Water pump kit with housing
by Andrew from Auburn, Pennsylvania on September 01, 2013
Everything came promptly and was included, but housing was too large to fit correctly. Had to use the old one, now I have a spare that is too large for my motor. Wouldn't buy Sierra housing again, but everything else included was okay. I essentially overpaid for the items that were supposed to fit correctly and was only able to use wear plate, gaskets, boot, impeller, and bolts. Seems wasteful...
