Mine is a 95 Blazer, which adopts many mechanical parts from other very old siblings from 80's, and makes huge differences from 96-05 blazer models. The OE water pump for 95 model is AC Delco 252-719, and 96 + models uses AC Declo 252-711.

At present, the engine always runs overheated, and found the coolant leaks from the water pump in large amount. Need buy a new replacement, however, 95 model's pump is difficult to source in my area, and AC delco's staff declined to tell if these two models are interchangeable, anybody has any idea or suggestion to help? or does it mean i have to rebuild the entire cooling sys, including clutch, fans, hoses, even radiator instead of replacing a single pump???

Thanx in advance!
