SBS7295X on 74 at Marymount Road, Blk 319 at 1830 - driver was
seen pouring bottles and bottles of water at the right back of
the bus (fuel tank?)...can someone explain what's this for?
Bus was seen running at Upp Thomson Road 20 mins later.

Water is to cool down the bus engine component (not very sure
what it cools). Likely the bus ran out of water and BC risked
overheating the engine.
Just one thing, how the BC get so much water to pour into the
engine? thought BC carry 1 bottle for personal consumption
