Hose size for aux temp gauge sensor
As the Z4M does not have a water temp gauge as standard it has an oil temp in stead, If I was to fit a water gauge where would be the best place to put the temp sensor.
I am going to put an adaptor hose/pipe in the hose that comes of the thermostat housing to put the sensor in.
Can anyone tell me what the internal diameter of the hose is item number 1 in the drawing?

Water temp gauge
I'm sure there is a app you can use to read water temp on your phone whenever you need to. Via the OBD port.
The one I have (Autometer) is shite tho so don't buy that one.

I use one of these, I attached it to the dash with some double sided velcro, prefer a digital speedo in my old age.

36mm will be perfect for the adaptor.

There's a reason oil temp is measured on the M and it's because it is the only important temp. As long as your oil temps are correct why would you need water temps? Unless you just want to add gadgets?

If placed after the thermostat you can see when or if it opens and you would see problems with the water coolant system, although the ECU should send some warning lights on, on the dash.
The ECU connected one looks like it could be before the stat as it is in the water rail at the rear of the water pump (could be wrong)
The oil temp is standard and a good reason as it is very important, but having water temp is also a good to have and surprised it is not standard on the M

The Mk3 VW Golf in the 90s had a coolant level sensor, meaning that the car could alert you if your coolant was running low (e.g. your coolant system had sprung a leak). Most cars provide a low coolant level warning function, but these BMWs don't (edit: I have since been told that they do ) . More to the point, they have a long-running history of using expansion tanks that crack and pee all your coolant out. Even without the poor expansion tank performance, coolant temperature is most definitely an important piece of information to be armed with. On a previous car of mine that was a little more highly-strung, before I had even completed the engine conversion I had installed gauges to monitor boost pressure, oil temperature and oil pressure to complement the factory coolant temp gauge. Why wouldn't you want early warning signs that you might be about to cause damage?a340driver wrote: ↑Wed Jan 29, 2020 9:24 pm There's a reason oil temp is measured on the M and it's because it is the only important temp.

Water temp is as important as oil temp, imho probably even more so as you can see straight away if there is an issue with your cooling. Oil temp will take much longer to show any deviation. These things are not ECAM driven.a340driver wrote: ↑Wed Jan 29, 2020 9:24 pm There's a reason oil temp is measured on the M and it's because it is the only important temp.

Don’t disagree re. water temps being important but they do have coolant warnings. There’s a level sensor at the bottom of the expansion tank and temp sensors in the hoses (13 and 15, above).wonkydonkey wrote: ↑Wed Jan 29, 2020 10:24 pmThe Mk3 VW Golf in the 90s had a coolant level sensor, meaning that the car could alert you if your coolant was running low (e.g. your coolant system had sprung a leak).

Ah really? This is a huge relief then, thanks! I'm glad I haven't found that out for myself yet, also

Most warning lights that come up on the dash just tell you it has gone or failed, if that is oil pressure then if it has gone it’s game over for the bits in the engine that need lubrication, a gauge may give you time to turn it off and save the engine.
