Install motor temperature clock

As I said I have an Astra 1.7 CDTI year 2004. I tell you what a sneak has for the engine temperature. I would like to know if when there is a margin of being able to save the engine or not (let's fuck the engine). I say it in case it is worth putting a clock for temperature. In case of putting it you know a mark, and because the joke comes out.

Thank you very much and greetings

You have FAE brand temperature clocks with support for about € 50 and are simple to install since they bring a surface sensor (shoe) that are going very well

I would like to know if there is not much problem in passing the engine cables to the habitaculus, and where the clock placement would be better.

Anyway, thank you very much, I will inform myself. ALL THE BEST
