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
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.

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.
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.
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.
The thermostat regulates coolant flow through the radiator by opening and closing based on the engine temperature. When the engine is cold, the thermostat remains closed to allow it to warm up quickly. As the engine heats up, the thermostat opens to allow coolant to flow through the radiator and dissipate the heat.
The wax or gas element inside the thermostat expands in response to the increasing engine temperature, causing the thermostat to open and allow coolant flow to regulate the engine temperature.
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.
A thermostat bypass on an engine allows coolant to flow around the thermostat when the engine is cold, helping it reach operating temperature more quickly. This bypass ensures that the engine warms up efficiently by allowing some coolant to circulate even when the thermostat is closed. Once the engine reaches the designated temperature, the thermostat opens, allowing coolant to flow through the radiator for cooling. This system helps maintain optimal engine performance and efficiency.
The normal direction of circulation in the coolant system would push the coolant out the thermostat opening.
That would be the thermostat.
No, the thermostat and the coolant bypass solenoid serve different functions in a vehicle's cooling system. The thermostat regulates the flow of coolant to maintain the engine's optimal operating temperature, while the coolant bypass solenoid controls the flow of coolant around the engine when it is cold. They work together but are not interchangeable components.
