Where Is Coolant Sensor Located? Usually, the location of the coolant temperature sensor will be located directly behind the coolant pipe. In most modern cars and vehicles, this is present behind the right cylinder head that is located right underneath of the air intake pipe.
What are the symptoms of a bad coolant temperature sensor? Symptoms of a Bad Coolant Temperature Sensor
How do you change a coolant temperature sensor? Let’s Get Started
Release the Cooling System Pressure. Locate and slowly remove the cooling system pressure cap to relieve the system of any residual pressure.
Locate the Coolant Sensor.
Remove the Electrical Connector.
Remove the Coolant Sensor.
Install the New Coolant Temperature Sensor.
Refill the Cooling System.
How much does it cost to replace a coolant temperature sensor? The average price for an engine temperature sensor replacement is between $150 and $193. Labor costs are between $82 and $105 while parts are between $66 and $88.
Where Is Coolant Sensor Located? – Related Questions
Can you drive with a bad coolant sensor?
It is possible to drive a vehicle with a faulty coolant temperature sensor as the management system defaults to a static reading. A vehicles coolant sensor is a critical component used by the engine management system. It directly effects, cooling and fueling of the engine and therefore effects how the engine performs.
What can a faulty coolant temp sensor do?
If the coolant temperature sensor goes bad it can send a false signal to the computer and throw off the fuel and timing calculations. It is not uncommon for the coolant temperature sensor to fail and send a permanently cold signal to the computer. This will reduce fuel economy, and may hinder engine performance.
How long does it take to replace a coolant sensor?
The actual process of replacing the coolant temperature sensor is extremely simple. However, the difficult work comes in the preparation of the cooling system – both before and after. Tip: This job should only be completed when the engine is cold and has not been running for a minimum of one hour.
When should I replace my coolant temperature sensor?
about 100,000 miles
Often, the engine coolant temperature sensor must be replaced at about 100,000 miles. If you don’t properly maintain the engine cooling system, the sensor could fail much earlier.
How do you fix coolant temperature?
Replacing a Faulty Thermostat
Let the car’s coolant cool for 15 to 20 minutes.
Locate the thermostat.
For better clearance, jack up the front end of the vehicle.
Remove the radiator cap.
Drain the radiator, according to instructions in your car’s repair manual.
Remove the thermostat.

How do you check a coolant temperature sensor?
Connect the black lead of the meter to the body of the cold sensor and the red to the terminal. You should have a reading of approximately 2000 ohms. Check the warm sensor in your engine. You should see a much lower reading on the ohm meter.
Does coolant temp sensor affect AC?
As the ambient temperature sensor plays a direct role in the automated function of the AC system, when it is having a problem this may interfere with the system’s ability to cool the vehicle.
Does the coolant temp sensor control the fan?
The sensor works by measuring the temperature that’s being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on-board control system. As the control system receives the temperature from the CTS, it may trigger the cooling fan to either shut off or turn on.
Can you drive without a temperature sensor?
Most automobile mechanics will tell you it is not a good idea to drive your car without a thermostat installed. If your thermostat becomes stuck in the closed position, though, this will cause your engine to overheat and make driving your car impossible.

Can a bad coolant temp sensor cause hard start?
The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.
Why is my car overheating when the coolant is full?
An engine coolant leak internally or externally reduces the level in the system, preventing proper cooling. Blown head gasket. A blown head gasket can be the cause or the result of car overheating issues. Coolant can leak out, air gets sucked in, and the engine temperature needle wraps around to full hot.
Why is my coolant temperature high?
Lots of things can cause an engine to overheat, such as a loss of coolant due to a leaking hose or radiator, a worn or broken fan belt, a bad water pump or thermostat, or an electrical problem. It can even overheat on a cold day if the coolant is too diluted with water to keep it from freezing.
Why is my coolant temperature low?
Causes of Low Engine Temperatures
Is coolant and antifreeze the same thing?
Engine coolant, also known as antifreeze, is mixed with water to keep the radiator from freezing in extreme cold and overheating in extreme heat.
