Well i noticed my car running reall cold, not even getting out of the blue on the temp guage. I figured it was my thermostat, so i decided to change it. I pop off the thermostat housing and pull the old thermostat out. Looked normal to me, and it was working properly. The only thing i noticed was the gasket looked a little old, but that shouldn't effect my car that much. I decide to put the new thermostat in for the hell of it, and it wont fit at all. Im thinkin " wrong one?" I call my shop, and verified its the right one. I go back to seeing why it wont fit. After fucking around for about 10 min i decide to consult my friend the Bently. What i found was disturbing. The old thermostat was installed BACKWARDS. Obviously it didn't mess my car up that bad, but the scary thing is i have the records of the car dating back to 1992, and from what I could tell the thermostat had never been changed, and I doubt the car would have had it's thermostat replaced from 1989 to 1992.
Is this a mistake BMW did when they built the car? Or maybe a shadetree mechanic had changed it not knowing. The wierd part is for the life of me i could not get the thermostat to remotly fit trying to put it in backwards. I got the thermostat in, bled the system, and now everything is normal. My heater blows hotter air(like my 87 did) and it seems to run a lot better.
End of story, just felt like sharing.
