How to replace a coolant temperature sensor on your Radiator?
Once you’re radiator has been drained, make sure to replace your drain plug or reinsert the petcock before proceeding. This will ensure you don’t forget to complete this step before adding more coolant once the coolant temperature sensor has been replaced. Step 7: Remove electronic harness from the temperature sensor.
Why are my radiator fans not turning on?
This is why the fans go on. Normally this means that the wiring and the PCM (which turns on the fans) is functioning. I would suspect a faulty sensor, but it was replaced. There could be a problem in the wiring to the PCM. High resistance or a partially broken wire causing the temp sensor signal to the PCM to be skewed / inaccurate.
Can you change the coolant in a radiator?
Although you may have collected the radiator coolant when you drained it from the radiator, it is highly recommended that you add new coolant. This will ensure that the coolant temperature sensor will work correctly. Add new coolant, mixed with distilled water as recommended by your specific vehicle manufacturer.
What is the job of a radiator fan?
The radiator’s job is to keep the coolant cool so that when it returns back into the engine, it is able to absorb more heat. A radiator fan is thus used to keep the temperature of the coolant in check. Thus, it has an important job.
Why is the coolant sensor on my radiator not working?
There could be a problem in the wiring to the PCM. High resistance or a partially broken wire causing the temp sensor signal to the PCM to be skewed / inaccurate. You need to have a scanner on it to look at what the PCM is showing as the coolant temp.

How much does it cost to replace a coolant temperature sensor?
Unscrew the ECT sensor in an anticlockwise direction, similar to how a spark plug is removed. Install the new sensor and reconnect the connector cable. The average replacement cost of the Coolant Temperature Sensor is between $100 and $220. The labour cost is between $40 and $140 while the part itself costs between $50 and $80.
What’s the name of the coolant temperature sensor?
Coolant temperature sensors are also known as engine coolant temperature sensors or ECT sensors. The principle working of this sensor involves the use of an electrical resistance which measures the temperature of the coolant.
Is there a sensor in the thermostat housing?
The computer doesn’t complain now, the AC will turn on, and the fan runs appropriately instead of continually. The idiot gauge also work and stops right where it always used to, just a notch shy of half the dial. I hope so! I replaced both sensors, the one in the radiator and the one into the thermostat housing.
Can a temperature sensor be replaced on an electric range?
If the temperature sensor fails completely, the control panel on the range displays an error code. Replace the oven temperature sensor using a manufacturer-approved electric range part. Use this procedure to replace the oven temperature sensor in many Kenmore, Frigidaire, Whirlpool, KitchenAid, Maytag, Amana, Electrolux, GE, LG and Samsung ranges.
How do you remove temperature sensor from oven?
Holding the connector with needle-nose pliers, depress the locking tab on the plug and disconnect the plug from the sensor probe. Don’t let the connector slip back through the hole, or you must remove the back panel of the oven to retrieve it. Disconnect the wire plug from the wire connector.
Where is the thermostat sensor on my air conditioner?
The thermostat sensor is located near the evaporator coils. These coils are inside your air conditioner unit. As the air is sucked through the return vents, the air passes by the sensor and the coils. As the air passes the sensor, it reads the temperature and compares…

This will ensure you don’t forget to complete this step before adding more coolant once the coolant temperature sensor has been replaced. Step 7: Remove electronic harness from the temperature sensor.
What happens if the sensor on the thermostat is lower?
It also works in reverse if the air passing the sensor is lower, or at the same temperature set on your thermostat. If this happens, it will shut off the compressor. This is the main function of the thermostat sensor.
How does the thermostat read the temperature of the air?
As the air is sucked through the return vents, the air passes by the sensor and the coils. As the air passes the sensor, it reads the temperature and compares that reading to the setting on your thermostat.
What causes a car coolant sensor to go on?
Heat and engine vibration can cause the sensor to lose its designated resistance which will send a false reading to the computer and may cause the check light to go on. How Much Does it Cost?
How can I check the coolant level in my car?
Step 1: Start the vehicle. Let it warm up to operating temperature. Step 2: Check for leaks. Be sure to check for leaks from the radiator drain plug, petcock, or the coolant temperature sensor. Step 3: Check to see if the check engine or low coolant level light is illuminated.
How much does it cost to replace coolant sensor?
When taking you car into a repair garage or the dealer to have a coolant temperature sensor replaced it will cost between $120.00 and $180.00 (US) depending on the type of car and the location of the sensor.
Step 1: Start the vehicle. Let it warm up to operating temperature. Step 2: Check for leaks. Be sure to check for leaks from the radiator drain plug, petcock, or the coolant temperature sensor. Step 3: Check to see if the check engine or low coolant level light is illuminated.

Can a faulty knock sensor cause a check engine light to come on?
The faulty knock sensor will not cause the Check Engine light to come on nor will it cause the driveability symptoms you describe. The cost for knock sensor replacement is that high because it involves removing the upper and lower intake manifolds for access.
How to replace Waterpump, thermostat and coolant temp sensor?
In this walkthru I show how to replace a waterpump, thermostat and a coolant temp sensor in a jeep grand cherokee. This 3.7L engine is found in many Chrysler Dodge Jeep vehicles such as the Nitro, Liberty, 300 and others. Goodies include a belt routing diagram and how to bleed the air from the coolant. Loading…
Why is a coolant temperature sensor so important?
A coolant temperature sensor is especially important for the optimal performance of your vehicle. While you drive your vehicle, the engine goes through continuous combustion. This can make it very hot during the drive, especially during daytime driving.
Is there a coolant temp sensor on a Mini Cooper?

ACDelco GM Original Equipment Engine Coolant Water Outlets are housings that connect the radiator hoses to the engine, typically housing the engine coolant thermostat. For certain applications, the water outlet contains threaded holes or ports for sensors and switches.
When to replace a car coolant light sensor?
If your car is older, the sensor has deteriorated with time and may be failing but not entirely failed. It is not a bad idea to keep an eye on your sensor’s readings. Replacing a sensor that is starting to show extreme signs of age and wear can prevent future problems.
When does the low coolant level warning light go out?
When you start the engine, the low coolant level light should come on for a second or two and then go out. If it doesn’t go out, either the coolant level is too low or there is a problem with the sensor system.
