  Q: How to replace a water pump in a Acura MDX?

  A:

  Disconnect the cable from the negative battery terminal. Drain the cooling system and if the coolant is relatively new or in good condition, save it and reuse it. Remove the drive belts, followed by the timing belt, timing belt tensioner, and adjuster assembly. Take out the mounting bolts and detach the water pump from the engine. Clean the bolt threads and the threaded holes in the engine to eliminate corrosion and sealant. Compare the new pump with the old one to ensure they are identical. Remove all traces of sealant or O-ring from the engine mating surface. Clean the engine and new water pump mating surfaces with lacquer thinner or acetone. Apply a thin layer of RTV sealant to the O-ring groove of the new pump, and carefully set a new O-ring in the groove. Attach the pump to the engine and thread the bolts into the holes finger tight. Apply a small amount of RTV sealant on the bolt threads, ensuring any dowel pins are in their original locations. Tighten the bolts, reinstall all parts removed for pump access, and reconnect the battery. Finally, refill and bleed the cooling system, check the drive belt tension, run the engine, and ensure there are no leaks.
