Using coolant? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 2002 Silverado with the 4.3. About 87,000 miles. I have the water fall sound under the dash.I have to fill up my coolant every so often. I think its using a little more as time goes on. I heard these motors might have intake issues or water pump problems. I never see water on the ground. Maybe it leaks internally and is evaporating. My question is, can I put some of the old school stop leak in the overflow tank. The gray powder stuff you might use on your old Chevy? I'm not sure how the newer vehicles might react to something like that. Please give me your thoughts. Thanks
