SOURCE: Thermostat location

you didn't mention what size engine you have, so i assumed its a 1.8L. thermostat is located at the housing just above the waterpump on the front of the engine. its #5 in the attached link http://www.realoem.com/bmw/showparts.do?model=CJ11&mospid=48077&btnr=11_1393&hg=11&fg=35

are you sure you need the crankshaft position sensor changed. it is at the back of the engine i believe, but.....
check for a wet ecu first... read the note on e36...

the ecu compartment is under the windshield on the passenger side on E36

you gain acess to it under the hood....
this compartment gets wet, the ecu lays on a flat surface in that
compartment.

the bottom side of the circuit board gets wet and starts corrosion.

remove the ecu, take the bottom plate off, clean the bottom of the circuit
board with alcohol and a soft tooth brush.

you should be able to see the signs of corrosion or conductive build up.

this gunk bridges solder points doing all sort s of wierd things to your
car, including false sensor readings from asc/abs controllers and other
sensors....

all the way to engine failure and worst case burnt and shorted wiring
harness.

I'm on my 3rd ecu, took me and the repair boys a few years to figure this
one out.

BTW: i would get that ecu mounted above that flat surface, use some sort
of standoff to raise it so that it is not laying in the wet.
