E46 running warm?

Ok I'll jump right on the thermostat then... It's been fine today so far

E46 failed thermostat will be in the OPEN position. Easy fix on manual but have to take the fan off on an auto.  Wise to replace water pump while in there. I didn't and  to this day could kick myself.

Keep an eye on temps over the next couple days- it may have been high as a fluke. Or even paper or plastic stuck on the grill and fell off while at work

Trust me I've been keeping an eye on it all the time.

So weeks have gone by and it's only doing I when I let the car sit for over 16 hours so I'm thinking thermostat...

[RamRod E28]

And after sitting it has to be 10 degrees or colder for it to do it

What thermostat do you guys recommend for replacement?

^ what he said. Don't go cheap.

Pelican parts?

Yep, they probably sell a couple different ones. Don't have to get the one that says OEM, choose another mfg that says OEM supplier. Same part without the BMW sticker on the box.
