Hi everybody. Planning on purchasing a water pump and have a question. Before anything, I did search and have read plenty of thread but still have a concern.
There are currently 2 AC Delco water pumps that would work in our cars:
- AC Delco 252-700
- AC Delco 251-555
The 252-700 I've seen around $100 while the 252-555 is ~ double in price.
We know the 252-700 is made in China and has worked well for some members. My question is this: Is it cheaper because it does not include the gaskets, the thermostat and its housing, and the coolant temperature sensor?
From the pictures vendors post in their ads those are the only differences I see. For the forum members that have purchased the AC Delco 252-700, could you guys let me know if it's just the pump?
Also, assuming it's just the pump, what is the AC Delco or GM part for this sensor (mounted on the front of the water pump) in case I have to buy it separately? I know there are other sensors (i.e. on the side of the block) but I am getting confused which part number belongs to which. Is it AC Delco 213815 (GM 10096181) the one I need?
I will appreciate your help.
