Running cold

After driving a bit. Temps were at 88-91c

Sounds right on.

How do you get bluebus to read water temp?

Settings -> UI -> Temps
On non S54 cars you can also get oil temperature


There is also a way to have them all on a line in the display like this but it sometimes just doesn't work for me (C=coolant, A=air, O=oil). I think that might be the Dash. OBC option above:

85C is about where mine sits read via BlueBus from the Ibus (in normal daily driving). Oil temp should be bit higher though once fully up to temp IMO.

Just finish putting after thing back together , here is the temps now.

No, I found the water pump pulley. I contacted tuner Motorsports, and they had the pulley. So when it comes im putting everything back together. Going to flush the coolant system with distilled water.

I had the thermostat and water pump sitting in my garage 3 years so I was like might as well change it now, it also had green coolant so wanted to flush that all out as well. The only pulley that changed on the car was the turner power steering pulley and water pump pulley. The alternator pulley I believe is stock.. I checked on the turner website, but I don't see the water pump pulley by it self. It goes with a lot.

Yeah, to spend all that money for most of what you have seems ridiculous. Did you have switch all pulleys back to stock?

When i get home I'll look at my box. I saved the proper size belt for the Turner Power Pulley Street kit. I believe it is 1535 but I want to be 100% sure before I say for sure. It includes a larger power steering pulley and alternator pulley so just throwing a stock pulley on is a no go unless you make those stock as well. Ultimately I don't think you ever had a failure of your cooling system but you're not worse off with preventing a failure. I'm at my 4 year mark and it almost time to redo the thermostat and water pump. Coolant also has a 4 year service life per BMW.

Highway driving there is a lot of airflow with low load on the engine, so if you have relatively clean fins on your ac condenser and oil cooler, you will see lower temps. I see that on the way to the track. Once on the track with high loads, I see the needle start pegging to the right dot. Normal operation. Enjoy the car.

So I measured the diameter of the water pump pulley, and it reads 5.312inches or about 135mm. Does anyone know the size of the stock pulley? The belt on the car is 6pk1535.

Temp looks normal.

just chiming in, as relatively new owner of my M3 it also leans to the left while cruising on the freeway in cooler temps. Not sure if its a problem as it does fluctuate between the middle and cooler. On the flip side when ambient temps reach 95F and im blasting the AC it moves closer to the 3/4 side, but not quite hitting it.
From my experience on the non-M e46 low coolant temp typically means soft failing thermostat, but the buffer range for coolant temps is a lot bigger than the M, so any fluctuation on the coolant temp on the non-m is more of a concern.

I the only one who doesn't see an issue with the coolant temp? Maybe I haven't driven mine in a long time, but iirc this was pretty normal to run just left of center
