The job is time consuming due to the number of bolts and connections that have to be removed. If you are confident in replacing a water pump you can do this job if you have the right tools and equipment. Although a car lift is preferred, you can do the job on the floor of your garage provided you get the car safely supported a couple feet off the ground. Here is a short list essentials that are explained in more detail in this manual.

  •  A good strong helper - for safely do not try to do this job alone
  • Large heavy duty floor jack, jack stands or car ramps if doing this on the floor (lift of course is easier)
  • 1/2 inch drive heavy duty 10 mm hex socket (allen) for starter bolts
  • 2 to 3 feet of 1/2 inch drive extensions ( these can be ganged together)
  • Large channel lock pliers to loosen drive shaft
  • Good assortment of metric allens, sockets and wrenches
  • 3/4 inch plywood plate to balance transmission on floor jack (if required)
