How does a bad water pump sound? Im getting a high pitched whistle sometimes when I give it some throttle.. I know I replaced my water pump with a metal impeller (Graf) about 2 years ago.. Im also only getting heat when I rev to about 4k RPM its gonna be a cold winter.. no its not air. as a side note, due to a hole in between my head and block that shoots coolant out, i was forced to resort to a stop leak product. i was fine for about 2 years like this. looks like that crap has caught up and clogged all types of stuff up.
