Green Fluid Where does this come from?

So Puma has just turned 20 years old with 160K on the clock.

Was giving her the usual underbody corrosion check this weekend and noticed the front of the engine block now sports some really dayglow, almost neon green fluid which covers the area just immediately to the right of the timing belt pulley assembly (facing the car), and runs down to the sump.

What's this from? The engine coolant is red, the washer fluid is light blue, the brake fluid is more or less clear, the power steering fluid is brown, and I know what colour the oil is :)

Only thing I can think of is maybe some air con fluid of some description? Doesn't look like it was splashed up or anything from the road.

Any ideas?

Cheers.

UV dye from the air con lubricant, should be a sealed system but the good news is the dye will normally be close to where it leaked.

Cheers. Ok, so it looks like its coating the front of the engine block from just below the alternator, running down to the sump. Is the drive for the a/c compressor located about there - is it driven from the timing belt?

Yes, AC compressor and the leak points will either be the pipe union on the right side towards the back of the pump or the pulley side by the belt.
