Alternator fried at about 17k and water pump replaaced about the same time when it started to chatter at tickover. IC pump still OK (tempting fate). I wonder is the lifespan of the Bosch related to ambient temperature?

It barely breaks 25C here in the summer and that's only for a few days. Could it be that the hotter regions kill the pumps earlier than the more temperate zones?
