Engine runs fine but impellor doesn't pump enough. need schematic on what and where to disassemble. how hard is it to check for a blockage and test for leaks sucking air.

pretty simple water Pump replacement on that one, if in doubt, buy yourself a manual and just follow the steps, does it only over heat at high RPM??
