When there is a load on the motor and it is surging this is an indication of not enough water getting to the front of the pump.
Check the water flowing inside the tub going from the jet opposite the suction cover.
Sounds to me like you may be getting cavitation because the pump is pulling in too many air bubbles from the jet.
Close the air control and/or move the direction of the eyeball from pointing at the suction cover and see if that helps.

2007 vue 2.2 4 cylinder How do you get all the coolant out. removed radiator drain plug coolant cap and only got 1 gallon out pan- system was full manual showed a little over 2 gallon capacity


Cooling System Draining and Filling (Static Fill)

Draining Procedure

    Warning! In order to avoid personal injury, do not remove the cap or open the cooling system drains from a hot system. Allow the system to cool first.


    Click to Enlarge
    ImportantA 7.6 liter (8 qt) coolant container will be needed.
  1. Place the coolant container under the radiator drain **** located at the bottom of the right radiator end tank.
  2. Open the drain **** and drain the coolant. A small amount of coolant will drain from the system.


  3. Click to Enlarge
  4. Remove the surge tank cap from the surge tank and the coolant will drain from the system.


  5. Click to Enlarge
  6. For LE5 and LAT vehicles, if the engine block needs to be drained, a drain bolt is located near the bottom of the water pump assembly.
  7. Inspect the coolant.
  8. Follow the appropriate procedure based on the condition of the coolant.
  9. • Normal in appearance--follow the filling procedure.
    • Discolored--follow the flush procedure. Refer to Coolant System Flushing .

    Filling Procedure

      Caution! All entrapped air must be purged from the powertrain cooling system before the final coolant level can be determined. Proper coolant level is critical to avoid engine damage.
      ImportantThe vehicle must be level when filling the cooling system.
    1. Slowly add a mixture of 50/50 DEX-COOL antifreeze and clean water to the coolant surge tank. Fill the cooling system as indicated below:
    2. • For LE5/LAT vehicles when the engine block is not drained, add 3.5 liters (3.7 qts)
      • For LE5/LAT vehicles when the engine block is drained, add 6 liters (6.3 qts)
      • For LZ4/LY7 vehicles, add 5 liters (5.3 qts)
    3. Start the engine and check for leaks.
    4. Run the engine and cycle the vehicle from idle to 3,000 RPM in 30 second intervals until the engine cooling fan comes ON, the engine cooling fan turns ON at approximately 102°C (216°F). Repeat this process twice before the engine is turned OFF.
    5. Return the engine to idle, and idle for 30 seconds, then turn the engine OFF.
    6. Allow the vehicle to cool, before adding additional coolant.
    7. ImportantThe level in the surge tank will return into the cold fill range once the vehicle cools.
    8. Add additional coolant to the surge tank until the level is approximately 13 mm (0.5 in) above the surge tank seam.
    9. Install the coolant surge tank cap.
    10. Hope this helps.

Drain pump running as in flood protect mode even with door open, At first I thought the float was sticking due to sludge deposit.


The main controller and circuit board may have a short. Switches take their instructions from the main board and if a power surge or power outage occurs, one or more diodes, resistors or capacitors are faulty.

Fresh water and pump is on but no water is coming from taps


Does unit use water ONLY from pump? If so, make sure pump is actually running by feeling the pump. Is it emitting a small vibration? That is normal and probably means pump motor is running normally. If pump housing is excessively hot, pump may be locked up. If all appears normal and still no water, most likely culprit is broken impeller inside pump "Wet End" housing. Try disconnecting INLET hose to pump and check for presence of water. If none, pump is not your issue, your tank is dry. Also check pump OUTLET (pump off) for water. Disconnect hose, switch pump on momentarily. If pump discharges water here, you have a crimped or stopped up line or possibly a stopped up filter, if so equipped.

I just changed the water pump, thermostat, and flushed the heater core. I ran the car for a while with the surge tank cover off and kept filling it. As soon as I got on th e-way it overheated.


The surge tank should only have a little water in it, not full. I hope you didn't overfill it, this can cause your problem, but I would look at the radiator and make sure it is not plugged and your cooling fans, make sure they are running as well. Then last but not least your water pump may be bad even though you changed it, check for good flow through the radiator, if flow is good and strong then check the fans. You have already done most of what can be done, make sure the thermostat is not in backwards, in fact take it out and see if the car runs cooler, this will help pinpoint the issue also.

Water surging back to pool when shut off


sounds like you have air built up inside the filter when the pump shuts off. the most likely cause is a suction side air leak, bad lid o-ring or union o-ring or maybe even the threaded fitting going into the pump. When you turn the pump off, you may be able to see water squirting out wherever the leak is. Once you find/fix the suction side leak the filter should stay filled with water and not surge backwards when the pump turns off. Make sure you keep the filter clean as well.

I had a power surge and ever since my ice maker won't fill with water. If I manually pour water in the ice maker, it will dump the ice.


the water pump is burned out.
the power surge most definitely caused this.
locate the water pump and with a multi meter test for power.Replace.

My pump will surge on, run for a while and shut off, then start up again. Unplugging and replugging makes no difference. What to do?


Check to be sure water level is up where it belongs then check to be sure your skimmer weir door is free. If this is stuck water in the skimmer will run the pump for a moment then the water will run around the door and fill the skimmer to start the cycle again.
