What is a water pump and how does it work?

The water pump is a belt or chain-driven engine accessory bolted to the engine above the crankshaft pulley. The pump housing has an impeller that circulates engine coolant through the cooling system passageways in the engine block and cylinder head, on to the radiator, where the coolant temperature is reduced. . The lower temperature coolant then flows back to the water inlet on the engine and the water pump continues the cycle.

When to consider replacing the water pump:

  • Coolant leaks or overheating. The water pump impeller shaft is supported by a bearing. Eventually, the bearing or seal can wear and leak or damage the impeller. Many water pumps have weep holes near the pump bearing. If you see significant leakage from that weep hole, it is time to replace the pump.
  • Bearing roughness or noise. If the water pump shaft does not turn smoothly or the pump is noisy, the bearing is excessively worn. Pump replacement will be necessary.
  • Timing belt replacement. In engines where the water pump is driven by the timing belt, it is a good idea to replace the water pump at the same time the timing belt is replaced. The extensive work explains why it is always recommended to replace the water pump whenever the mechanic already has these components removed for regularly scheduled timing belt replacement.

How do mechanics replace the water pump?

  • The water pump is usually bolted to the front of the engine. The replacement procedure will vary depending on whether the pump is driven by the timing belt, the serpentine belt, or chain.
  • On a cold engine, the engine coolant is drained to a level below the water pump.
  • Components that require removing to access the water pump are removed, including the belt or chain that directly drive the pump.
  • The bolts holding the pump to the engine are removed and the pump is pulled out.
  • The gasket surface must be cleaned and the pump mounting surface inspected. A new gasket, rubber seal, or RTV sealant, as required, is installed and then the new pump. The bolts are torqued in sequence using a calibrated inch pound torque wrench.
  • For applications where the water pump is driven by the timing belt, the timing belt must be removed. Typically, this requires removal of the crankshaft pulley, timing belt covers, and timing belt tensioner. Once the new pump is installed, new coolant is added back while bleeding the cooling system of any air. The engine is then run and brought to normal operating temperature to check for leaks and ensure normal operating temperature.

Is it safe to drive with a water pump problem?

No. Should the water pump only leak a little bit, you can drive the car. However, a small leak could suddenly enlarge or the pump bearing might unexpectedly seize. Either circumstance would likely cause engine overheating. If a defective water pump causes the overheating, it is not safe to drive because of the damage to the engine.

When replacing the water pump keep in mind:

  • It is best to install a new cooling system thermostat when you install a new water pump, especially if the thermostat is old or original.
  • Completely flushing the cooling system is a good idea when you replace the water pump. Flushing can be done before or after pump replacement.
  • The rest of the cooling system should be inspected too — particularly rubber hoses, which have a limited lifetime.

98 1995 - Oil Pressure Light is on - Houston, TX
They just sent an email saying the mechanic is on his way. It is only 8:12 am! He is off to a good start. He is supposed to arrive between 9:00-9:30 am. He arrived well before that time! It was not 9:00 am yet! He did a diagnostic and he checked all the work I did. He said I did great work with everything I did. He said the car is very good shape. He said this car is indeed a runner! He checked everything. He checked all the fuses and relays too. He did a complete diagnostic too. He checked fuel pressure, oil pressure, and more. He found out what it was. It had nothing to do with oil pressure or anything. The fuel pump is going out. When he came the car started right up. He said they never go totally out. He said that is why it started when it did. He connected tools I do not have to the Ninety Eight. It is not getting any fuel pressure, and this is why it shut off all the times it did. He fixed one of the spark plug wires too. It was burnt. He jacked the Ninety Eight up and got underneath and checked the wires, the oil pressure sensor/switch and oil level sender for everything and the connections and made sure they have power and were installed correctly. He said the engine uses oil pressure along with the fuel pressure to start. The fuel pressure is non existent and that is why it would not start. After all of that, he looked at the Oldsmobile Toronado, my other car . He got the air conditioner to work again. He said the compressor bolt was loose and he tightened it up. He used this huge screw driver device and bent it back in place. He said the shims were loose and he bent them back. It cools just fine now. We turned it on and off several times testing it. He checked the pressure and it was filled with refrigerant. He checked the relays and the fan too. It was all fine. He said it is clear you take care of both of your cars. He said one thing I will not do is guess and I like to know what is indeed wrong. He said your cars are in good shape. He said you do not need valve cover gaskets. There is no leak. I booked him to return to install the fuel pump I need. I look forward to seeing him again soon in a few weeks. Today only cost me 70.00. That's it.

98 1995 - Oil Pressure Light is on - Houston, TX
The mobile mechanic came. I must say I am impressed! He found my house. He and I started talking. He said he owned two Ninety Eights previously. He was there to look at my Oldsmobile Ninety Eight. He had two Oldsmobile Ninety Eight Touring Sedans. The ones he owned were from the 1987-1990 era. He was describing the floor shifters and they had and how much he liked Ninety Eights, Touring Sedans, and the Oldsmobile Eighty Eight LSS too. He talked about how a family member owned one and how he was fixing his. He talked in detail about the Touring Sedan and the things he loved. He asked me how long had I owned my Ninety Eight. I told him 2003. He told me how he become a mechanic and went to school for it and more. He got into the Ninety Eight and it would not start. He got out and disconnected the battery and rubbed the negative and positive battery terminals together. He reconnected them and the Ninety Eight started! The instrumentation then told him exactly what it was. There is a sensor at the bottom of the oil pan. He said by doing what he did with the terminals, it cleared the computer and reset it. We went underneath the car and he showed me the sensor. He said which one did you replace? I told him. He said you were on the right path. You know what you are doing. You need to replace this sensor and not the one you did. You can get the sensor and replace it because it is clear you know what you are doing and on the right path. He said you also need to replace your valve cover gaskets. They are leaking. I told him I will request him to come back and do that. I am not doing that even thought I can.
