How do I know if my coolant tank has split??

Started the Zed this morning only to be greeted by the coolant warning light and no water in the coolant tank. Wet on the right hand side of the undertray but I can't se any obvious leak even after I've topped the tank up and run the engine hot. Any ideas would be welcome. :(
 
Erm... do you mean right-hand side as you look backwards into the bonnet?
I'd expect it to be mostly under the expansion tank.
Mine was the same: no sign of a leak apart from the puddle of water.
On mine it turned out to actually be the o-ring seal where the expansion tank fits into the housing, but as you have to take the tank out to get at it, why would you risk putting the old one back in.
As you have a Clutch Valve Delete, I'll assume it must be manual? Wifey's is an auto and had a valve assembly sitting in the bottom of the housing which broke and fired in all directions, necessitating a wait until a new one arrived, but I have a feeling that's autos only. Something to do with the oil cooler??
If you change the tank check all the o-ring seals inside the hose ends as these may have gone a bit flat.
Luckily I had a big box of assorted seals to replace mine with.

If you actually do mean the drivers side of the engine bay, then maybe more likely to be the water pump or the thermostat housing? But I think you'd see drips around them.
