Recently I have started to notice that there's coolant (presumably) leaking from the engine. There's no obvious leak when you look at the engine from below right after you have driven it, but it leaves a puddle on the ground after it's been parked for several hours. The engine seems to be working fine, haven't had overheating issues, but I'm losing coolant and I'm afraid if I don't do something it will lead to bigger issues. Any ideas what could it be?

The car is 5 speed Holden Astra 2001 sedan The puddle on the ground http://design.imago.ee/test/auto2.JPG The place where it seems to be dripping from http://design.imago.ee/test/auto3.JPG

The engine size was not provided. This suggestion is for the 2.2 litre engine.

The water pump on the 2.2 litre engine is driven by the timing chain. If it is leaking from the front seal this will drip water into the sump oil.

If the water is dripping onto the ground it is probably the "O" rings on the pipe that cross between the water pump and the thermostat. These are easy enough to replace but you may have to remove the exhaust manifold to access the pipe and then remove the thermostat to remove the pipe. A standard "O" ring from your local parts store should fix the problem.
