Angry Thats not a blower, thats my water pump!

so i get in my car and is sounded like i have pro charger installed. as cool as it was, my water pump is now pushing daisies instead of water. So I'm looking for a new pump and wanted the PN for the LS2 pump as well as an idea of any mods that need to done for proper fitment.

so is the ls2 a better pump? what about an ls6 pump, would that be a better pump and a direct fit as well?

My car also has a whining sound that gets louder as the rpms increase. I thought it was the belt. I hate the sound. So if anyone has suggestions that would be awesome! I was told it could be the alternator. But the whine definitely comes from the pulley system.

okay this is very much ur passenger side fan motor ..... very common here & even had it replaced ..... it sounds like a pully but it aint .... loosen the belt & check if the sound still runs .... or turn off the can & move the fan manually by ur hand to check !! let me know the result ....

Personally I wouldn't spend that more money unless it was an electric pump. Just go back with the stock one.

it seems like my problem. its most likely the plastic idler pulleys for the ac comprssor. one of mine have side to side movement so i cant even fix it with grease and GM doesent sell it either nor can i find it anywhere else
