Still absolutely ridiculous for the size of this thing! Especially when you consider how many of these were engines were made. It's not like it's a small, limited run.
I agree. Its good the unit is easy to replace. Have you considered a different aftermarket brand? Not all chinese parts wre created Equally. Rock Auto has a good variety:
I bought an AC-Delco for $200 from a local supply house.
Every DIYer should try RockAuto.com. They are a drop shipper that has negotiated fantastic prices on real name brand aftermarket and often OEM parts. An AC Delco water pump thru them for the 5.9 diesel Part number 252318 is $53.00. Shipping is probably $12-$15. No bootleg illegal counterfeit versions like what is often purchased off Amazon.
