The radiator on my car quickly loses water and the gauge on indstrment board goes up when I accelerate quickly or revolutions are loud as on the highway. when I run into the emergency lane to fill water or cool the engine and decreases the water cap is a huge pressure off the hood of even though almost no water is left. and in the coolant tank can sometimes also be empty. I myself think it is because there is air in the system? my mekanier have aired it a couple times where I can run undisturbed a long while. I have a thermostat I have been with and am not sure whether it can be the outstanding problem. Hopes high on something tackled. Greetings kenneth

find out what mechanic is doing so you can duplicate? have you had a pressure check done for cooling system integrity? you may have bad head gasket/cracked head allowing air into system.
