It seems as if my engine is running 'too cold'... if there is such a thing. When it's cold (in the blue), it idles at about 2000 rpms to warm up. Keep in mind I have an M10 under the hood. In the morning (usually about 40 degrees F) it takes about 15 minutes of driving in order to warm the car up out of the blue on the temp gauge. If I proceed to drive on the freeway after that the radiator cools the engine back down into the blue. I've recently replaced the coolant and the temp sensor. Could this be a problem with my thermostat?

Originally posted by BrewI'd say its almost definitely the thermostat. Its probably stuck open and allowing coolant to flow through the radiator immediately after cold startup.Originally posted by Grueliusand i do not know what bugg brakes are.

As far as coolant spillage goes, at least on the M42, I don't think there's a way to get the thermostat out without draining the coolant first.
Yah it's kind of a hassle, but coolant is really cheap anyway, so you should give the thermostat/coolant change a go.~ Go Canucks Go! ~

As for the coolant drain.. I'd just pluck the housing off and let it drain. Hopefully you wont loose too much. I've found if you drain the radiator a little bit (hoping to lower the level) it only causes twice the coolant to drain out.Old and improved:

I think I remember reading somewhere that as long as the oil temperature is sufficient, the coolant temp can be pretty much anywhere it wants under the 1/2 mark. The only reason your thermostat is there is for heat.
At least I think I remember that right.

i'd bet $10 its the thermostat, same happened when i bought my car... it wouldnt get past 1/4 and it would take forever to get there; a new tstat and i was good to goJay

I had a problem with running at 1/4 ont he gauge with my 90 325i. I took the thermostat out when replacing it wiith a higher temp thermo, and the thing was in two losely connected pieces. How does this happen?!?!
