Hi Guys, recently replaced my thermostat on my Z3 3.0i, one of the bolts sheared. Ressembled with out replacing the offending bolt due to time restrictions.
So yesterday removed radiator (more accessibley) removed the thermostat, about 10mm of thread well and truly stuck in the cylinder head, no amount of wd40 etc had any affect. So borrowed a friends mig welder, tacked a nut on to the stud, applied heat (oxyacetylene) and after 10 mins it moved. How much grief one little bolt can cause. One very happy bunny now. Had dreams about drilling and Heli coils etc!
Hope this helps anyone that might come across this in the future.
