Still overheating disco2

Well I drained the radiator the only way I knew how, or could.
I have been driving the car locally for 3 days and the temperature guage has not moved from 'normal'.
The problem is that the coolant level in the expansion tank is inching slowly downwards.
I have the car booked in at Biggs Eastside for a coolant pressue check. They will also change the oil and visually check for any coolant residue in the old oil.
Thanks.

Update: Biggs Eastside said they drian the coolant via a plug next to the water pump, facing the radiator.

Update from Biggs Eastside:
The Check Engine light = This is due to the ill fitting fuel filler cap - evaporation issue, so they filed the cap screw thread down. I have to monitor it (the clicking when replacing the fuel cap is just the top 'spinning'.)
Oil = no sign of coolant in engine oil.
Throttle Body Sensor = shows signs of seepage (not leaking) so it is NOT an issue.
The squeaky Serpetine Belt = Coolant leak (onto the belt) from front timing chain cover. Fix is to replace gasget for $500.
And..
Main reason for coolant leak = Head gasget needs to be replaced for $2300. (Generic problem on engines with 60K to 100k miles.)
Many people have the coolant leakage and carry on by just topping up the expansion tank every week.
I purchased the car 1 month ago for $9000. I am undecided about what to do next, and will weigh up the pro's and cons.
I hope this post helps some people.
P.S.
The original overheating was due to the coolant level dipping too low. What happens is an air bubble gets in and circulates getting bigger due to the heat!
So your pushing a bit of air around the block that has no cooling properties. Makes sense to me :-)

The gasket is a low priced item (like $20), but here is the factory list of what to do to renew it, all labor. Head gaskets are higher, you'll want a set with new head bolts as well (around $300). Both these are things that can be a DIY project for the serious owner. If going the open checkbook route, shop around.
Please resist the temptation to pour in three bottles of head gasket "fix" - that is something you would have to weigh carefully. Under certain conditions things will become worse. But if you are lucky the need to repair could be extended for some period of time.
