My 1994 sl 500 5.0 engine. After 10 minutes of running my car starts to over heat. I removed the t stat. I loosened the upper radiator hose and have a flow of water. give it a little gas and a better flow. Pump seems o k . Only pumps out till the water level reaches pump level. Put the car to bed at night and have pressure on the radiator cap in the morning. Any suggestions???
