Coolant leak

Hello
Drove about 100 miles yesterday for bank holiday weekend. Couple of hours later noticed coolant dripping of exhaust manifold. Put container under van overnight and collected about half litre. The expansion tank level hasn't dropped at all. Why would this be?
Halfords nearby so will top up today.

Your header tank should always be full, you need to trace the leak, start it up and have good look around to see if you can spot where it's coming from.

I found the leak. Hose clip rusted and not tight enough.
Topped up header tank. Coolant bit mucky in there.
Expansion tank coolant is pristine.
Does this mean it's not being used?

Probably as it's a sealed system, now you've sorted the leak it should work fine. Go for a spin and get it up to temperature, recheck the tanks and your recent repair.
