Honda 19200-RDV-J01 Water Pump (Yamada)

Disconnect the cable from the negative battery terminal. Drain the cooling system. If the coolant is relatively new or in good condition, save it and reuse it. Remove the drivebelts. Remove the timing belt, and remove the timing belt tensioner. Remove the bolts and detach the water pump from the engine. Check the impeller for evidence of corrosion or missing fins. Clean the bolt threads and the threaded holes in the engine to remove corrosion and sealant. Compare the new pump to the old one to make sure they're identical. Remove all traces of old gasket sealant and O-ring from the engine. Clean the engine and new water pump mating surfaces with lacquer thinner or acetone. Apply a thin layer of RTV sealant to the 0-ring groove of the new pump, then carefully set a new 0-ring in the groove. Carefully attach the pump to the engine and thread the bolts into the holes finger tight. Use a small amount of RTV sealant on the bolt threads, and make sure that the dowel pins are in their original locations. Install the remaining bolts. Tighten the bolts in 1/4-turn increments. Don't over-tighten the bolts or the pump may be distorted. Reinstall all parts removed for access to the pump. Refill and bleed the cooling system and check the drivebelt tension. Run the engine and check for leaks. Reconnect the battery.
