Mine had a leak from the thermostat housing where the connections to the heads and water pump pipe are (left side of the thermostat housing. These are push fit connections, each with two 'O' rings which had hardened with heat and age. Check for a dribble of coolant running down below the thermostat. Took me ages to work out where the leak was.

Mmh sounds like that could be it, I'll have a clean up and keep an eye on it over the weekend.
Is it a hard job to replace? Looks a bit tight down there.

It's fiddly more than anything else and getting the thermostat housing off the connections took a bit of persuading. You need to be careful not to pull the water pump pipe off from the water pump end (the black pipe running across the eve). I think the worst bit was having to remove the electrical connection box that sits in the way. I was a bit wary moving the cables and connections about too much.....

I got the 'O' rings from alfaworkshop. If you check on eper you can the part numbers.

Yes, but you will also need O rings for the two head inlets as shown as 9 and 10 below. Part no's are 14457880 and 14457580. Each connection actually has two O rings, so you will need two of each (including no 13 you have shown above). The eper diagrams are not that clear but the water pump pipe runs across the vee just below the two head inlets. I would also change the thermostat and gasket while you are at it.

Good luck, let me know if you need any further details......

No problem, hopefully that will fix it before it becomes more of an issue.

Agree that they are great cars, had mine getting on three years and no intention of selling...!!!
