For my education, what does the water pump bearing noise sound like when it's starting to fail? My 76k 01 M Coupe has no water leaks, fan wobble or cooling issue (and it's summer in Vegas), but every second or third time I start it it makes a repetetive chirping like a noisy fan belt. The noise eventually goes away once the engine warms a little. Anyone think this is impending water pump failure? Thanks in advance for your expertise and opinion.
