I have a Kia Optima 2002. I needed to replace the coolant temp. sensor. Where on a diagram, of the motor, v6, will I locate the sensor?


Depending on what car/ model you have, there may be 2 sensors on the engine. I don't honestly know about your particular vehicle.

However, you needn't rely on a wiring diagram to find it as they are very easily located.
Below is an image of a coolant sensor temperature. Yours will look pretty much like the one in the photo.
25929734-llkdp3pjxd1sy1nazmdezhqo-2-0.jpg To find it, open the bonnet/hood of your car and look at the cooling system. Somewhere, in the area of the thermostat (there'll probably be a wide-bore water hose in the vicinity) you'll find it. It screws into the metal of the thermostat/cylinder head area, and connects via that black connector to a connector on the wiring harness. It should be quite easy to see.

The job of the coolant temperature sensor is to work in conjunction with other sensors, to control the fuel/air mixture combined with engine temperature.

Often, on vehicles such as the Jeep Grand Cherokee (which I have) an error message may appear on your display to say 'coolant temperature sensor bad'. In the case of the Jeep Grand Cherokee this is a known 'bug' - there's nothing actually wrong with the sensor. The Jeep runs fine ..it's a 'false error message'. An occasional bug.

Is your Kia running fine..? If it's not overheating and doesn't have starting/idling/running problems...

Location of engine coolant temperature sensor


Automobiles: 2000 Ford Escort ZX2 4-cylinder 2.0L MFI DOHC

NOTE
The "left" side of the engine is the driver's side.

The Engine Coolant Temperature (ECT) sensor is a thermistor (a device which changes resistance or voltage as temperature changes). The sensor detects the temperature of engine coolant and provides a corresponding signal to the PCM (Powertrain Control Module - aka "the car's computer").

The ECT sensor is mounted in the following locations (small Ford engines):

1.8L engines: in the cylinder head
1.9L engines: threaded into the heater hose inlet pipe
2.0L engines: at the left rear of the engine

2.0L Zetec Engine

(1) Partially drain the engine cooling system using a clean container. If coolant is in good condition, retain for reuse.
(2) Disconnect the battery ground cable.
(3) Disconnect the electrical wiring connector from the engine coolant temperature (ECT) sensor.
(4) Remove the retaining clip and the ECT sensor.


12_5_2011_5_38_05_pm.jpg

Fig. 1 Escort ZX2 ECT sensor - The retaining clip is removed (at the solid arrow). Withdraw ECT sensor by gently wiggling/pulling in the direction of the dashed arrow.

To install:

NOTE
Coat the ECT sensor O-ring with clean coolant prior to installation.

(1) Replace the retaining clip and the ECT sensor.
(2) Connect the electrical wiring connector from the Engine Coolant Temperature (ECT) sensor.
(3) Connect the battery ground cable.
(4) Refill the engine cooling system. An inexpensive plastic "Radiator Funnel" will help with this task.

Could you tell me where the coolant temperature sensor is located at on an inline 6, 4.0L 2003 Jeep Grand Cherokee Laredo?


zjlimited_1234.jpg

Fig. The coolant temperature sensor is installed in the thermostat housing (click image for zoom).
  1. Partially drain cooling system until coolant level is below cylinder head.
  2. Disconnect coolant temperature sensor wire connector.
  3. Remove sensor from thermostat housing.
Hope helps (remember to rate ths answer).

Coolant level low light comes on and coolant level is not low in reserve tank or radiator.


There is a TSB for this problem. Here it is.


Bulletin No.: 04-06-02-007

Date: August 11, 2004

TECHNICAL

Subject:
Low Engine Coolant Level Indicator Always On (Diagnose Low Coolant Level System Operation/Check Sensor for Oil Contamination)

Models:
2000-2002 Buick Century, Regal
2000-2001 Chevrolet Lumina
2000-2002 Chevrolet Impala, Monte Carlo
2000-2002 Pontiac Grand Prix
2000-2002 Oldsmobile Intrigue


Condition

Some customers may comment that the low engine coolant level indicator is always illuminated.


Cause

The cause of this condition may be due to engine oil contaminating the coolant. Possible sources of oil contamination are internal engine leaks, improper service procedures, or the addition of some types of anti-leak additives to the cooling system. Once in the coolant, the oil leaves deposits on the level sensor creating an insulating film. This film results in a false activation of the coolant level indicator.


Correction

Diagnose low coolant level system operation and check the sensor for oil contamination using the procedure listed below.


Important: No coolant supplements should be used in GM cooling systems, other than what is approved and recommended by GM. The use of "aftermarket" over-the-counter sealing and cooling supplements may affect the operation of the low coolant level sensor. Discoloration of the coolant recovery bottle is normal and does not necessarily indicate that coolant contamination is present. Flush cooling system only when instructed by this bulletin.

1. Verify that the coolant is at proper level in the radiator and the coolant recovery bottle. If the coolant is low, add proper amount of 50/50 water and DEX-COOL(R) mixture. If the low coolant light operates properly, diagnose the cooling system for loss of coolant as outlined in SI. DO NOT proceed further with this bulletin.

2. Remove the low coolant level sensor. Refer to Coolant Level Module Replacement in the Engine Cooling sub-section.

3. With the key on, the engine off and the coolant level sensor disconnected from the vehicle wiring harness, observe the low coolant light:


^ Light is on - Chassis wiring or instrument cluster concern. Follow the appropriate diagnostic information in SI.

^ Light is out - Proceed to Step 4.



4. With the key off, connect the coolant level sensor into the vehicle's wiring harness. Connect a ground wire (1) to the battery negative terminal. Using a sharp probe (3) attached to the ground wire, ground the coolant sensor probe (2) as shown in the illustration. Make sure a good contact is made. With the key on and the engine off, observe the low coolant light for at least 15 seconds.


^ Light is on - Replace the low coolant sensor and re-check system operation.

^ Light is out - Proceed to Step 5.


5. Using a small wire brush or emery cloth, polish the low coolant level sensor probe to remove any film or oxidation. The probe should be a bright brass color when finished. Use Brake Parts Cleaner to flush removed deposits from the low coolant sensor probe. Re-install the low coolant sensor into the vehicle and proceed to Step 6.

6. Flush the cooling system and install new DEX-COOL(R) mixture as outlined in the SI. Check the vehicle's warranty history to determine if any engine gasket had recently been changed. If there has not been a recent gasket replacement, locate and repair the source of the engine oil contamination.

Try and clean the throttle body. Carbon will gum up on the blade and the vaccume passages, which will cause a surge and stall.
