So I decided today was the day for a nice thermostat change as the seal has apparently decided to no longer seal.
I had my replacement all ready, but obviously it is hard to tell before taking the whole thing to pieces if it really is the right one or if Eurocarparts are just idiots. Sadly, it may be closer to the latter.
As you can see, different sizes! (The old one is on the left). The seal was pretty crusty and has a small hole, which is probably where the leak is from, as I've rotated the seal on reassembly and the drip is now seemingly at that point. So, would anyone have one of these knocking about? Or a source for the correct 'stat+seal?

Looks like a sewer pipe or something!

Isn't this was latex gloves were designed for?

This hose was nice and soft

But this one is starting to disintegrate nicely. Does anyone have one of these or know a source? It's the slightly smaller lower hose from the 'stat housing.
