This adjustment is carried out on a cold engine. A suitable temperature is approximately 20°C/68°F. 

At a higher temperature, for example with a warm engine or a higher ambient temperature, the needle is further to the right.

The illustration shows the position of the indicator when aligning the timing belt tensioner at different temperatures.
