I looked it over and discovered that the top radiator hose was colapsing at the 90 degree elbow right above the thermastat housing. I took some 12 guage electrical wire and rapped around the hose there to prevent it from colapsing and took it for a spin, it didnt overheat and ran much cooler. So i baught a new upper hose and installed it. now it dont overheat but it sure runs hot, right on the edge of overheating. Plus the new hose is trying to collaps but the wire inside is preventing it. Does anyone have any idea why its running so hot and why the hose is colapsing?</p></blockquote><p></p>
