I've got an Octavia 1.8 (5 valve per pot Audi engine) which is losing a bit of water, maybe 1 litre a month in the last 2 months. Immediate thoughts were a cooling system leak, but no apparent leaks have been found. Next came grim predictions of a head gasket leaking, now I'm hoping it may be a water pump leak.
So, is there any way of checking for the leak without dismantling everything? I'm due to do a cam belt change soon anyway, is is wise to change the water pump then, just as a preventative measure, even if the water pump is not leaking (and is the water pump near the cam cover - I've never had this car aprt?)
Or, could this be natural wastage?
Thanks for any thoughts. Alan.
