Hello,

I have just bought this car recently and cannot find the engine coolant temperature sensor on the vehicle.

Is it easy to access?

Yes, there are 7 coolant temperature sensors, the main sensor is located in the block just behind the throttle body. Here are all of the sensor locations and how to change them out. Great question btw. Check out the images (below). Let us know if you need anything else.
