http://www.xoutpost.com/members/tacairlift.html Some how I missed the removal of the fourth bolt in the directions the first five times I read through them. Thank you very much for sending me these directions, I am confident I can replace the thermostat in about an hour. I have replaced the water pump and thermostat on a 328iC and this looks so much easier. You have saved me over a $1000.00.
