Hard to say. Maybe check your coolant once it cools down.

Yes, but, I would expect the car to COME with one. It's not that crazy.

It's just how BMW is. They must feel oil temp is more important than water temp.

I understand but they should've included both. We HAVE the technology.

Do you get these temps just cruising, or while driving aggressively, traffic jams? I ask because today my engine temp raised to 220-230. Highest I've ever seen. Outside 93. I redlined it two or three times (maybe more) on open highway. I cruised after seen the temp and it lowered fairly quick. I have a Dinan pulley (for several thousand miles now), not sure if this matters that much.

Thanks. I'll be keeping an eye on the temp gauge more frequently.

Anyone know the ratio they use to fill the radiator? 50% antifreeze & 50% Water?

Yes, it appears to be 50:50. Confirm with your manual or dealer.

Mine is usually right in the middle (210) but I have noticed it will sometimes creep past there as well. I live in sofla so it's very hot here and I will usually redline it once or twice during a drive. Is this normal?

Guys I need some feedback....

Remember my original posting about the engine temperature right? Well I notice that the coolant was low so I decided to do a flush (this weekend)

Well....I notice my AC was not cooling well so I took it yesterday to the dealership....They said they have to vacuum the AC and put a dye, drive the car for a while and bring the car back.

The funny part is, they are recommending me to flush the radiator ($200.00)??? Really? my car had low coolant but the engine is not that hot to affect my AC (220~230)....Plus I think is the heater that is linked to the Radiator not the AC...

I'm going to do the Flush in the AC but do you guys think I should do the coolant radiator??? (They said is not just a drain, they are going to clean everything)

While there isn't an analog water temp gauge present, there are still high-temp warnings on the OLED display on the cluster (and iDrive, if equipped).

when the outside temp is 95 is this the only time the engine temp creeps higher?
