My waterpump is new, all my hoses show no signs of leaks or old age and my mechanic say the pressure is normal and therefore I don't have a leak.. However, my coolant level drops below the line causing my dash light to come on every few months - this never used to happen, what could it be?

I have a 97 VW Golf. I doubt it is the head gasket as I have seen no other signs of that going. I have had fogging issue with my windshield before but not since I've moved to a drier climate and I think I've forgotten about how my car does that so I'm starting to suspect the heater core... but still am not sure.

BTW, whenever my engine is running my car is moving unless at a stoplight of course. ;)

a very slow leak that you shouldnt worry about......the car isnt new and if it passes the pressure test than dont push your luck. one thing to examine which cant be seen but it can be smelt. does your front window ever slightly fog up......do you ever smell a sweet smell in your car....could be the heater core............no biggie and dont worry about it. it will show itself soon enough and you cant prevent it

After installing any water jacket devices (water pump,thermostat,hoses or such) on some vehicles it may be necessary to bleed excess air from the top end of your engine. Experience has taught me this. First you will need to find a bleeder on your head,upper hose housing or thermostat housing.Usually this looks like a small round screw with knurled edges.Open this bleeder and air will escape as you fill it with coolant. Bleeding procedures differ from model to model so find a service manual and follow directions. Autozone should have a manual to match your vehicle.
Had this problem with a Dodge Monaco and didn't know at the time it had a bleeder.You could fill the radiator with water and go about 3 miles and it would be very hot. Solved the problem by bleeding the air.
The level is dropping because water is trying to fill the air pocket.
Also check the tail pipe and see if there is excessive condensation or steam coming from pipe. If so it could be a blown head gasket,cracked head or busted cylinder.
Some cars have a water temperature activated choking system.(Computer controlled of course) It could be leaking under the injection system(carb.) directly into the intake.
I suspect it may be sitting for long periods with the engine running. My wife does the same thing so start turning the engine off when sitting. :-p

what make and model and year of car is this?
Whens the last time the oil was checked? What Color was it? Was there any prescence of water in the oil?
Does the car smoke?
if any of these answers are yes you could have a head gasket getting ready to go, your mechanic should have thought of that though.

Sounds like a head gasket.
Any bubbles on the dipstick if you check the oil?
1. Take it somewhere for a compression check.
2. Change out the spark plugs and see if any are miscolored. You can actually "read" what the cylinder is doing by the color of the plugs.

Could be a slow leak or it could be that the radiator cap needs to be replaced....sometimes this will cause it not to hold pressure and by pass the cap as vapor thus over a period of time you lose water.

It depends on what kind of vehicle it is. If it's a chevy or ford, possibly the intake manifold gaskets are leaking internally, which is common on those. Maybe your head gasket is leaking internally?
