Question about 2002 Nissan Altima

1 Answer

Running hot water pump was leaking (i noticed because fan didn't kick off when car was turned off so we checked water level). we replaced water pump and belts and car runs hot...so we replaced the thermostat, then radiator cap, then flushed the system (thought an air pocket could be problem) but car still runs hot! top radiator hose gets hot bottom one does not. we also ran it without a thermostat and still ran hot! help

Water Pump leaks from the front end of the Wagon.


follow this steps and fix it. God bless you
  1. Determine the Reason for Water Pump Failure
    • 1 Repair a water pump by checking your car for a failure in the bearings. You can test for bearing failure by seeing if there is any play in the shaft that is connected to the electrical fan blades, as well as the drive pulley to the pump itself.
    • 2 If you notice any free play in the shaft or the pulley, you will need to take the pump apart and replace the bearings.


    • 3 Determine if the water pump failure is due to a leak in the casing. Examine the water pump housing for leaking or water stains in the drainage hole next to the pulley.
    • 4 If water is dripping from this hole, then the seals inside the pump need to replaced in order to repair the pump.
    Remove the Water Pump for Repair
    • 5 Allow the engine to cool completely before removing any part of the cooling system. Never open a radiator cap or plug while the engine is still warm.
    • 6 Disconnect the car battery. This will prevent the electrical fan from turning on while you are under the hood.
    • 7 Drain the radiator of all fluid and disconnect the radiator hoses. Collect the fluid with a plastic container and keep it in a safe place until you are ready to put it back into the radiator.
    • 8 Remove the fan assembly. This will include the shroud, the fan and the fan belt. Disconnect the electrical leads for the fan.
    • 9 Remove the pulley for the fan belt as well in order to have access to the water pump.
    • 10 Use a socket set to remove the water pump from its engine mount.
    • 11 Open the housing for the water pump and replace the seals or bearing as necessary. Some auto parts stores carry repair kits that have both the seals and bearings for specific types of water pumps.
    • 12 Reassemble the cooling system by replacing the water pump, pulley, fan belt, fan assembly and radiator hoses. Refill the radiator with the fluid.
    • 13 Start the engine to see if the water pump repair was successful. Check for leaks before you take the car out on the road.

2005 mustang is overheating and shutting off. Turned the key and it won't stay on. I noticed that the fan might not be turning on. How do I troubleshoot? I put water in the radiator and didn't...


It could be a leak, check your radiator for any leaks, also check upper and lower radiator hoses, water pump, etc. But you said the fan doesn't kick on even when it's reading "hot". So I would look into that more. route the wires and locate the plug, make sure it's plugged in, or reseat the cable by unplugging, and replugging it back in. You could also unplug the negative cable on the battery terminal for a few seconds in attempt to reset the ECU (computer).

Engine is running hot


Check coolant reservoir level, check cooling fan if working, check if no leaks on the water pump...If engine newly installed, chances are drive belts are not installed properly.

2005 grand cherokee squealing and loss of coolant


Check belt tension, squeeling is most likely due to belt slippage. Have you noticed any fluid leaking from under your Jeep? Coolant level drop could be from bad water pump, when the pump needs replacing, water flows out of a "weep hole". It could be leaking onto your belt also, causing it to squeel

The engine is overheating. Removed the thermostat, radiator fans not kicking in, noticed collant leaking from were the water pump is located.


If the water pump is leaking, then you need to replace it, replace the thermostat as well. Make sure you have got all the air out of the cooling system, when you refill the coolant, by undoing the top hose of the radiator till water comes out, likewise with a heater hose, then start and check, when the temperature is right the fans should cut in, keep an eye on the temp guage whilst doing this.
Hope thgis helps

Water leak from somewhere around the fan belt?


It is the water pump. The seal is leaking and ruptured.
You must replace the water pump. Can't just install a seal.
The water pump has a pulley attached to it.

94 honda is overheating


I dont think the transmission has anything to do with your overheating problem...Check to see if there is water in the oil...If there is water in the oil then it could have a head gasket problem..Did you ever replace the thermostat? If it is stuck then it would also cause overheating...Excessive exhaust backpressure because of a clogged catalytic converter could also cause overheating..Also check belt tension and condition. A loose belt that slips may prevent the water pump from circulating coolant fast enough and/or the fan from turning fast for proper cooling...Another thing it could be is a faulty Water pump -- Any wobble in the pump shaft or seepage would call for replacement. In some instances, a pump can cause an engine to overheat if the impeller vanes are badly eroded due to corrosion or if the impeller has come loose from the shaft. The wrong pump may also cause an engine to overheat. Some engines with serpentine drive belts require a special water pump that turns in the opposite direction of those used on the same engine with ordinary V-belts... Also check the Fan -- With mechanical fans, most overheating problems are caused by a faulty fan clutch, though a missing fan shroud can reduce the fan's cooling effectiveness by as much as 50% (depending on the fan's distance from the radiator) which may be enough to cause the engine to overheat in hot weather or when working hard.
