What did you do for your M3 today?

Ugh, I kind of suspected that when I removed the original fan clutch and it didn't spin freely or easily, just like when I assembled the new one. Ok, I'll continue to search for the real problem. Thanks!

ah man too bad it wasn't a quick fix with the fan clutch. I would look at the radiator, make sure any debris is cleared out like mentioned earlier. Do you know if the radiator is the original unit?

As far as oil temps those look fine for high ambient temps. Yesterday the ambient temps the car was reporting was 100+ in traffic in the highway my oil temps would move smidge to right of center, but coolant temps was 1/2 mark.

Hopefully, it is something other than the thermostat and water temp sensor, because both of those were replaced a couple of weeks ago when it was in the shop for running warm and VANOS replacement. They told me when I picked it up, that during their test drive after the work, they suspected the fan clutch may be going bad. That's why I did the fan clutch replacement.
Thanks. I'll keep looking!

Which temp sensor, upper or lower? And does it still have the original rad?

Whoa, Hot! yer i would be investigating the new clutch fan is working properly or the cooling system is failing, maybe the thermostat ??

No there is something else wrong, should be dead center during street use.

Well, the weather cooperated and I finally got around to checking out the new fan clutch to see if it made any difference. As you can see, the car said it was 98F outside, the oil temp was good and centered on 210F, the engine temp was up a bit past midway with the A/C running. I had just come to a stop at a stoplight when I grabbed the phone and took this shot. Does that engine temp seem "normal" for a hot day like today? The engine coolant temp gauge did come back down towards the center point after I was moving again. So, I'm thinking that things are better now, when compared to the old fan clutch. Before I installed the new one, the temp gauge went past the right/last white dot, closer to the red zone and it the ambient air temp wasn't as hot as it was today. Your thoughts are appreciated! Thanks!
