Hello,

the coolant temperature sensor is located in the engine block by the radiator hose outlet. Here is a guide and a couple of diagrams that shows on both engine for that car. (BELOW)

Hello –

Should be located on the left front of the engine block, near the alternator – look for a black and yellow wire to the plug.
