I think my water pump is leaking on my 98 nissan altima


Very possible. The water pump will be run by the timing belt behind the engine cover and on the same side of the motor as all your external belts. Make sure there are no hoses close by that could be leaking and if not it will probly be the water pump. Usually they will make a noise when they are failing. Remeber if it is just a drip and it is hot outside if you run your air conditioning it will drip water from the condenser as well.

Lower radiator hose stays cold after running for hours


could be you fitted the thermostat in the wrong way around ,or the plastic impeller on the water pump with a steel drive shaft has failed they end up with the drive shaft spinning but the impeller is not turning ,go for the thermostat first though .

96 nissan altima with ne water pump and thermostat


1. Improper water circulation: Sometimes, eventhough you are sure that you have enough water on your radiator, your car still overheats. It might probably be that the water is cannot circulate properly, which results to improper cooling process. There are several reasons for this which you can discover by yourself. To verify if the water circulates properly, start your engine without the radiator cap. If water circulation is good, you should notice that the water pops smoothly over the top but still retains the amount. Another way to check, detach one of the ends of your radiator hose from your radiator and see if water flows continously over.
If water doesn’t circulates well, check the thermostat if it’s open. It should be open, meaning clean, and the water can pass through it.
If thermostat is clean and still the water doesn’t circulate properly, then you have to check the water pump. That’s probably where the problem is. A little leak on the pump will cause improper flow of water through the radiator system.
If you are sure that the problem is not about water circulation, another thing you can consider is check the engine oil. Very low amount of oil can cause greater friction of the mechanical system of your engine. If it’s not time to change oil yet, you can add over some amount of oil until advisable amount is reached.
While we can’t be always sure about our engine, especially if it’s not new, we should be prepared when it happens. Bringing extra gallon of water in your trunk will surely help.

1996 nissan altima running hot changed thermostat new radiator you can drive it an hour before it runs hot


check the operation of the fans, since the radiator was recently replaced, it is posible they may not be plugged in correctly or operating like they should, if they look good, look into the water pump, with the work that u already did the only this left to look at after the water pump is the intake or head gasket, any water in oil or vice versa? look into that if all else fails....

Have to replace water pump on 98 Ford Taurus. Any hints or suggestions would be appreciated before I get out in the snow and cold to fix this.


You can change the water pump by doing these steps:

  • With the engine off and cold, o pen the hood and locate the vehicle’s radiator and water pump.
  • Remove the radiator cap.
  • Install a pressure tester on the radiator. Apply the pressure indicated on the radiator cap or in the owner’s manual.
  • Inspect the water pump for leaks. Remove the pressure tester.
  • Place a drain pan under the radiator. Open the drain valve or remove the lower radiator hose to drain the cooling system.
  • Remove the drive belts or serpentine belt.
  • Remove any hoses connected to the water pump.
  • Unbolt the water pump from the engine. Remove the water pump.
  • Using a gasket scraper, clean the mounting surface on the engine block.
  • Install a new gasket and attach the new water pump to the engine with the original mounting bolts. Tighten the bolts to the manufacturer’s specifications.
  • Re-install any hoses and belts that were removed.
  • Re-install the drain plug or lower radiator hose.
  • Refill the radiator with a 50/50 mix of coolant and distilled water. Pressure test the cooling system and check for leaks.
  • Check and fill the overflow reservoir with coolant.
  • Leave the radiator cap off and start the engine. Idle the engine to remove trapped air from the cooling system. Add coolant if necessary.
  • Install the radiator cap.
  • Road test the vehicle and monitor the temperature gauge. If the vehicle runs hot, there may be an air pocket in the cooling system. Allow the engine to cool off and add the necessary coolant.

Radiator fan running after engine turned off on 98 nissan altima


You need to diagnose the problem. The fan is doing what it is being told to do by the computer. You stated the temp gage on the dash is in the HOT position. Either the engine is very hot and the fan needs to run to remove heat even after it is shut off or the gage, coolant sensor or temp sender is defective. Try running it temporarly without a thermostat and see what happens, you may have bought a defective thermostat.

I have a 94 nissan altima that overheats. I


sounds like where the water pump meets the engine has warped or the gasket has been blown. Since the water pump has to come out anyway to fix it then i would suggest replacing the pump. It is 30 to 40 more.

98 deville runs hot. i have already changed thermostat


You likely don't want to hear this but Northstar engine a common for head gasket failures. One good test that I use it to fill the coolant tank all the way to the top. Then start it up. If the coolant shoots out of the tank. The heads have a problem.
