My 2003 avalanche overheats pulled radiator out and cleaned it replaced thermostat


Right start by running engine and testing for the radiator getting warm all over and not just on the outside tubes ,then clog up in the centre where the fan is first so if its warm on the outside and cold in the middle where the fan is then this is your problem ,Now assuming this is ok and checks out then the main cause of failure for overheating is the water pump ,it may not leak but what happens is a plastic impeller on a metal shaft and the plastic impeller comes loose on the shaft so the shaft turns but the impeller doesnt or very slowly causing the engine to overheat ,also try bleeding off the top heater hose at highest point but i doubt if this is your problem as most cases i get are where the impeller comes loose

I have replaced the impellers 2 times on my one year 5hp 2speed Waterway spa pump. There is a separate plastic ring that floats on the front of the impeller that seems to cause the problem. It seems to...


Thank you for posting your question here on Fixya.com.


The cause for those parts to fail is almost always running dry or poor water flow. Check for things like partially closed valves, dirty filter(s), leaks in the pump allowing cavitation or poor plumbing with too many elbows stacked together as the cause. Your solution(s) will vary depending upon the cause of the failures.

My 2000 VW is leaking coolant all over the place. I've had it to TWO VW mechanics who tell me it isn't leaking, but I've had to replace the fluid three times because the overheat light comes on. Anyone...


You may think you have a leak from topping off your reservoir three times. You can also have a leak but puddle not present under your car. Unless you have a leak a pressure test will not solve your problem, it will just tell you you don't have a leak. Either way you have a cooling problem.

Original VW water pumps has a plastic (composite) impeller to draw coolant from the reservoir and pressurize the cooling system. That impeller is attached to a shaft and the water pump pulley on the other end of it. When it cracks from the shaft connection it will spin slowly or not at all while the pulley is spinning together with the engine. In short.. it broke off and doesn't spin at all while the pulley is spinning. When that happens it doesn't pump coolant around the system and causes your engine to over heat. From over heating (coolant not flowing) comes evaporation of the coolant due to excessive heat, hence, the need to top off your reservoir again and again thinking you have a leak.

Solution:
Replace with aftermarket metal impeller water pump and have another VW independent shop to install it for you. It would also be a good time to have a timing belt service since this needs to be removed to get to the pump.

I turned my starite pump on and it just hummed for about 5 seconds then cut off. What could be wrong?


Your pump motor or impeller is seized. Disassemble the pump housing and check the impeller to see if it spins freely. If not then check for debris, if impeller appears to be free of debris, then check the shaft seal and motor. If the shaft seal is leaking water, then the motor bearing is likely rusted and will need to be replaced. There are 2 bearings, replace them both along with the shaft seal

Leaks when filling


It could be a swollen impeller inside the pump causing it to wear a hole in the plastic housing and making the humming noise .It,s fairley easy to replace as it clips on to the end of the motor.Hope this helps.

LG LDF8812ST WONT DRAIN JUST INTERMITTENT BUZZ NOISE


Hi, there may be an obstruction in the pump housing that is causing the motor to freeze or, the impeller may be stripped and , jamming the pump. this will cause the hum you are hearing. the best way to inspect is to , extract the drain pump by, removing
the bottom drain filter housing or sump. manually
move the pump impeller to self it is moving freely. if the impeller is stripped, it will not be able to produce the draining surge necessary to pull the water out.

If the impeller is fine and, there are no obstructions visible, this will confirm pump failure.. replace the pump in this case


Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

Pump disassembly


I removed the impeller on my DW761UQB. The instructions were molded into the plastic pump housing. This is how I DID MINE: Remove motor mount screws. Remove the chopper screw (screw only goes into impeller, not motor shaft). Remove chopper and rotate/remove strainer. Place socket or wrench on impeller tip and place another wrench on rear of motor's plastic fan. Unscrew fan from impeller shaft ( threads are LEFT handed, turn CW). Once fan is 'backed off' of the impeller, CAREFULLY pry the motor/fan from pump housing (impeller is attached to motor shaft via splines). Don't crack the delicate plastic pump housing. Mine was stuck, but separated with moderate force. Now remove the impeller/seals from the pump housing. This worked for MY above mentioned model, I don't know what other models it applies to. I am not a pro.
