The only thing that ever happens to the water pump is bearing failure, seal failure, and I have seen the impeller loosen and walk off the shaft until it rubbed on the engine case. If a past bearing failure occurred the case can be damaged and enough wear here can reduce pump efficiency at low or idle speeds. If the engine is cooling the pump is fine. If over pressure is happening you need to check/replace the pressure cap and be concerned about loose/cracked heads allowing combustion gasses into the cooling system.

Is there a way to test the output of a water pump?

My '89 Carat with automatic blew the coolant line that goes from the side of the thermostat housing to the "T"-pipe a week ago (it was 95¹F outside, here in Texas). The hose is now replaced, but I'm worried that there may have been some factor other than age that made the line blow.

The Carat has about 125K miles, and about 10K of those are mine. The previous owner claimed to have had the engine rebuilt, but there's no telling either when that was or whether the water pump was replaced. --
