Possible air trapped in the coolant system caused be a head gasket leak into the coolant. For about $25.00 you can get a block tester from any parts store. This will let you know if there is exhaust leaching into the coolant. Google block tester. If you find its a head gasket leak. It's remedied by replacing the head-gasket. Or a quick fix with SteelSeal.com
