over heating freelander

hi, ihave 98 freelander 2.0l deisel,have airlock in cooling system anybody out there have any idea how i can fix this. thanks

Can we have a bit more info on why you have the airlock. Have you changed the coolant and this is the result?

It seems that purging the system works better if you lift the front of the car first. On the hose entering the bulk head there is a bleed screw. Remove this screw, then top up the expansion tank until only coolant is emitted from this bleed screw. Now fit the screw back in. Get the car back on its wheels and top up the expansion tank to the MAX mark. Take the car for a shhort run and get it up to temperture. On return, check the expansion bottle level. Allow the engine to cool. Top up the coolant as necessary. You may need to do this over several days as the last pockets of air are expelled into the expansion tank.

I hope that helps,

Dave
