Looking for some help here. We just overhauled the engine in a 6x4 with the Kaw. Fd620d. One head ( the one that takes the upper radiator hose ) gets considerably hotter than the other side. I have removed the thermostat, blown through all the water lines ( upper and lower rad. hoses ) and get circulation. I am guessing the water pump is not circulating like it should. Even more curious, is the fact that this cylinder had thrown the rod and appears to have been running hot before the rebuild, from looking at the exhaust manifold.
Anyone have ideas???
