow through the radiator, cooling the coolant, and then returning back to the engine. Tom
If your engine coolant temperature gauge is indicating that it is running much cooler than normal ( it sounds like the engine cooling thermostat is sticking open / not closing completely ) which means you need to have the thermostat changed. You should consider if have good heat from your heater and if your check engine light comes on.
It is possible a little low on coolant and has an air bubble in the heater core.
Have you noticed your engine temperature gauge running cooler than normal ? A thermostat that is sticking open will make the engine run cooler and cause the P0125 trouble code , also - coolant level low - faulty engine coolant temperature sensor
this sounds like a bad thing to me...like the reservoir and/or the cooling system, has no antifreeze in it and heat from the engine is exiting through the cooling system. Does your temperature gauge read in the normal range? Is the car running OK? FriPilot
this is normal for this engine, in fact anything short will trip a check engine light. the cause will be a low coolant condition, a thermostat stuck in the open position or a bad coolant sensor. this is normal for this engine, in fact anything short will trip a check engine light. the cause will be a low coolant condition, a thermostat stuck in the open position or a bad coolant sensor.
Normal causes are low coolant and an inoperative radiator fan.Normal causes are low coolant and an inoperative radiator fan.
Around 90-100C or 195-210F, if it's running any warmer than that try doing a coolant flush
Most likely you have a leak when the system is pressurized (engine running and at normal operating temperature). A radiator shop will be able to pressure test your coolant system and find the leak. Could also have a cracked engine block, or a hairline crack that expands when the casing gets hot.
After coolant is added run vehicle to normal operating temperature and re-check coolant level
Coolant leak? Check to see if coolant is getting mixed with engine oil Run engine to normal operating temperature and remove oil dipstick, let a drop fall on hot part of engine - oil will smoke coolant will sizzle. If coolant is mixed with oil could be a bad head gasket. If coolant mixes with oil you won't need any special tests to see it. When they mix it will look like a vanilla milk shake. The newer coolant return systems are designed to keep the coolant level inside your radiator and engine full. When you car cools down (after running at normal temperature) it is designed to pull coolant out of the return reservoir back into the radiator. If the system gets too much pressure (usually from getting too hot) it will push coolant into the reservoir and then pull it back in as it cools. If the system has a leak then it will always pull back in more than it pushed out and the reservoir will have all coolant removed. Then the system will begin to draw in air causing the engine to eventually overheat from lack of cooling. Your heater works from the hot coolant passing through a small "radiator" under your dash. If the coolant is low then little or not hot coolant will pass through it.
This is normal (condensation) as long as it is not engine coolant dripping out.
White smoke from tailpipe when engine is at normal operating temperature? Oil mixing with coolant? Coolant mixing with oil? Run engine to normal operating temperature remove dipstick and let a drop fall on hot part of engine - oil will smoke coolant will "sizzle" Misfire at 2 adjacient cylinders?
That is normal operation.
The engine should be at normal running temperature. Make sure to shift slowly through all the gears and return to Park before checking. If you've been driving on the highway or been working the engine excessively, be sure to let the engine cool for about 30 minutes, then return to normal running temperature. -Kevin
when the engine is stopped, the coolant stops flowing. The coolant inside the engine can boil and force coolant into the expansion tank. this is normal.
160 to 185 degrees F is normal running temperature.
If this happens only when engine is cold it is a normal condition If this hasppens when engine is at normal operating temperature it may be a sign of head gasket leakage Check to see if oil is getting into coolant or coolant getting mixed with engine oil
