I see this is old but the info is still relevant.
I'm driving a 1996 Coaster model HZB50.
Some sadist put the expansion tank under the bus in front of the driver's feet.
Checking the level involves lying on your back on the ground, worming under the bus, pulling the lid off the tank and then putting a small dip-stick, or your finger , into the tank to check the level.
No, the tank is not transparent enough to see the level from the outside.
Even with a torch.
