47 Flathead Water Pump Swap Tricks?

The answer to your question is...yes, it can be done with radiator in place. Remove only what you need to. Take your time and take a few breaks during the job. Since you know about the bolt inside the pump inlet (where lower hose attaches), I would caution you to be extra careful removing it. If you break it off, it's a real PAIN to repair. If they both come out cleanly, put a dab of anti-seize on the threads or use stainless bolts.
