Even in my car the "coolant disappearing effect" exists. Basically it happens due to one of these reasons.
1. In my case first it was a faulty hose connecting the coolant tank to the radiator cap. So everytime I wash the car I too noticed lot of green fluid flowing below left headlamp. I replaced it & everything was fine for sometime.
2. Coolant pump related issue too can cause this (try Jarpickle's Advice if the 1st point fails)
3. Head Gasket weak/cut: WHen this happens the coolant level reduces drastically everytime you drive the car. The best way to check if your head gasket has this issue do this
- Check the fluid level in the coolant tank & the colour of the liquid.
- Drive the car around for a couple of kilometers & then check the tank again, if coolant has reduced (dont panic instantly) check for the surface of the green coolant, if it has oil floating in it. It means there is a problem.
- Or if coolant tank has brown residue at its (inner)bottom
clean it & fix it back. Drive again & check if you get brown dirt again, head gasket is gone.
1st option: 30rupees 2nd option: No idea, I never saw a coolant pump/its gasket
3rd option: 1500rupees (including labour - as in B'lore) CAUTION
: PLEASE DO NOT OPEN RADIATOR CAP, atleast for half hour even after a short drive, the hot liquid splashes very badly when opened (experienced it first hand a year back).

Regarding the timing belt:
local made ones cost: 150rupees (I am using one) refer to my thread for pic.

Old gasket when worn out looks like this:
If you are replacing head gasket, then get the grooves done at the same time, will save money & effort.
