it installed. All those related components have ~6k miles on them. So, premature water pump failure, I'd guess so if that's my culprit. My other issue is low compression in two cylinders, assumed bent valves (as discussed in my previous posts). I was curious though, if the condition of the coolant could force the water pump to leak through the weep hole? My coolant was murky and brownish. Wondering if I flush it good could this improve the water pump function?
