Jim:

Peter is correct about the Craftsman cotter pin removal tool. I have used one for many years, never to remove cotter pins, only to remove hoses without damaging them. If you really want something to never seize the hose, try silicone paste grease in very small amounts. Only do this if your radiator has the raised ridge or end flare around the hose neck that prevents slipping. Virtually every radiator neck is built this way. But, I have seen radiator necks where some meathead has hack sawed off the flare so the hose will slip on and off easier...go figure. Place the clamp behind this flare, tighten it well and it should never come off past the flared ridge.
