Question about 1997 Chevrolet Malibu
I have a lot of coolant coming out of the overflow tank. Have to add coolant once a week when the low coolant light comes on the dash.
It may be you have a leak in your head gasket and the coolant is burning up in your engine. Does your oil look milky at all and is your exhaust smoke white at all. It may be a small enough leak that it burns off enough without any symptoms other than you having to fill up the tank..
Now you can test if you have a leak in your head gasket. If your pressure cap is good, start the car cold with radiator cap off, (and radiator full), it will put up steady bubbles, the worse it is leaking the worse the bubbles will "flow"!
An occasional "small bubble" is not a problem, as it will push out air trapped inside engine till it has heated up and thermostat has opened.
Another cause could be if you had the thermostat changed and it was inverted by accident. The "pellet" end (one with the little "wart" around the shaft from top to bottom), goes down in water (from engine)

Check your intake manifold these cars are known for leaking water internally, is there a foamy yukky looking material on your oil fill cap? If yes it is leaking and if not repaired will ruin bottom end of engine...Anti freeze and oil are not best friends and this can cause severe damage.
