While on the subject, my waterpump had to be replaced on my 360 Magnum 'cause the bearing was screwed. No wonder: that humongous fan on there leaning on a bearing not much bigger than your thumb didn't last very long.

Solution: ditched the fan, put a new water pump on and went to an electric fan. Fuel mileage went up and the water pump should last 5 times longer.

Hopefully last longer anyhow. Changing the water pump is a bit of a chore and would not like to have to do it again anytime soon.
