Water Pump Impeller Stuck

It's all about using more leverage in a way that doesn't damage the parts you're trying to protect. You also want to make sure your lever pries it straight out and not sideways. You're wise to take your time to do this right and think about it for a while and ask questions. What you're looking for is a very subtle pop that gets it loose without bending anything. I've not done this before on this particular pump, but have watched the videos to which you refer.

 

You're not trying to protect the impeller you're removing The impeller floats in a plastic case the gray crap all around the impeller The impeller is spun by the magnet and the electricity going through the plastic this is why it's a mag drive pump and really should have very little to know where but be that as it may apparently heat and maybe the glycol or whatever in the coolant tends to swell the plastic that's wrapped around the rotor the part you're trying to remove or the impeller so you may need to grab it with some vice grips or what have you You can mess it up pulling it out that's okay You're going to throw it on the floor and then you're going to take some if necessary very fine crocus cloth which is fundamentally sandpaper that won't be damaged by getting damp or wet and run it around that hole you just pulled the impeller out of see the broken plastic on the impeller it's usually white it's peeling up That's what's trying to stick into the plastic hole that you're pulling it out of now clean up that plastic a little bit make sure it's smooth so your finger can run around it without stopping. Now take your new $37 impeller and stick it in the hole Make sure you can pull it in and out at different rotation angles it should fit smoothly not be tight If it is sand the hole a little more with very fine sandpaper we're not trying to remove a 16th of an inch at a time. Once you're impeller fits in that hole nicely put the bolts back in put it together but don't bolt it to the car plug it in have tech or your scanner plugged up and call up the water pump and turn it on now you can look under the hood and see the water pump impeller spinning It can do that for a minute or less than a minute dry and not hurt anything You can put your hand on the impeller and feel it against your fingers ding ding ding. So it's running everything is copesthetic. Now put it all back in the water pump the thermostat and all that.

 

You could just take your burnsmatic torch and heat the very tip of that piece of metal and that impeller will slide right off of there You don't have to melt it it just needs a little nudge

 

Are you able to rotate the rotor with the vice grips? Try rotating and pulling out at the same time.

Ohh... Now that I see what you're dealing with, I don't understand why you're only trying to replace the impeller? Doesn't the replacement pump come with both an impeller and motor?

Basically, that impeller has a fastener mechanism that has to be release with a special tool or is designed to forever be mounted and is not something that can be removed. You'd have to destroy one to see what's inside to be certain about how it fastens.

 

It's similar to the impeller in the battery fan just smaller I used my little Kline screwdriver to pry the tab back and pull the impeller off of the motor shaft He's trying to pull the whole impeller out of the hole. I'm guessing the plastics got him the stuff that frays

So with tools and a pair of pliers you can't even pull that out even if you were to destroy the impeller the black thing that moves the water. Well then I guess you're in a real pickle try and spray some WD-40 or Aerokroil allow it to soak in to where the plastic he's peeling off is sitting when it's assembled then maybe it'll pry out Don't be afraid to pull on it while twisting You're working against that white plastic that's probably broken off and gouged into the plastic wall of the hole or swollen and is grabbing it really tight That's all you're up against the impeller is not physically really super stuck maybe you're just afraid to pull it off of there because you're going to damage something If you damage something that's why you generally buy a new pump just a few years ago people weren't even taking these apart they just dropped them on the ground bolted in a new one then all of a sudden somebody decided well geez this is like the inside of a washing machine pump what gives We should be able to buy just the part that rotates The rest of it really shouldn't be breaking per se. There is a circuit board in the main body of the unit but it's completely sealed and unless it electrically fails or burns up well it should be good to go.

 

You need to be carefull with heating and prying because you can damage the shaft and the edge of
the water pump. Then you'll be buying a new water pump.
The plastic of the impeller is probably cracked. And the magnet is also holding it in.
Take a credit card, or cards from a deck of playing cards and ease them in between the impeller
and pump. Rotating the cards. You should should be able to get the plastic out of the way to
remove the impeller.

 

The one or two that I've had the yank out here in the yard Left my new scratches in the grayish black plastic that the impeller and plastic covered magnet or whatever that is float in I just smooth that out with some like 120 grit crocus cloth. And then wipe that with WD-40 or something on a rag then drop the other impeller back in that hole Make sure it spins like all the YouTube videos you feel the magnet when you spin the impeller you watch it stop and you see it kind of tick back that's the magnet activity going on that's what you're looking for If everything's right inside the main body of the pump in the circuit boards not burn up You should be able to put it together not install it on the car but plug it up call it up with tech and watch it run and it should be dead silent for the most part.

 

Take it to an auto shop with a huge air compressor and put it on max PSI and blast it. I bet it pops right out.

 

Problem will be getting air behind the impeller The impeller is in the water moving the water from the inlet outlet which are in front of the pump behind the pump or the impeller sitting in the plastic there's nothing happening it's all sealed That's why usually it can't get stuck in there any kind of real serious way endless I don't know the car wasn't used for a while and the antifreeze was drained out and it dried up in place yuck I can't even imagine usually you can grab that impeller shaft with pliers and have a quick snatch and it comes right out Not sure what's happened here The water pump ran itself to death in the plastic is melted and literally welded the pieces in place? Wild. Then I guess a new pump will have to be in the budget I'm sure somebody here has one that they've got laying over on the floor that they didn't bother changing the impeller on they just replaced the pump.

 

Any update?????

 

I have one just like yours, and I'm thinking about using a pulling tool to pull it outto inspected

Normally, you can just pull it out with your hand using a bit of force. But if the water pump propeller was damaged inside, like the coating of the magnet has cracked open then it will stick inside the pump..
