This past Monday my engine overheated twice. The impeller and thermostats were replaced a year ago. The overheating problem only occurs when running at 3,500 rpm or above. I noticed that when I get above 3,000 rpm my water pressure starts dropping. When running below 3,000 the gauge indicates about 7-8 pounds pressure. When I get above 3,000 rpm the pressure drops to 2-3 pounds pressure. The water coming out of the site check hole seems fine at low rpm but seems to drop off at higher rpm.<br /><br />Questions:<br /><br />1. Shouldn't the water pressure gauge show increased pressure rather than decreased pressure at higher rpm?<br /><br />2. Any ideas about the cause of the problem?<br /><br />Thanks
