Hi, I have a new coolant temperature sensor to fit but I don't know where it is located. Can you please help? I'm not a mechanic.

Hello,

The coolant temperature sensor is located on the thermostat housing.
If you open the hood and follow for the radiator hose from the radiator to the engine, you will find the thermostat housing and the coolant temperature sensor is screwed on to that housing.

Since Vauxhall is not sold in the USA, I do not have a diagram with the replacement procedure.
I have attached a picture for your reference.

Please let me know if you have any questions.
Thank you.

The ambient air sensor is located right behind the front grille. Look at the picture below. Its approximately where the red mark is.
