i'm having overheating problems on my 2ltr 16v scorpio. the temperature gauge only ever goes half way and the first indication is steam coming from under the bonnet. also i have never seen the cooling fans working.

Had this today mate myself mate   Turned out to be a ripped hose. Check to see whether you have pressure in the top pipes, check for leaks/rips and thermostat. To test the fans run the engine revs manualy from the bay for a min or so, as soon as it reaches a certain temp, they should come on. It should also kick in when you switch on the AC. See my other thread.

May not be overheating if gauge is in normal position and fans not running. Could just be leaking a small amount of coolant onto the engine or exhaust and it is this causing the steam. My hose from the bottom of the expansion tank had split at the worm clip and was dripping a small amount of coolant onto the engine causing mine to steam slightly when stopped...

sounds like head gasket to me, had that on my old mk3 2.0 litre.take off the cap and see if the water flows through the header tank.

Trogg,
I had this exact same problem a few weeks ago, *touch wood* has been completely cured by a new reservoir tank cap.
Cheers

Does the heating work okay. A blocked or restricted heater matrix can cause a pressure build up which can blow water out of the overflow. Also if the heater matrix is leaking (maybe so slight that it doesn't notice) then an air lock can form which can make it's way to the overflow pipe & dispel some water in front of it.

When you see steam coming from under the bonnet, have you seen where it is coming from?

Try letting the engine idle with the cap off - do this from cold so that it warms up completely until the fans cut in. The water level will rise, but provided it wasn't overfilled in the first place it should not overflow out the tank. If it does and bubbles violently then it's probably got air trapped in it or possible head gasket fault.
As far as I'm aware, overflow pipes are not fitted onto Ford expansion tanks featuring screw-on plastic caps. The older type with the metal bayonet type fitting do have though and in this case I would suspect that the cap is the wrong pressure rating or not sealing against the lip in the filler neck.

If we're speaking of the same thing, you're mistaken 
I have a 1995 2.0 16v with a semi-transparent plastic tank with a plastic screw-on cap, and it DOES have a rubber overflow pipe running from the top of the tank and down next to the engine, ending up in free air.
When I blew my head gasket, I noticed a heavy blast of oil-filled water coming out this pipe, leaving a dirty pool of coolant on the ground.

Okay, my mistake. As I said, I've only seen the overflow pipes on the old tanks with metal caps...
