SOURCE: location of the coolant temperature sensor

You will find this sensor where the fat hos comes from the radiator and conects to the engine block. It would be on the housing where the thermostat is located. If it is not there you should look for a sensor that has a wire connected to it anywhere on the engine block where a water inlet is located. I hope this helps. Don't forget to rate my answer, thanks.

SOURCE: replacement of coolant temperature sensor

located under intake in water crossover pipe,you can access the sensor by removing intake chamber box,then pcv hose connected to the block,the connector is orangeish 2pin,use a 19mmdeep socket on a 3/8 ratchet to get it loose,make sure engine is cool,also make sure there is a new brass washer with your new sensor,sometimes the old washer comes off when removing the sensor,sometimes it sticks to the pipe,some coolant will escape so make sure to top it off

Follow the hose from the bottom of the radiator to the point where in reaches the engine block. That's where the thermostat is located and the Engine Coolant Temperature switch is there too.

Gs300 coolant is bubbling in resevoir,but temp is fine ?


Get coolant temp sensor checked.

Get the coolant pressure tested, its definitely leaking coolant. You will need to get the coolant running line.


Pressure test will help you to know from where exactly coolant/refrigerant is getting leaked.

My lexus ls400 1991 the two electri fan all time is on


Either the temperature sensor on the radiator, or the relay is bad.
Pull a wire off the temperature sensor on the radiator.
If it stops the fans, then the sensor is bad and the relay ok.

Location of engine coolant temperature sensor


This sensor is a one wire which is normally around t'stat housing. You can start by grounding the wire(s) there one at a time to see if the dash light or gauge comes or move. If it does, that is the sensor wire and sensor should be close by.
