Upper radiator hose popped at the radiator side

Hello people,

Today I found out that the howling noise is actually coming from the water pump and not alternator as I said before. I find it very weird for it to happen since it only has around 10k miles on it (maybe even less). It might have been some manufacturing defect.

I don't know if a slightly shorter belt could have caused it. When I got it, the computer at autozone listed two belts with only 1/2" difference. I got the shorter one because they didn't have the other in stock. The tensioner has about 1" of play when releasing the tension so I really don't think it's putting too much stress on the bearings.

Even when I haven't had any responses lately, I will appreciate if anybody has anything to say on this matter, I want to find other possible causes before the new pump fails again. Thanks in advance.

Oscar.

I replaced the pump yesterday and drove the car today, no noises.

Upon inspection of the old pump, I found some corrosion where the shaft meets the impeller which is very odd since it's supposed to be submerged in coolant. It must have been a manufacturing defect for sure. The bleed hole also had traces of coolant leaking from it; I don't now how I missed it, I used to think that the lose of coolant was caused by a faulty rad cap...
