Hi, since the coolant level keps going low,I am sure you have a leak. A sticking thermostat would not cause you to lose coolant unlees it stuck closed and the engine was alowed to overheat. I am sure that is you let the level run low enough you wil havean over heat condition . <br />The lower intake gaskets are fairly high failure items on the 3.4L engine. <br /><br /><br /><br />The first thing to do is to determine the source of the leak by looking behind the power steering pump and underneath the throttle body. Look for signs of either oil or coolant leaking from the gasket surface, especially where the intake manifold meets the cylinder head. The intake gaskets often leak from both the front and the rear of the intake and are easy to verify. The picture below shows a leak on the front side behind the power steering pump. <br /><br /><br /><br /><br /><br /><br /><br />This is what you will see; definitive proof that the gasket has truly failed. <br /><br /><br />The first thing to do is to determine the source of the leak by looking behind the power steering pump and underneath the throttle body.
