Have you looked on the radiator itself?

How to bleed the cooling system.
1.Jack the front of the vehicle up onto stands as high as possible,
2.Turn the ignition on,engine off,heater on fan setting 1 and temperature fully hot,
3.Remove the rad cap/expansion cap,remove the bleed screw from the rad and IF you have them the bleed screw(s) from the thermostat housing/top hose, return pipe or EGR thermostat.
4.Fill the radiator up and keep pouring till there are no more air bubbles coming out from the bleeds, when good then install bleeds and tighten down(don't snap them),ensure the rubber O-rings/seals are still on the screws/on the bleed holes.
5.Suck some water out so it's not full to the brim, replace the cap and then start the car. Run her up and check for heat from the vents when warm and check if over heating still persists.
6.If good then check the water level again in the morning when cool.

No bleeding needed. There are no bleed screws.

drain and fill coolant with fan switched on, heat on full.

fill to max on expansion tank, fire the car up, let run to temp, let thermostat kick in.

Switch off, let cool down......top up if needed.

The E36 M3's are simple as that unlike other beemers that can be a nightmare.
