How to lower the low coolant level sensor?
1. Park the vehicle on a level surface, shut down the engine and set the parking brakes. Chock the tires. 2. Drain the coolant from the cooling system enough to get it below the level of the low coolant level sensor. 3. Disconnect the batteries. 4. Disconnect the wire harness from the sensor. 5. Remove the sensor from the surge tank. See Fig. 1. 6.
How many ohms should a coolant temperature sensor have?
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. Simply so, how do you know if your coolant temp sensor is bad?
What to do if your coolant sensor overheats?
Poor Mileage. Check Engine Light Activates. Black Smoke from the Exhaust pipe. Engine Overheats. Poor Idling. Do not Use Tap Water to Refill Radiator. Fix Oil Leaks and Gasket Immediately. Check for Coolant Leaks. Secondly, how do you test a coolant sensor?
How to test and replace a fuel level sensor?
How to test and replace a fuel level sensor. Because it’s an in-tank fuel pump, the hardest job is removing the fuel pump from the vehicle. Doing this test can help you pinpoint why the fuel gauge is not working. If this sensor is indeed working on your vehicle, then check the fuel gauge itself. This specific vehicle is a 2010 Subaru Impreza.
How do you replace a coolant level sensor?
Step 7: Remove the electrical wire attached to the sensor. Once you locate the coolant level sensor, you need to remove the electrical wire that is attached to the sensor. The electrical connection may have a nylon snap connector attached to the bottom of the sensor. Remove this clip and then remove the electrical wire from the sensor.
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. Simply so, how do you know if your coolant temp sensor is bad?
Can a low coolant sensor cause an engine to overheat?
On the opposite side of the coin, if your radiator is actually low on coolant and the light does not come on, this can cause the engine to overheat. The coolant level sensor is supposed to be a warning indicator that reduces the potential of this occurring.
Why does my radiator coolant sensor need to be replaced?
However, if the light stays on for an extended period of time, the coolant level sensor or the electrical connection to the sensor may be damaged, dirty, or need to be replaced. On the opposite side of the coin, if your radiator is actually low on coolant and the light does not come on, this can cause the engine to overheat.

Remove the sensor from the surge tank. See Fig. 1. 6.
How to install an engine coolant temperature sensor?
Install the sensor by inserting it back into the coolant access port and reinstalling the clip. After the sensor has been successfully tightened, reattach the wiring harness. Once the sensor installation is complete, install any other parts you had to disassemble (Reverse Of Step-3).
What should I do if my coolant sensor is leaking?
If the sensor uses threads; apply a small amount of (sensor safe) thread sealer to help stop coolant leaks. Note: Some sensors have sealer already applied. Check your manual for proper torque specs. Do not over tighten the sensor or you will crack the porcelain and damage it.
