This weekend's job was to change the thermostat & gasket as there was water seeping out from it.
In my infinite wisdom I didn't check when I ordered the parts and discovered I needed 2, not 1 gaskets on the thermostat housing. Clever boy.
I went to my local car parts shop to buy another gasket. This is a 'universal' one, and it's literally just a piece of cardboard. It looks like it's been punched out the back of cereal box or something!
Is that alright? The other one I have is from Minispares and is what I'd call 'proper' material: the fibrous-slightly-papery type of material. It's just that in my experience cardboard isn't a waterproof material...
