Water Pump Repair Kit 18-3394
by Leslie from Rock Hill, South Carolina on April 28, 2015
There isn't much to say, the kit has everything you need to rebuild your water pump. Just follow the directions.......I forgot, there are no directions but all the parts are there. If you need directions you should not be doing this repair by you self.
