It may be pointless, but here's a quick tip: There should be some threaded plugs at the top of the water pump. On my IH 7.3, they are regular NPT thread, so you can use generic plumbing stuff from Home Depot. Easy way to put a temp sensor, shutoff valves, tee fittings, aux lines, etc into the cooling system.
