1990 300SE specs needed to replace head
I am putting the head back on my 1990 300 SE and I want to know in what order do the bolts get tightened down and to what torque pressure

My w123 runs at normal temperatures in day to day driving about town and on the freeway. However, when driving up through the Sierras recently, the gauge climbed steadily to near the red. The temperature decreased on the decents.
Before I drive up to the mountains again in about a month how can I troubleshoot the problem?
How does the little air vent, mounted top center dash, sample the interior cabin air temperature? What does the tube connect to? Does it draw air in by the means of pump or just passively? My heat just doesn't want to stay constant and I have replaced monovalve, thermostat, etc. Thanks for anything anyone has to offer.
Hi I replaced front wheel bearings and races as a set, used good quality parts. when trying to preload the bearings as stated in manual The nut tightened untill there was no more thread but the wheel still moved very freely. There did't seem to be any play. but it doesn't seem right. is there supposed to be a flat washer between the nut and outer bearing. There wasn't one but I remember seeing this on other cars
I overhauled the turbo using the mercedessource kit.
Had the turbo and compressor balanced.
Need advice on turbo compressor nut torque techniques.
I used the kit recommendation:
Nut touch the compression wheel, turn CW about 90 degrees using supplied 3/8 wrench and stopped when I judged force to be adequate. Balance marks aligned.
Turbo whine is noticeable when cold engine. Much less so when operating engine temp.
I judge to be a nut torque issue.
