just replaced thermastat-- car now runs hot
So I thought I'd put a new thermistat in my 2000DII, since it still had the original.....I'm NOT a DYI guy, but I thought what the hell.... it was really quite easy to install.... noticed quite a bit of antifreeze came out ...so I topped off with some distilled H2o and antifreeze... with a bottle of water wetter added, also( I put all this in the overflow tank). I went to drive it... and noticed that the temp started creeping past the middle( its NEVER done this), and the fans were running... I immediatly turned around and came home--1 1/2 blocks... shut the car off ... it never got to more than 75% of the top..... but why would my car start to run warm AFTER i changed the thermistat... I connected the hoses to the right places.... should I have done something else?... thanks in advance to my "Newbie"post

You put the thermostat in backwards. Check the rave to make sure you have the direction correct. The angled side goes to the passenger side.

Did you bleed(or purge of air)the cooling system after you replaced the thermostat? If not you probably have an air pocket in the cooling system which will prevent the coolant from circulating (air compresses, liquid doesn't). It means your coolant pump will be turning but the coolant won't circulate.

There are several ways to bleed the system, just do a search and you will find what you need. Personally, I take the cap off, raise the coolant tank above the bleed screw, and then loosen the bleed screw and wait for coolant to come out. Tighten the bleed screw, put on the cap and secure the coolant tank. I have to do this a few times before all the air is out.
WARNING: you said your bleed screw is in the middle of your top hose. The new style hoses have it at the junction. BE CAREFUL LOOSENING AND TIGHTENING THAT SCREW! When tightening it, do not tighten too much or it will break and you will be pissed because you have to order it or pick one up at the BMW dealer. LR doesnt sell just the bleed screw.
