Hi there,

To bleed the system follow this procedure....

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.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.

hope this helps,

Thanks for your answer and help.It is an M52 engine 1996. As far I can see there is only one bleedng screw on the rad.

yes this is correct... It should be right next to the filler cap...

Its the same procedure for BMWs with 2 bleed screws... some models have an additional bleed screw in the coolant hose...

Just be careful not to snap it when tightening...it will then become a nightmare..

HTH...
