Nothing too scientific - I just pressed using my thumbs and gaged how much of a difference there was. There's a big difference between the stats i was supplied and the OEM so it was a piece of cake to diagnose where the problem was.... I dont have a spare OEM stat as its back in the car, but I could happily give you a duff one for comparison... Else see if Ali's still got your old one kicking about the workshop.

I havent noticed any goo around the coolant tank and I just thought that the steam may explain the loss of coolant. I'm having to top up the collant every week. When cold I top it up to the min, then keep an eye on it. Within a week its 10-15mm below the min line when cold. I'm certain its not a HGF as this has only happened since the remote stat was fitted, before, the coolant levels were fine.
Loosing 10mm in a week is a pretty small leak TBH... How many miles do you do in a week? Could be attributed to a duff tank cap if the seal has worn out with removal and refitting work recently. As i say, for a fiver its an easy bit of diagnosis! Nothing at the front of the car will have been touched as part of the stat installation, so any likely leaks will be around the remote stat its self, or around the metal coolant rail that you'll see underneath the manifold. That will have been off the car to remove the old stat and is sealed by an o-ring, so check for little drips when the engine is running and
fully warmed up. Someone holding it at 4000rpm wont hurt diagnosis, but your ears may suffer while peering up 6" away from the engine
<optimistic mode>Of course this could all be caused by air pockets still circulating, and be nothing to worry about at all.....</optimistic mode>
