It sounds like its over heating
Hey. The reason why your engine is over heating is 1.),Your engine has dirt and other gunk in it, or,2.)You need a new filter, or3.), your engine doesn't have a filter and you need to get one. The filter I recommend is the filter with the orange micro-fibers in it. I do not remember the name of it offhand, so I'll try to get back and tell you. - 11Hilsonn
