Somewhere by the back of the engine please help

 

could be leaking at the enging coolent temp sensor. or the coolant hose buy the oil filter check the clamp it might be missing

 

not by the oil filter
more by the back of the engine is that the coolant temp sensor
i thought it was in the lower radiator hose but is that it on the back of the engine
any experts on this?

 

that is where the temp sensor is located in between the engine and the fire wall

 

will i need a new sensor?
Does it clip inor unscrew?
If it screws in and it's leaking there, I can remove it and put nylon tape/pipe dope on the threads and put it back in, right?
Should stop the leak...is it possible or common that they leak there?

If they don't screw in, I need a new sensor and oring, correct?

 

bump

 

probably the heater core hose
gotta get a mirror to see in there better
need more brake cleaner too.

 

Is a heater core and hoses a biathc to replace diy?

 

The leak from the temp sensor was traveling down the heater core hose.
Ok, well I got to the dealership and got an o-ring and new clip for the temp sensor.
The old o-ring was mush. Put the new one in and checked for more leaks.
Thankfully it was not the heater core.

 

The Coolant Temperature Sensor fails quite often and a lot of people have leaks around it. There was actually a recall for 2001 and up (i forget to what year) if you were under 100k miles. (I don't know if your car is a 2001 or not..but yea..)

Coolant Temperature Sensor..$20 for the sensor
Heater Core..a lonnnnnnng and annoyingDIY or $1000+ from the dealer. Youre lucky...
