Coolant leak

Hi and thanks for using 2CarPros.com.

It is hard for me to tell which sensor you are seeing the leak from. What I suggest is to pressurize the system and then locate where the leak is coming from.

Here is a link that shows how it is done. Take a look at it and let me know if you have any questions. You will need the pump to pressurize the system, but most parts stores will lend you one.

As far as the sensors, I checked in my manual for coolant temperature sensors and they are not located on the front of the engine. Do this test and let me know what you find.

Take care,
Joe

That doesn't sound like fun. Regardless, I'm glad you got it figured out so you can fix it. I figured since you got the job ahead of you, I would add the directions for you in case you needed them. All pictures attached correlate with these directions.
