Hmm my water pump failed again!!!! Could it be the pulley?!?!
So I just had my water pump changed less than a month ago. Now it is failed again. Could it be cause of the NST pulley? Non dampned vibration at high rpm killing the water pump? Cause i do drive my car to redline every single day. I am afraid if i take it back this time they will claim it has to do with my aftermarket parts.

I've had my NST pulley on for about 6 months and 5000 miles. No problems yet. I haven't heard of any other reported problems either. It may have more to do with the abuse (red-lining) you are giving to the engine.

If that's the case, then why is this the first problem with the water pump with hundreds of thousands (if not a million) miles by everyone using the pulleys? Redlining the crap out of a car is more likely to cause stuff to break than a pulley.

the ratio of water pump failures stock vs pulley tells the tale..

The only water pump issues I've ever had was with the ol' '71 Ford. Any mechanics you could take it to that might be able to chime in? I just find it odd I've put over 50k miles with a full pulley setup on (not overdrive) without issue. Time will tell I suppose.

What about the ratio of people who redline their engine? Again that is also the other factor. And if the shop didn't install the last one correctly that could lead to premature water pump failure.
It might be worth it to run with the stock pulley for a while too, since they're in there anyway it shouldn't be a big deal. |

lol @ the denial.
Guys... if aftermarket pulleys were a 100% win/win situation, we would have lightened pulleys stock. Think about it. |

i've redlined my xA every day for 70Xthousand miles and never had a water pump (or any other) failure. stock pullies. redlining has nothing to do with it.

72k miles, redline a lot, aftermarket pulleys.
I'm just saying don't be so quick to blame the pulley. There COULD be other factors. |

The denial comes from ignoring the blatant admission of redlining the car everyday. Redlining DAILY will definitely do some damage under the hood. If your car was designed to cruise at 6/7/8 RPMs, then there wouldn't be a red line, period. I'm sure you've been doing some serious damage to your engine, especially considering that you most likely have stock (economic) internals. I don't see how anyone can argue in favor of redlining and against an aluminum pulley that is only 10% less than the stock pulley in circumference!

I personally think it has to do with installation of the pulley. Check the belt it may be slightly misaligned or too tight.
