  • Step 1 Place a drain pan underneath the radiator. When the engine is cool, drain the cooling system from the radiator into the pan and disconnect the negative battery cable.
  • Step 2 Take the accessory drive belt out of the engine and disconnect the heater hose from the water pump.
  • Step 3 Remove the lower radiator hose from the engine (unless you are working with a diesel engine).
  • Step 4 Disconnect the heater hose from the pump, remove the upper radiator hose and take out the fan and shroud assembly.
  • Step 5 Loosen and remove all 4 bolts from the water pump pulley and take out the pulley (except on 4.7L engines) and loosen and remove the bolt to the heater hose pipe.
  • Step 6 Loosen the clamp to the bypass hose attached to the water pump (except on 4.7L engines) and remove the 7 bolts connected to the water pump. Remove the one nut in the 4.7L engines. Take note of the bolts locations, as they are of varying lengths.
  • Step 7 Clean all mating surfaces and install the new water pump with a new gasket and o-ring, lubricating it with petroleum jelly. Tighten the bolts to 40 foot pounds (54 Nm) on the 4.7L engine, and 30 foot pounds (40 Nm) on the other engines.
  • Step 8 Install all components in the reverse order in which they were removed. Use sealant on the heater hose pipe when installing and tighten the nut to 12 foot pounds (16 Nm), making sure that the pipe bracket slot is against the mounting bolt. Tighten the pulley bolts to 16 foot pounds (22 Nm) on the V-10 and 20 foot pounds (27 Nm) on V-6 and V-8.
  • Step 9 Reconnect the negative batter cable, and refill the engine's cooling system with coolant. Start the car and check for leaks when the engine reaches normal operating temperature.

  • Step 5 Take out the power steering pump.
  • Step 6 Loosen and remove the four bolts to the water pump, taking note of their locations as one is longer than the other bolts.
  • Step 7 Install the water pump, making sure to install a new gasket, tightening the bolts to 22 foot pounds (30 Nm). Apply a bead of silicone to the gasket making sure the silicone is facing toward the water pump when installing.
  • Step 8 Reinstall and reconnect all components in the reverse order in which they were removed.
  • Step 9 Reconnect the negative batter cable, and refill the engine's cooling system with coolant. Start the car and check for leaks when the engine reaches normal operating temperature.

    You will only need to replace the pump if it may a high screetching sound and killed the motor. If it is not leaky and not noisy, then you shouldn't have to replace it.
    If you feel you want to replace it, you can pull then belt off, pull the hoses, unplug the temp sensor, remove bolts and pull if off.

    You can go to autozone . com and register and then login and view a free repair manual that I recommend.

    I have a 1999 Camaro I have no thermostat in it have the cooling fan wired up direct with a new radiator it seems that sometimes the water pump pumps water and sometimes it doesn't I don't understad


    the pump will pump water at full blast without the thermostat
    unfortunately if the radiator cores are blocked then that description is indicated
    try replacing the radiator with a new one and refitting a thermostat
    with a new radiator you are very likely to get an over heating problem as the pump will pass water quicker that it can be cooled and so the water temp will continue to climb

    Heat doesnt work


    check your fluids radiator should be full and resavor should be at full level if you dont have enough anti freeze it wont push fluid into your heater core also pay attention to your tempature gage if the temp is low you wont get good heat your thermostat could be stuck wide open I would try adding anti-freeze first though that usually fixes it make sure its 50/50 if you just add water sooner or later that water will evaporate

    The coolant is getting hot causing the engine to overheat.


    This could have several causes. Is the coolant tank full? Is the coolant relatively fresh and a 50/50 mix of water and antifreeze?
    Does the heat gauge jump up to hot and then fall back rapidly at some point or just rise and keep climbing? If so, it is the thermostat. Is there a leak evident under the car? If so, it could be a bad water pump. The water pump has a small weep hole and if there is water at that point the pump needs to be replaced. If none of this is the cause, then it could be a plugged radiator or a faulty cap located on the radiator or the coolant overflow tank.

    I have a 1990 Buick Regal v-8 Does the radiator fluid move from radiator to reservor as engine heat and cools or remain in radiator except under extreme heat conditions?


    A certain amount will run into resavor or draw out after it is shut off no matter what the tempature is, the only exception is if it is low on coolant in the radiator it will draw out of the resavor to maintain the right amount to the cooling system. but when engine is running it should not do either one because the coolant is flowing.
