Hi,
I am looking to drill and tap (M14x1.5) the cylinder at the blank location shown in the picture below to accept E30 Brown temp sender . Before embarking on this I would like advise if this is approach is a good idea or not?
Option 2, can I install the following line with the top radiator hose for installing the E30 temp sender?
Any advice greatly appreciated

You would need to stop swarf going inside when you drill through and then the same when tapping. Next to impossible I would have thought.

on the right hand side of the pic is a hose , take this off it's not needed. then undo the fitting the pipe was attached to and remove it from the head, take this fitting with an e30 brown temp sensor to an engineering firm or an engine builders near you and get them to turn the thread on the sensor down to match the threads on the fitting you removed.

As above, or just send me £25 and I can post you a brand new sensor with the correct thread ready to fit

Thank you for the advice, this what I was thinking of doing after doing some more research on the internet. With regards to removing the hose pipe, this is currently connected to the throttle body, do I not need this or do I just not connect the throttle to the water system?

I have managed to re-grind the existing temp sensor and tapped the correct thread on it (M12x1.5). If I get any issues with I will come back to you to purchase the sensor. Below is the picture of the finished sensor with the correct thread.
