If you had a bad coolant temp sensor would that cause the engine to not heat up well on cold days it takes FOREVER to get to normal or would that be a thermostat or a heater core i am puzzled?

Hello, Jamison here, The first thing, The temp sender or sensor, Have NOTHING to do with the temperature of the motor or the heater.This part only tells you the current condition of the MOTOR. If your heater is not heating up, It is likely either low on water (in the radiator) or The heater core is stopped up,,,,,,,If the engine takes A long time to heat up it is likely either low on water (in the radiator) or your thermostat is stuck open. ---------------------------------------------------- ^^^ The Engine Coolant Temperature Sensor DOES have to do with the Motor. The PCM uses this reading to raise idle rpms, change air/fuel mixtures, or turn the fan on/off if the engine is to hot among other functions. However what the questions describes is most likely a bad thermostat. If a thermostat goes bad it has a fail safe to stay OPEN and thus lead to your extended warm up periods and low engine temperatures. This is an easy DIY operation

What does the thermostat on a car do?
The thermostat in a car regulates the coolant temperature inside the engine. When the engine is cold, the thermostat is closed, allowing the heat from the combustion chamber to heat the fluid (coolant) in the coolant galleys in the engine block. Once the engine reaches an optimal temperature, the thermostat opens, allowing coolant to flow through the radiator. The thermostat then controls the flow of coolant to hold the engine at its optimum operating temperature, irrespective of engine load and operating condtions.

Where is the heater core temperature thermostat?
The temperature of the coolant entering the heater core is controlled by the engine thermostat. The engine coolant thermostat is generally located at the engine end of the upper radiator hose.
Why does the engine temp go down after warming up?
When you start the engine, the thermostat is closed. After the coolant warms up the thermostat begins to open up allowing coolant to flow thru the raditor. When first started the temp will go a little past what the thermostat is set to open at. After the water begins to flow thru the radiator, the temp will fall to whatever the thermostat is set at. The thermostat holds the coolant in the engine until it warms up. As soon as the engine is warm, the thermostat opens allowing cold coolant outside the engine to mix with warm coolant. The temp drops, the thermostat closes again, until all the coolant is warm.
Engine Coolant Temperature Sensor?
The engine coolant temperature sensor is usually on the front of the engine. The coolant temperature sensor will be in the vicinity of the thermostat housing.
Does the thermostat control the heat in your car?
No, the thermostat controls the temperature of the engine coolant. As long as the coolant temperature is below the thermostat set-point, the thermostat remains closed. Once the temperature arrives at the set-point, the thermostat starts to open, sending heated coolant through the radiator. The radiator then cools the heated engine coolant and the water pump forces the coolant back through the engine. The heater control valve allows more or less of the engine coolant through the heater core. Since the coolant should be very near the set-point temperature of the thermostat, you should be getting hot water through the heater core to warm the inside of the vehicle. The engine coolant is there to keep the engine from melting down or from breaking metal parts and burnng off the oil. It just happens that the heated coolant is useful to warm the inside of the vehicle.
Where does the coolant come out of the engine?
The normal direction of circulation in the coolant system would push the coolant out the thermostat opening.
What component regulates the temperature of the coolant in the engine?
That would be the thermostat.
What happens when you put coolant into a Malibu without running the car?
When the car is cold the thermostat is closed. When the thermostat is closed the coolant does not circulate or get in to the engine block.
Is thermostat important in a car?
Yes, it controls the coolant flow around the engine block, without coolant the engine would overheat.
What does a trucks thermostat do?
when your coolant in your engine gets a certain temperature,usually 180 degrees,your thermostat opens and your coolant circulates through your radiator and it keeps your engine cool so it wont overheat.
What does a car thermostat do?
The thermostat is a device which blocks the flow of coolant through the radiator until the coolant inside the engine reaches a certain temperature, at which point the thermostat gradually opens to allow enough coolant though to maintain the engine at its optimum operating temperature. The thermostat then controls the flow of coolant to keep the engine at that temperature irrespective of engine load and operating conditions. Without a thermostat and engine warms up more slowly and will never reach its optimum temperature. This causes increased fuel consumption and increased wear on the moving parts.
